ANSC20010 Genetics and Biotechnology Assignment Sample Ireland

The field of genetics and biotechnology is the study of how to improve human health by modifying genes. It covers a wide range of methods, from molecular biology to immunology, that allows scientists to explore the genetic basis for physical traits and diseases. This research can lead to new treatments for serious illnesses such as cancer or heart disease, as well as new insights into why some people are more able than others to make great contributions to their careers or families.

“Genetic improvement” takes different forms. It can select for better outcomes for people who face particular threats such as disease, injury, or developmental disabilities. It can clear traits that hold societies back or make them more productive. This increased output can greatly benefit everybody in society and lead to better futures for humanity as a whole.

One of the great examples is agricultural biodiversity, with grains and other easily-grown crops farming needing to be adapted to cope with all the possible soil types, climates, and pests. Genetic modification lets crops better adapt to their own soil and take advantage of new pests. For example, there are many types of nematode worms that attack fruits and vegetables so it would be good if we found ways to keep them out of crops.

In this course, there are many types of assignments given to students like individual assignments, group-based assignments, reports, case studies, final year projects, skills demonstrations, learner records, and other solutions given by us. We also provide Group Project Presentations for Irish students.

In this section, we are describing some tasks. These are:

Assignment Task 1: Describe the genetic consequences of meiotic cell division and fertilization and explain the particulate nature of the gene. 

The genetic consequences of meiotic cell division and fertilization can be significant. For example, a person’s sex might be determined by the combination of chromosomes that are received during gamete formation. This information is used to determine which genes will be expressed in the embryo and fetus. If one or more eggs get lost during meiosis, this could lead to a child with incorrect sex or an individual with health problems as a result of different semen characteristics (e.g., an earlier miscarriage) because of one or more once-important pieces of genetic code being lost.

The particulate nature of the gene is a result of its location on chromosomes. Each chromosome has one copy of each species’ genetic material. The form and function of these genes are determined by the combination of this genetic information and environmental factors, which can be studied in small samples from different parts of the world or from individual cells ( DNA). The distance between genes can affect the gene’s form and function. This is called “gene-environment variation” or even “adaptation,” which happens when genes vary in this manner due to environmental differences.

The interaction between different species of organisms can have a direct impact on gene expression. Lapses of time and predation can cause the synthesis of new libraries of RNA (intermediary products then pause the translation process), which could disrupt the regulatory system for specific genes that encode some intracellular proteins (current digestive register).

Assignment Task 2: Outline chromosome structure and the concepts of genetic recombination and linkage.

Chromosomes are pieces of DNA that organize the cells in a living organism. They carry the genetic information for each individual cell, and as such, they play an important role in the development of embryos and fetuses. Chromosomes also play a significant role in gene expression, which is how different genes work together to create proteins.

The nucleobases that make up DNA vary between species. Most vertebrate common variants are diploid, meaning that they contain a complement of two copies of each gene (the haploid state). However, these complementary sets of genetic information are scattered throughout the DNA chain. This translates into an effective number of proteins equivalent to only one copy for every gene in most species (although if one were to count the actual number of genes there are twice-colonized N places at each end of the genome servicing reproductive functions).

One way animals separate from plants is by duplicating their chromosomes during meiosis; this is essential to proper embryonic development and keeps the embryo from being harmed by crossing two sperm and reserving resources for developing certain cells. In contrast, plants use a variety of mechanisms to prevent even the nearest relatives from mating- some have lost any ability to have sex due to lack or inactivation of genes and some have mechanisms that keep portions flush at each cleavage division and expel upsides.

Assignment Task 3: Outline nucleic acid structures and conceptualize gene expression.

Nucleic acids are pieces of DNA, which contain the genetic instructions for a particular organism to grow and develop. The structure of nucleic acids is important because it governs how genes can be expressed in an organism. Additionally, understanding the way nucleic acid structures control gene expression can help physicians diagnose diseases and treat patients with medical conditions.

For instance, a scientist researching cancer development knows that the tumor is propagating uncontrollably after its genome has been studied. Attacking cancer because of its damaging nature is not advisable because there are other places of the genome causing the individual to grow; the location where treatment is applied may cause chaos each time a cell divides or reorients.

Since scientists would not attribute all of their woes to one event (like after disrupting cells with radiation and then falling into a black hole), they know to be extra cautious when examining their target(s) and any surrounding areas.

Assignment Task 4: Describe the molecular basis of mutation and mutagenesis.

Mutagenesis is the process of creating new mutants, and mutations are those that differ from the normal. Mutations can be caused by natural or man-made factors. Natural mutations include errors in DNA replication, mutation of amino acids within proteins, and misshapen chromosomes. Mutation can also arise through chemical reactions between two molecules such as hydrogen peroxide and water (seeding).

Mutations cannot, by themselves, be a result of natural or unnatural causes. Mutations are already formed upon conception because, at this point in the process of replication, selfing is not possible. When mutations do occur they can be either beneficial or lethal. Overall, re-replicating something damaged before will usually cause death. On the other hand, re-replicating good information itself is usually beneficial to the organism.

Assignment Task 5: Outline methods used for in vitro laboratory manipulation of DNA.

The three main methods used to manipulate DNA in vitro are heat, chemicals, and physical force. The first two techniques use heat to cause the target DNA strands to break or cleave. The third method uses chemicals to modify the nucleotides in the target DNA so that they can no longer bind together without producing a complementary strand of DNA (i.e., breaking them up into their individual pieces). The effect produced by the various methods is observed using gel electrophoresis or other biochemical assays.

In higher organisms, phenotypic tissues highly responsive to developmental control (such as neuronal tissue) are attenuated in time during development, when environmental signals trigger responses that are either normally muted through behavioral adaptation or aborted through cell turnover in an attempt to revert back to a previous stable steady-state without inducing evolutionary change. Targeting these behaviourally regulated developmental specific somatic tissues may thus give new opportunities for drug discovery.

Assignment Task 6: Describe methods used for molecular cloning of recombinant DNA. 

Cloning methods involve the cloning of DNA from a desired gene or region by using restriction enzymes to cut out the desired segment and then re-forming that section of DNA with a new enzyme. The technique is used for various purposes, including genetic engineering, medical research, and agriculture. The section of DNA after the restriction is severed can then be carried into bacteria in a plasmid vector, transforming it when introduced into a host bacterium.

Genes regulate developmental time in particular cells, causing them to round up (die maturely) or down (die earlier) as with aging in most cases or carrying out a specific morphological change during development for instance malformations. RNA instead of DNA serves as the carrier of genes, which can be transferred via retroviruses or transposons which then inserts the gene into RNA-containing genomic loci otherwise devoid of regulatory capability.

Cellular structures and their regulation via genes are regulated not only through what they depend upon to function but also how they build themselves and how they react to external conditions — how being randomly engaged by scent in flowers versus hoarding calcium ions depending on either one response exclusively would be rather unlikely while plasticity is very much interesting.  

Assignment Task 7: Outline methods used for genetic engineering in plant and animal agriculture.

There are a variety of methods used for genetic engineering in plant and animal agriculture, including germplasm selection; crossing plants with other types of animals or vegetables to improve their production tolerance; mutagenesis (changing the genes within an organism so that they no longer work properly); transformation ( transferring parts of a plant or animal into another form); and cryopreservation (holding living things in cold water until they can be revived).

Assignment Task 8: Discuss practical applications for transgenic plants and animals.

The use of transgenic plants and animals for practical purposes has been increasing rapidly in recent years. This is due to the many benefits that these organisms can offer, such as enhanced production, increased lifespan, or decreased susceptibility to disease. Many different types of beneficial applications are possible using transgenic organisms: from food safety to agricultural productivity; from environmental protection to medicinal research. Some of the major advantages that transgenic organisms have are immunity to diseases, pesticides, and herbicides, and higher yield and quality of harvested products. Also popular are animals that derive their meat from animals that do not even belong to the same species.
