Advantages of Genetic Engineering in Animals

Advantages of Genetic Engineering in Animals How successful would the Enviro-pig be if released into the general pig population in terms of longevity of the trait and continued benefits to the environment? And do the ethical issues stacked against the Enviro-pig validate its modified presents in the genepool? DNA is the foundation of all genetic material found in every living organism on earth. Commonly known as its full name Deoxyribonucleic acid, it is an electrically neutral group of atoms held together in a chemical bond known as a molecule . In this case a biomolecule produced by a living organism composed of nucleic acid, carbohydrates and proteins . This mixture is coiled in two biopolymer strands forming adouble helix. Biopolymers being a biomolecule of a polymer , which is a large molecule, composed of monomers . These biopolymer strands are composed of thirteen nucleotide monomers bonded in a chain, in turn called a polynucleotide . Nucleotides being singular polynucleotides composed of a nucleobase (co ntaining nitrogen). Being split into four bases each nucleobase is as followed: Guanine (C 5 H 5 N 5 O): Pairing in sequence with cytosine, guanine is derived from purine. Purine is an organic compound structured from a pyrimidine ring fused to an imidazole ring (called a pyrimidine-imidazole ring ). The base is represented as ‘G’. Adenine (C 5 H 5 N 5 ): Similar to that of Guanine, Adenine is derived from purine. In addition it’s an important part of adenosine triphosphate (ATP). ATP is the nitrogenous base adenine bonded to a five carbon sugar. These molecules have the ability to phosphorylise and add phosphate groups to other molecules. This allocation of phosphates allows energy to be released. It is this energy which is used in the cells of living organisms. The base is represented as ‘A’. Thymine (C 5 H 6 N 2 O 2 ): Combining with Adenine this nucleobase is often replaces with uracil in RNA . It is also the common cause of mutations in DNA. When in the presence ofultraviolet light, radiation causes alterations in the DNA molecule that inhibit normal function. These â€Å"kinks† are referred to as pyrimidine dimers . The base is represented as ‘T’. Cytosine ( C 4 H 5 N 3 O) : Pairing with guanine this base is a pyrimidine derivative. A heterocyclic aromatic ring that when as cytosine triphosphate (CTP) can performance as a co-factor to enzymes, able to transfer a phosphate to transfigure adenosine diphosphate (ADP) to adenosine triphosphate (ATP). Nucleotides of a DNA stand line up so each sugar and phosphate molecule connects. As said an adenine only pairs with a thymine and a cytosine only pairs with a guanine. The sugars are linked together by phosphate clusters via phosphodiester bonds, branching between adjacent sugar rings. The dual helix is stabilized by the bases of hydrogen bonds, before bunching together and constricting a vase line of rungs. All are curled to gether with multiple strands to form a chromosome . Being such a delicate sequence of codes , all of which contributing towards every characteristic in an organism, if altered or affect in a minor way a secession of errors and mutations can occur. Mutation is when an alteration of a nucleotide arrangement in the genome causes changes in an organism. Even if by a small change, the structural integrity of a creature can differ. But if this large sequence of coding is only effect in one base, in one strand, located in a single cell, the error theoretically should not affect the creature. However through Protein synthesis and mitosis a fault can replicate and spread.
