Describe And Comparing The Chemical Functions Of DNA And DNA

The four bases found in DNA are adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T). A fifth pyrimidine base, called uracil (U), usually takes the place of thymine in RNA and differs from thymine by lacking a methyl group on its ring.

Two structural differences between DNA and RNA would be that RNA contains ribose while DNA is missing the hydroxyl group form its ribose. Also, RNA is created by transcription of a gene locate in the cells of DNA. DNA is doubled stranded whereas RNA is single stranded.

D)Nucleic Acids monomer(s) are called nucleotide. The functional group is dna(Deoxyribonucleic acid) and rna(Ribonucleic acid). The linkage type is covalent bonds and hydrogen bonds. The primary function of nucleic acid is to store and transfer genetic material.

Because nucleic acids are polymers of individual nucleotide monomers. Each nucleotide has three parts which are 5 carbon sugar, a phosphate group and a nitrogenous base.

DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose.

A stable DNA structure is formed when the two strands are a constant distance apart. This can only occur when a purine (A or G) on one strand is paired with a pyrimidine (T or C) on the other strand. The purine A can only pair up with the pyrimidine T and the purine G can only pair up with the pyrimidine C. Each letter corresponds to a specific nucleotide base. (Wexler 2) A nucleotide is any part of a group of molecules that, when linked together, form the building blocks of DNA or RNA.

When analyzing DNA it is important to understand it and all the chemicals that it is made of. The first thing that’s important to know is simply what DNA stands for, which is deoxyribonucleic acid. The chemical units are called nucleotides, and each nucleotide has a compound of phosphate sugar which is the backbone, and a sugar deoxyribose. The Phosphates and sugars are the same in all nucleotides but the one thing that is different would be the bases. DNA bases are cytosine, thymine, adenine, and guanine. Each base has specific partner, for example Cytosine will always pair with guanine. And Thymine will always pair with adenine.

DNA is double stranded, while RNA is single stranded. DNA is only found inside the nucleus and RNA can travel outside of the nucleus. There is one type of DNA and 3 kinds of RNA. DNA has a nitrogenous base named thymine that pairs with adenine. In RNA instead of Thymine it has Uracil that pairs with adenine.

The base pairs are very specific on which two can bond together based on the number of rings that they have. Adenine and Guanine are purines, meaning they are composed of two rings. Thymine and Cytosine are pyrimidines which means they are composed of one ring. Purines always bond with pyrimidines, therefore Adenine always bonds with Thymine, and Guanine always bonds with Cytosine. The base pairs are complementary, and almost fit together like a lock and key (CK-12 Foundation, 2017). These nitrogenous bases are bonded together with 1 hydrogen bond. The bases are located in the center of the DNA strand in a specific pattern according to the DNA they are apart of. The name for the base Adenine comes from a greek word “aden” meaning internal gland, and a chemical suffix “ine”. Another base, Thymine, gets its name from thymic acid which it was isolated from, obtained from the thymus gland with the chemical suffix “ine”. Guanine gets its name from guano which the chemical was first isolated from, and the chemical suffix “ine”. Lastly, Cytosine gets its name from “cyto” meaning cell, along with the chemical suffix “ine” that also makes up the other nitrogenous bases (Online Eytmology Dictionary,

DNA is a long curved structure, made up of pairs of four specific bases: adenine, guanine, cytosine, and thymine, is the repository of a code from which all of our cells are made. The code is made up of base pairs which look like the

Deoxyribonucleic acid (DNA) - Is a double helix with two strands that are twisted around one another. Each strand is made of four types of base: Adenine, Thymine, Cytosine and Guanine also represented as (A, T, C, and G). The two strands are held together by the specific mutual attraction that the base, Adenine is always attracted to Thymine and Cytosine is attracted to Guanine. The pair of base will continue to pair together as they structure a spiral staircase. DNA is also passes along through reproduction to their offsprings, one set of DNA from each parent will complete the contribution to the diversity of life.

Deoxyribonucleic (DNA) is the molecule that hold the genetic information of living things. In our body every cell contains about 2 meters of DNA. DNA is copied every time a cell divides. Deoxyribonucleic (DNA) is made up of two polynucleotide strands. Polynucleotide strands twist around each other, forming a shape that looks like a ladder called a double helix. The two polynucleotide strands run antiaparallel to each other with nitrogenous bases this means that the stands run in opposite directions, parallel to one another. The DNA molecule consists of two backbones chains of sugars and phosphate groups. The organic bases held together by hydrogen bonds. Although bases bonded together are termed paired

DNA is composed by a double helix structure. In this structure we can find a phosphate group, a deoxyribose and a nitrogenous base.

DNA is a double-stranded nucleic acid that contains the genetic information for cell growth, division, and function. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A), guanine (G), cytosine (C), and thymine (T). these nitrogen bases are bind with each other through hydrogen bond.

Due to the DNA’s specificity, samples can be utilised for identification. DNA is a nucleic acid composed of deoxyribose sugar bound to a phosphate group and one of four nitrogenous bases (adenine, guanine, cytosine and thymine). Each section of these three components are referred to as nucleotides, which are joined to the phosphate or sugar of another nucleotide by strong covalent bonds to form a backbone. The nitrogenous bases are joined to complimentary bases of another nucleotide (adenine with thymine, guanine with cytosine) to create a double stranded molecule (Figure 2). To complete the double helical structure, the molecule coils to compact it’s contents. DNA molecules can contain up to two million base pairs, with a human genome containing approximately 3 million base pairs. The random assortment of nitrogenous bases as well as the numerous mutations within certain DNA sequences, results in genetically diverese DNA molecules and genomes between individials.
