Compare and Contrast Dna and Rna

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.

A and G contain 2 rings and are referred to as purines whereas C and T contain one ring and are referred to as pyrimidines. 2 of those strands combine along to make the acquainted double helix structure of DNA. the 2 strands link to every alternative via interaction between the bottom pairs in a very extremely specific method. A solely pairs with T and C solely pairs with G. This specificity, called complementary base pairing, arises via hydrogen bonds. every C-G pairing involves 3 hydrogen bonds between the bases, whereas every A-T bond involves solely 2 hydrogen bonds leading to a weaker interaction.

Discoveries in DNA, cell biology, evolution, biotechnology have been among the major achievements in biology over the past 200 years with accelerated discoveries and insights over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be most important and describe their significance to society, health, and the culture of modern life.

This paper explores the history and some interesting facts about DNA. The last couple centuries have seen an exponential growth in our knowledge of DNA. The history of the DNA can be traced back to multiple devoted scientist. This article attempts to summarize, and review the basic history of DNA while providing some fascinating information about it.

DNA is important to organisms because DNA carries hereditary information on to the next generation of cells during the process of replication. This is important for the health of an organism because when a cell divides because it becomes too large; it needs a copy of the genetic information in order to fulfill necessary processes in order to keep the organism alive.

Understanding DNA can take a lot of studying and confusion to even get the general idea of the concept. The structure of DNA is very complicated and complex to understand, but researchers James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin all developed the idea of the DNA structure in 1953. Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including 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,

Strands of the DNA are composed of a sugar and phosphate, portions of the nucleotides while the middle parts of the DNA are made up of nitrogenous bases. The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form pairs with bases on the other side, like rungs. The nitrogenous bases on the two strands of DNA pair up, purine with pyrimidine (adenine with thymine and guanine with cytosine) and are held together by hydrogen bonds. DNA has a spiral staircase-like structure. The steps are formed by the nitrogen bases of the nucleotides where adenine pairs with thymine and cytosine with

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 rungs of a ladder, and are joined by alternating phosphate and sugar groups, which may be compared to the ladder 's sides or legs. The bases adenine and thymine form what is known as one base pair, and the bases cytosine and guanine form the second base pair.

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

Structure and function in Biology is a broad concept that can be explored within a diverse range of topics across the subject matter. The following essay will be focussed mainly on the subject of Deoxyribonucleic Acid, or more commonly DNA. DNA is a highly complex, intricate and extraordinary macromolecule found within all living cells. DNA is a "biochemical noun" and can be defined as "...a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information." [Oxford Dictionary, c2016] DNA is found in the nucleus of eukaryotic cells, enclosed within a double membrane. Eukaryotic cells are multifaceted and require a high level of regulation to ensure smooth functioning. The double membrane of the nucleus allows gene expression, a key function of DNA, to be efficiently regulated.

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.
