DNA molecules are composed of two strands that form a helical ascending spiral. They fit together like the opposing teeth of a zipper and are held together by weak interactions called hydrogen bonds. These two strands is a long string of subunits called nucleotides, each dna essay to the one immediately about it and the one immediately below it to form a long chain.
Each nucleotide contains a five-carbon sugar. The five-carbon sugar contains a five-membered ring with an oxygen atom as one of the vertices. Each nucleotide also features a phosphate group and a nitrogen-containing base; these bases are typically represented by adenine, cytosine, thymine, and guanine. The base is attached to carbon 1 of dna essay sugar, biologist denote each of the carbons in the sugar using a number from 1 through 5, where 1 represents the carbon to which the base is attached.
Hire a subject expert to help you with Introduction Into DNA Studies. The genotype of dna essay organism is the sum total dna essay all the genes that it inherits. It is sort of like a blueprint that is designed to serve as a guide in the development of the organism, so that it will become the same kind of creature as the parent or parents that it came from.
For example structural proteins dna essay make up the body of an organism, and enzymes catalyze its metabolic activity. A gene does not build a protein directly, but rather dispatched instructions in the form of RNA, which in turn programs protein synthesis. The molecular chain of command is from DNA in the nucleus to RNA to protein in the cytoplasm, dna essay.
DNA and RNA are long linear polymers, called nucleic acids that carry information in a form that can be passed from one generation to the next, dna essay.
These macromolecules consist of one large number of linked nucleotides, dna essay, each composed of a sugar, a phosphate, and a base, dna essay. Sugar is linked by phosphates from a common dna essay, whereas the bases vary among four kinds. Genetic information is stored in the sequence of bases along a nucleic acid chain. The bases from a specific pair with one another that are stabilized by hydrogen bonds. The base pairing results in the formation of a double helix. A helix structure consisting of two strands.
Genetic information in DNA is transcribed into RNA and then translated into polypeptides, dna essay. These processes occur dna essay transcription and translation when a segment of DNA is transcribed, dna essay, the results is an RNA molecule. Transcription is taken placed because the nucleic acid language of DNA has simply been rewritten as a sequence of bases of RNA; the language is still that of nucleic acids.
The nucleotide bases of the RNA molecules are complementary to those on the DNA strand. Translation is the conversion of the nucleic acids' language to the polypeptide language. Like nucleic acids polypeptides are polymers, but the monomers that make them up are the 20 amino acids common to all organisms.
The genetic instructions for the amino acid sequence of a polypeptide chain are written in DNA and RNA as a series of three-base word codons. Codons are the DNA is transcribed in the RNA, and then the RNA dna essay are translated into amino acids that form polypeptides. Codons in mRNA are read sequentially by tRNA molecules, which serve as adaptors in protein synthesis. Introduction Into DNA Studies. Free Essays - PhDessay.

· Essay # 1. Meaning of DNA: A nucleic acid that carries the genetic information in the cell and is capable of self-replication and RNA synthesis is referred to as DNA. In other words, DNA refers to the molecules inside cells that carry genetic information and pass it Estimated Reading Time: 6 mins · DNA Day commemorates the completion of the Human Genome Project in April and the discovery of the double helix of DNA in This contest is open to students in grades worldwide and asks students to examine, question, and reflect on important concepts in genetics. Essays are expected to be well-reasoned arguments that indicate a deep understanding of scientific concepts DNA: The Roles Of DNA, DNA And DNA. Words | 4 Pages. In a RNA nucleotide the organic bases can be uracil, adenine, guanine or cytosine. Where as in a DNA nucleotide there can be thymine, adenine, guanine or cytosine. In RNA the pairs are UA or CG and in DNA the pairs are TA or CG. Also in DNA the five-carbon sugar is deoxyribose and in RNA the five-carbon sugar is ribose
