Dna Notes

desoxyribonucleic acid Deoxyribose acid ( deoxyribonucleic acid) Ribonucleic Acid (ribonucleic acid) desoxyribonucleic acid is stored in the nucleus, ribonucleic acid is lay out in the cytoplasm Nucleic Acids atomic recite 18 long chain molecules and their edifice blocks argon called nucleotides, more than complicated than the acids Nucleotides atomic number 18 compromised of a pentose plunder, a inorganic phosphate, and an essential exculpate radical. The Sugar is devil possibilities: ribose gives RNA and deoxyribose gives DNA The Phosphate H3PO4 (P forms 5 bonds with separate atoms) The Organic Base: the nitrogenous source fivesome Bases in DNA: 1. vitamin A 2.Cytosine 3.Thymine 4.Guanine 5.Uracil A, C, T and G are set in DNA. A, C, U and G are found in RNA. Adenine, Thymine and Uracil are receptive of forming two heat content bonds while Cytosine and Guanine hindquarters form three. Adenine and Guanine are purines Cytos ine, Thymine, and Uracil are pyrimidines phosphate + breadstuff + organic base ---> nucleotide + 2 water Nucleotides undersurface be connected together by a ejector seat reaction amidst the phosphate of whizz nucleotide and the sugar of another. covalent bonds are formed between the phosphate and sugar and a single strand is make with a backbone of phosphate and (deoxy)ribose and an organic base prone to every ribose.

The structure of DNA is a double up ringlet The back one is make of alternating phosphate - sugar groups. The rungs of the twisted ladder which DNA resembles are the organic base pairs. Pairing for DNA makes A and T or C and G Pairing for RNA ma kes A and U, C and G. DNA Replication: ! The DNA double helix has to unwind and the two strands need to seperate Free nucleotides which are floating around in the nucleus for complementary color pairs with the nucleotides of both of the DNA strands. The enzyme DNA polymerase is trustworthy for when the nucleotides which have formed complementary base pairs with the nucleotides on the disused strand now essence to each other Because the organic base will simply fit with one other one complementary base pairing,...If you want to get a full essay, order it on our website: OrderEssay.net
