Dna Notes

desoxyribonucleic acid Deoxyribose acid (desoxyribonucleic acid) Ribonucleic Acid (ribonucleic acid) deoxyribonucleic acid is stored in the nucleus, ribonucleic acid is lay out in the cytoplasm Nucleic Acids atomic depend 18 long chain molecules and their edifice blocks argon called nucleotides, more(prenominal) complicated than the acids Nucleotides atomic number 18 compromised of a pentose plunder, a phosphate, and an essential go off 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 handbag pentad Bases in DNA: 1. vitamin A 2.Cytosine 3.Thymine 4.Guanine 5.Uracil A, C, T and G are lay out in DNA. A, C, U and G are found in RNA. Adenine, Thymine and Uracil are receptive of forming two total heat bonds while Cytosine and Guanine hindquarters form three. Adenine and Guanine are purines Cytosine, T hymine, and Uracil are pyrimidines phosphate + plunder + organic base ---> nucleotide + 2 water Nucleotides dismiss be connected together by a compaction 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 reprise ringlet The back one is do 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 makes A and U, C and G. DNA Replication: The DNA double heli! x has to unwind and the two strands need to seperate Free nucleotides which are floating around in the nucleus for complemental pairs with the nucleotides of two 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 pith to each other Because the organic base will tho fit with one other one complementary base pairing,...If you want to get a full essay, order it on our website: OrderEssay.net
