What is the structure and bases of DNA?

Answer 1

DNA, deoxyribonucleic acid, consists of two long chains of nucleotides coiled up in a double helix, and joined up by hydrogen bonds between the complementary base nucleotides adenine, thymine, cytosine and guanine. Because it has the remarkable ability of self-replication through the triggering of the production of RNA and various other proteins, it determines individual hereditary characteristics through such processes.

it has a nucleotide consists of a base

a sugar(deoxyribose)

a ohosphate group

Answer 2

DNA's structure is a double helix made up of two complimentary nucleic acid backbones twinned together. Depending on what you mean by structure, DNA helices also bend and twine with each other in the formation of chromosomes.

Answer 3

4 basic chemicals: 2 purines and 2 Pyramidines make up DNA structure

2 purines include Adenine and Guanine (A & G)

2 pyramidines include Thiamine and Cytosine (T & C)

A always pairs with T and G always pairs with C

So in nut shell ATGC make up DNA structure.

Answer 4

DNA has a double-helix structure, with two strands made up of nucleotides. Each nucleotide contains a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). The bases form hydrogen bonds with each other - adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Answer 5

All four bases are composed of a 5-carbon sugar, a nitrogenous base, and a phosphate group.

Answer 6

dna is deoxyribonucleic acid, and the bases are thymine, guanine, cytosine, and adenine. adenine pairs with thymine, cytosine pairs with guanine. the structure is a double helix
