Main Structure
Bases in DNA
Guanine = G
Cytosine = C
Tymine = T
Adenine = A
Cytosine = C
Tymine = T
Adenine = A
The bases are attached (G - C) and (A-T)
Pictures' Description
It is a chain of nucleotides that are attached by a phosphate; each nucleotide is one phosphate, one sugar and one base.
There are two chains of nucleotides that are connected by their bases; they have to be adenine with tymine and guanine with cytosine.
Starting the DNA replication, the original pairs will separate.
DNA replication, RNA will replace the bases pair, except the tymine that will be replaced by uracil.
This is how DNA structure looks when the base pairs are connected and the blue double helix represents the sugars and the phosphates joined together.
