A DNA molecule is shaped like a twisted ladder ,the rungs of the 'ladder' are the bases ,they are called nucleotides.A nucleotide is made up of phosphate ,sugar and a base.The bases pair (a-t) c-g).The sides of the 'ladder' are made out of phospates and sugers.
The order of the bases makes up the genetic code.The code tells the cells how to assemble the protens that make up our body.The bases are the genes.
Adenine and Thyanine, Guanine and Cytosine
Adenine and Thymine make up one pair and Cytosine and Guanine make up the other pair. Uracil pairs with Adenine in RNA.
DNA base pairs.
The base pairs found in DNA are adenine with thymine, and cytosine with guanine.
The correct base-pairing rules ofr DNA. . .The base pairing rules for DNA areA pairs with TG pairs with CC pairs with GT pairs with A
four base pairs
In DNA,adenine----------thyminecytosine----------guanine
So essentially the difference is that in DNA-DNA base pairs thymine bonds with adenine while in DNA-RNA base pairs thymine bonds to uracil.
base pairs are broken apart
THMINE
cytosine
4000: 2500: | 2000: 400: | (the amount of strands represents the size of the DNA strands)
In DNA the base pairs are Adenine with Thymine and Guanine with Cytosine. In RNA Thymine is replaced by Uracil so the base pairs are Adenine with Uracil and Guanine with Cytosine.
A (Adenine) always pairs with T (Thymine).
