Answer:
Thymine and uracil
Step-by-step explanation:
DNA is called deoxyribonucleic acids .It consist of sugar, bases and phosphate group.
There are four bases
1.Adenine
2.Thymine
3.Cytosine
4.Guanine
Nucloetide: It consist of sugar , one base out of four bases and a phosphate group.
Nucleoside: It consist of sugar and bases.
RNA: It is also ribonucleic acid.It consist of sugar, bases and phosphate group.
There are four bases
1.Adenine
2.Guanine
3.Cytosine
4.Uracil
Hence, DNA use Thymine while RNA uses Uracil.
