DNA has the purines Adenine&Guanine and the pyrimidines Cytosine &Thymine
RNA has the purines Adenine&Guanine and the pyrimidines Cytosine & Uracil
Figure it out

Among the (5) nitrogenous bases found in nucleic acids, thymine is a pyrimidine base found in DNA only.Cytosine is present in both. Apart from these two, cytosine also exists as CTP/ cytidine triphosphate utilised in STP synthase reactions. This means apart from the nucleic acids, it is a part of the machinery of this synthetic system. So, it is wrong to say that thymine is a pyrimidine found in RNA. Also, it is incorrect to say that the 2 bases are found only in nucleic acids.

False. Uracil is in RNA instead of Thymine.

no. cytosine is definately found in both but thymine is found only in dna whereas uracil (a 3rd kind ) is found only in rna.

ok DNA has ATCG, RNA doesn't have Thymine, its replaced with Uracil. so RNA has AUCG, A goes to U and vice versa and G and C remain the same. hope that helped!

the components of DNA are
adenine (A), cytosine (C), guanine (G), and thymine (T).
and in RNA the tymine changes to
uracil (U).
So that statement is true

false, RNA has uracile instead of thymine
