Question

What are the 4 nitrogenous bases of RNA ?
(A) Adenine, Guanine, Cytosine, Uracil
(B) Adenine, Guanine, Cytosine, Thymine
(C) Adenine, Guanine, Ribose, Deoxyribose
(D) Adenine, Cytosine, Deoxyribose, Uracil​

Answer 1

Answer:

option A is the answer bro. coz in ena uracil is present instead of thymine

Answer 2

$\LARGE{ \underline{\underline{ \sf{Required \: answer:}}}}$

RNA is a nuclei acid comprising of a single strand and is made up of nucleotides with spaces in between. The nucleotides are:

1. Adenine
2. Guanine
3. Cytosine
4. Uracil

So, The correct option is (A) which matches with the above nucleotides. Thymine is found in DNA which is replaced by Uracil in RNA.

Do you know? The backbone of the nucleic acids to maintain their uniformity is phosphate groups and pentose. And you should note that, the pentose sugar is ribose instead of deoxyribose in RNA.

There are three types of RNA on the basis of their functions: ribosomal RNA (r-RNA), messenger RNA (m-RNA) and transfer RNA (t-RNA) which have their specific work or function.
