Question

The nitrogenous base found in place of thiamine in RNA molecule is-

Answer 1

The nitrogenous base found in place of thiamine in RNA molecule is Uracil.

Uracil binds to the adenine through two hydrogen bonds in RNA.

In DNA, thymine is present in place of Uracil as the nitrogenous base.

Thus he correct answer to the question asked by you is ( b ) Uracil.

Answer 2

Answer:

The 'nitrogenous base found in place of thiamine' in RNA molecule is uracil.  

Explanation:

RNA is a 'polymer' with a 'ribose sugar and phosphate' and four different bases: 'adenine', 'guanine', 'cytosine', and 'uracil'. The first three which is found in DNA, but in RNA, 'thymine is replaced by uracil'.  

Uracil is an energetically 'less nitrogenous base' to produce than thymine.  

Uracil is produced by 'chemical degradation of cytosine'.  

When compared to RNA, the quantity of uracil is important but its lifespan is not very much good.
