Which is soluble RNA ?

A

hnRNA

B

rRNA

C

mRNA

D

tRNA

Answer

tRNA

Explanation

Solution

t-RNA is also called soluble RNA or adapter RNA. It forms 10-15% of total RNA present in the cell. These are smallest molecules of RNA, having only 75-95 bases in their polyribonucleotide chain. Molecular weight of t-RNA molecule is 25000-40,000. t-RNA acts as adapter molecules which carries amino acids to the site of ptotein synthesis.
