Biology Question on Structure of DNA and RNA
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.
