Which form of RNA has a structure resembling clover leaf
A
rRNA
B
hnRNA
C
mRNA
D
tRNA
Answer
tRNA
Explanation
Solution
Transfer RNA (tRNA) are species of RNA responsible for the transfer of specific amino acids to the growing end of a polypeptide chain during translation. R.Holly in 1965 gave clover leaf model of tRNA for yeast alanyl tRNA. It has four major sites - AAbinding site, anticodon, site, TUC loop and DHU loop. The chain is having unpaired base sequence CCA at 3' end and G at 5' end.
