Zoology - Molecular Basis of Inheritance Question with Solution | TestHub

$tRNA$has an anticodon loop which has anticodons complementary to the codons of$mRNA$. Due to very small size,$tRNA$is also called soluble$RNA$. Amino acid binds to 3' end of$tRNA$. The cloverleaf model shows the basic plan of tRNA secondary structure or 2D structure. Three-dimensional structure shows an inverted L–shaped configuration.

There are three loops in tRNA:
i) Aminoacyl synthetase binding loop or DHU loop (dihydroxyuridine loop): 1st loop from 5’ end.
ii) Ribosomal binding loop with 7 unpaired bases: It is 1^stloop from 3’ end, also called loop.
iii) Anticodon loop with 7 unpaired bases. Out of the 7 bases in the anticodon loop, 3 bases act as anticodon for a particular triplet codon present on mRNA.
