Solution
The correct option is B Codon on mRNA All tRNAs have about 73 to 93 nucleotide that fold into four base-paired stems and three loops. The 3' end has CCA sequence. Attachment of an amino acid to the 3 adenosine yields an aminoacyl-tRNA. Transfer-RNA has 7-15% post-transcriptionally modified bases. Dihydrouridine (D) is nearly always found in the D loop and ribothymidine (T) and pseudouridine in the T psi C loop. The D loop serves as aminoacyl synthetase recognition and binding loop while the T psi C loop binds the charged tRNA-amino acid to ribosome. The anticodon loop has triplet at the tip which base pairs with the corresponding codon in mRNA. Correct answer is B.
