Shape of 3-D view of tRNA is
Open in App
Solution
The correct option is D L-shaped
All tRNAs have about 73 to 93 nucleotides 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 the ribosome. The anticodon loop has triplet at the tip which base pairs with the corresponding codon in mRNA. The tertiary structure of tRNA is a compact "L" shaped in which anticodon stem and acceptor stem form a double helix. The correct option is D.
