Correct Option: A
The Shine-Dalgarno sequence is a ribosomal binding site in the mRNA. The leucine zipper is a three dimensional structural motif in proteins. These motifs are usually found as part of a DNA-binding domain in various transcription factors, and are involved in regular gene expression. Aminoacyl tRNA synthetase is an enzyme that catalyzes the esterification of a specific amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl tRNA. RNAi works for the gene silencing (Small interfering RNA is mainly used in gene silencing and Antisense technology).
