Question

Match each recognition process with its appropriate description:

A) Recognition of an aminoacyl tRNA synthetase for its cognate tRNA
B) Recognition of an aminoacyl tRNA synthetase for its cognate amino acid
C) Recognition of a charged tRNA for its cognate codon in mRNA

And, for each of these recognition processes, match them with the corresponding description:

a) A - Recognition of an aminoacyl tRNA synthetase for its cognate tRNA
b) B - Recognition of an aminoacyl tRNA synthetase for its cognate amino acid
c) C - Recognition of a charged tRNA for its cognate codon in mRNA

Select the correct pairs:
A) a - B, b - A, c - C
B) a - A, b - B, c - C
C) a - C, b - B, c - A
D) a - B, b - C, c - A

Answer 1

The correct answer is B) a - A, b - B, c - C, matching each recognition process with its description for aminoacyl tRNA synthetases, tRNAs, and their interaction with codons in mRNA.

Step-by-step explanation:

The correct pairs for each recognition process with its appropriate description are: A) a - Recognition of an aminoacyl tRNA synthetase for its cognate tRNA, B) b - Recognition of an aminoacyl tRNA synthetase for its cognate amino acid, C) c - Recognition of a charged tRNA for its cognate codon in mRNA. So, the correct option that matches these descriptions is B) a - A, b - B, c - C.

Aminoacyl tRNA synthetases are enzymes that link tRNA molecules to the correct amino acids. This process, known as tRNA 'charging', involves the enzyme first activating an amino acid by binding it with AMP and then transferring the activated amino acid to its corresponding tRNA, forming a charged tRNA that is ready for protein synthesis. The anticodon of tRNA recognizes and pairs with the complementary codon in mRNA to ensure the correct amino acid sequence is formed during protein synthesis.
