Question

In any given species, there are at least how many types of aminoacyl tRNA synthetases? a. 20

b. 40

c. 100

d. 200

Short answer

There is at least one type of amino-acyl tRNAsynthetase for every 20 amino acids in a given species.

Step-by-step solution

step-1: Introduction

A tRNA-ligase, also known as an aminoacyl-tRNA synthetase (aaRS or ARS), is an enzyme that connects the proper amino acid to its associated tRNA.

step-2: Explanation of correct answers

Option (a) 20. The amino-acyl tRNA synthetase enzyme is in charge of the tRNA charging process, which connects the tRNA molecule to the appropriate amino acid. In general, this enzyme is present in at least one group for each of the 20 amino acids. This number may vary by species, but it must be at least 20 for any species to be considered.

step-3: Explanation of incorrect answers

Option (b) 40 is an alternative to option (a). The amino-acyl synthetase enzyme is responsible for the production of 20 amino acids by mRNAs throughout the transcription and translation process. As a result, all species has at least 20 amino acids, which may vary depending on the species.

Option (c) is worth a hundred dollars. The amino-acyl synthetase enzyme is responsible for the production of 20 amino acids by mRNAs throughout the transcription and translation process. As a result, all species has at least 20 amino acids, which may vary depending on the species.

Option (d) 200 is a good choice. The amino-acyl synthetase enzyme is responsible for the production of 20 amino acids by mRNAs throughout the transcription and translation process. As a result, all species has at least 20 amino acids, which may vary depending on the species.
