What are the roles of mRNA, tRNA, and rRNA in translation?

Answer

The roles of mRNA, tRNA, and rRNA in translation are to carry the genetic code, bring amino acids, and form the ribosome structure, respectively.

Solution

a

mRNA (messenger RNA): Carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis

b

tRNA (transfer RNA): Transports the appropriate amino acids to the ribosome and matches them to the coded mRNA message through its anticodon during protein synthesis

c

rRNA (ribosomal RNA): Combines with proteins to form ribosomes, which are the sites of protein synthesis. rRNA ensures the proper alignment of mRNA and tRNAs and catalyzes the formation of peptide bonds between amino acids

Key Concept

Translation involves mRNA, tRNA, and rRNA working together to synthesize proteins.

Explanation

mRNA provides the template, tRNA brings in amino acids, and rRNA forms the core of the ribosome's structure and catalytic activity.
