Question

Explain the roles of mRNA and tRNA in protein synthesis.

Answer 1

Ribosomal RNA(rRna) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into proteins chains. They also bind tRNAs and various accessory molecules necessary for proteins synthesis

Answer 2

Answer: Below is the explanation

Explanation:

Transfer RNA (tRNA) molecules transport amino acids to the ribosomes during protein synthesis, while messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis. Ribosomal RNA (rRNA) molecules make up the core of a cell's ribosomes, which are the structures in which protein synthesis occurs.

Each class of RNA in eukaryotic cells has its own polymerase, whereas in prokaryotic cells, each class of RNA is synthesised by a single RNA polymerase.

Although they appear to serve regulatory roles in gene expression and be engaged in defence against invading viruses, other forms of RNA exist as well but are less well understood.
