What are the functions of the different types of RNA molecules?
Homework Answers
there sre three types of RNA molecule namely mRNA, tRNA, rRNA
1. mRNA: Messanger RNA:
This is the RNA molecul;e which is main for tranlation into protein. The information in the form of codons in the mRNA is decoded into amino acids and form the protein . Synthesis of all the proteins in prokaryotes and Eukaryotes in not possible without mRNA.
tRNA : it is called Transfer RNA : This RNA ois the key molecule which deciphers the amino acid against Codons in the mRNA. tRNA is different for all separate amino acids. tRNA is higly specific in its functioning.
rRNA: This is the RNA molecule which assembles for the protein synthesis, and catalyse the assembly of amino acids to form a polypeptide chain. There are two subunits, amsll subunit and large subunit of ribosome. When small subunit binds with mRNA then large subunits assemble with site for amino acid and peptide bond formation. Both the subunits have their own set of rRNA molecules.

Transfer RNA molecules are short RNA sequences (on average around 78 nucleotides long) that form a stem-and-loop structure, where one of the loops carries the anticodon that binds with the appropriate codon in the messenger RNA. At least 30 different tRNA genes are required by each cell to specify translation, but each of these tRNA genes can occur in multiple copies in a single genome, often co-located in clusters. How might these features of tRNA structure and function influence the...
