miRNAs, tRNAs, and rRNAs all do not code for proteins.
Eukaryotic miRNA (21-22 nt) is responsible for RNA interference (RNAi). Enzymes are used by miRNA to help break down complementary mRNA.The mRNA could be prevented from being translated or degraded more quickly as a result of this.
The smallest of the three RNA types, tRNA has between 75 and 95 nucleotides. The transfer of amino acids during protein synthesis is the primary function of tRNAs, which are an essential component of translation. As a result, they are referred to as transfer RNAs.
rRNAs consolidate with proteins and compounds in the cytoplasm to shape ribosomes, which go about as the site of protein amalgamation. During translation, these intricate structures facilitate the assembly of amino acids into a polypeptide chain by traveling along the mRNA molecule. They communicate with tRNAs and other molecules that are necessary for the synthesis of proteins.
