Transfer-messenger RNA (tmRNA) Definition, Structure, Properties

What is Transfer-messenger RNA (tmRNA)? Transfer-messenger RNA (tmRNA), also known as 10Sa or SsrA RNA, is exceptional among bifunctional RNAs in that it possesses both tRNA and mRNA characteristics. tmRNA employs these two activities to liberate translationally stalled ribosomes and to target nascent polypeptides for destruction. This coordinated reaction, known as trans-translation, helps to bacterial … Read more

Small nuclear RNA (snRNA) - Structure, Types, Definition

What is Small nuclear RNA (snRNA)? Small nuclear RNA (snRNA) is a small RNA with an average length of 150 nucleotides. A variety of noncoding RNAs are encoded by eukaryotic genomes, and snRNA is a kind of highly abundant, nucleus-localized RNA with essential roles in intron splicing and other RNA processing. In order to mediate … Read more
