A) tRNA – It is called transfer RNA, soluble RNA or sRNA. It constitutes about 15% of the total RNA. It is the smallest or short stable RNA consisting of 70-85 nucleotides. It acts as an adaptor molecule that is meant for transferring amino acids to the ribosome for the synthesis of the polypeptide.

Is tRNA long lived?

Due to its long half-life compared to messenger RNA, bacterial transfer RNA is known as stable RNA. ... Degradation of the majority of cellular tRNA occurs within twenty minutes of the onset of starvation for each of several amino acids.

Is tRNA short or long?

Transfer RNA (tRNA) is a short nucleotide RNA chain. With a L-shaped structure, tRNA functions as an 'adaptor' molecule that translates three-nucleotide codon sequence in the mRNA into the suitable amino acid of that codon.
