Here's why:
* Structure: tRNA is a single-stranded RNA molecule, just like messenger RNA (mRNA) and ribosomal RNA (rRNA). It has a characteristic cloverleaf structure with specific regions responsible for its functions.
* Function: Like other RNA molecules, tRNA plays a crucial role in protein synthesis. It acts as a carrier, bringing specific amino acids to the ribosome to be incorporated into the growing polypeptide chain.
* Chemical Composition: tRNA, like all RNA molecules, is composed of a chain of nucleotides linked together by phosphodiester bonds. These nucleotides contain the sugar ribose and the bases adenine (A), guanine (G), cytosine (C), and uracil (U).
Therefore, the name "transfer RNA" is descriptive of its function, while "RNA" reflects its chemical nature and its membership within the broader class of ribonucleic acids.
