The overall role of tRNA in protein synthesis is to decode a specific codon of mRNA, using its anticodon, in order to transfer a specific amino acid to the end of a chain in the ribosome. Many tRNAs together build upon the amino acid chain, eventually creating a protein for the original mRNA strand.
What is the function of tRNA carry genetic instructions?
transfer RNA (tRNA) – a type of RNA that is folded into a three-dimensional structure. tRNA carries and transfers an amino acid to the polypeptide chain being assembled during translation. translation – the process in which a cell converts genetic information carried in an mRNA molecule into a protein.
What happens to the amino acids that were attached to tRNA?
When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain. Then the tRNAs and ribosome continue to decode the mRNA molecule until the entire sequence is translated into a protein.
What is the function of tRNA?
= Transfer RNA (tRNA) is a small RNA molecule that participates in protein synthesis. Each tRNA molecule has two important areas: a trinucleotide region called the anticodon and a region for attaching a specific amino acid.

How do tRNAs act as intermediaries in translation?
In this way, they act as the intermediaries between nucleotide and amino acid sequences. tRNAs are ribonucleic acids and therefore capable of forming hydrogen bonds with mRNA. Additionally, they can also form ester linkages with amino acids, and therefore, can physically bring mRNA and amino acids together during the process of translation.
What is the function of the threonine loop in tRNA?
It is present between the TΨC loop and the anticodon loop. Its size varies from 3-21 bases. It helps in the recognition of the tRNA molecule. It plays an important role in protein synthesis. It acts as an adapter molecule for linking amino acids to its specific codon present in mRNA.
