What is the specific function of tRNA?

Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.

What are the two functional regions of tRNA?

Each tRNA molecule has two important areas: a trinucleotide region called the anticodon and a region for attaching a specific amino acid.

Is tRNA a specific codon?

Each tRNA is designed to carry a specific amino acid that it can add to a polypeptide chain. This order is determined by the attraction between a codon, a sequence of three nucleotides on the mRNA, and a complementary nucleotide triplet on the tRNA, called an anticodon.

Which amino acids are tRNA specific?

At one end, the tRNA has an anticodon of 3′-UAC-5′, and it binds to a codon in an mRNA that has a sequence of 5′-AUG-3′ through complementary base pairing. The other end of the tRNA carries the amino acid methionine (Met), which is the the amino acid specified by the mRNA codon AUG.

What is the main function of tRNA in protein synthesis?

Functions of RNA in Protein Synthesis

Table 1. Structure and Function of RNA
	mRNA	tRNA
Function	Serves as intermediary between DNA and protein; used by ribosome to direct synthesis of protein it encodes	Carries the correct amino acid to the site of protein synthesis in the ribosome

What is the main function of tRNA is relation to protein synthesis?

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 are the two steps of protein synthesis called?

Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.

What is the function of tRNA in protein synthesis?

Molecules of tRNA are responsible for matching amino acids with the appropriate codons in mRNA. Each tRNA molecule has two distinct ends, one of which binds to a specific amino acid, and the other which binds to the corresponding mRNA codon.

What is the function of tRNA Quizizz?

What is the function of transfer RNA? It is a part of the ribosome. It bonds to other RNA molecules, leading to their destruction. It delivers the correct amino acid to the ribosome.

How is the dual specificity of tRNA determined?

Dual specificity refers to the fact that each tRNA has its particular anticodon, which corresponds to the specific amino acid to which it can be bonded. The anticodon and the 3′ end (or “tail”)of each tRNA determine its “dual” specificity.

What happens when tRNA is added to a protein?

During translation, each time an amino acid is added to the growing chain, a tRNA molecule forms base pairs with its complementary sequence on the messenger RNA (mRNA) molecule, ensuring that the appropriate amino acid is inserted into the protein. Transfer RNA is that key link between transcribing RNA and translating that RNA into protein.

What are the two regions of a tRNA molecule?

Each tRNA molecule has two important areas: a trinucleotide region called the anticodon and a region for attaching a specific amino acid.

What is the role of the T-arm in tRNA recognition?

The T-arm is involved in the interaction of tRNA with the ribosome. Finally, a variable arm containing less than 20 nucleotides is situated between the anticodon loop and the T-arm. It plays a role in AATS recognition of tRNA, but could be absent in some species .
