WebA transfer RNA ( tRNA) is a special kind of RNA molecule. Its job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular "bridge" between the two. Each tRNA contains a set of three nucleotides called an anticodon. The … Each tRNA has an anticodon, a set of three nucleotides that binds to a matching … WebThe rapid peptide transfer occurs after the accommodation of the incoming tRNA in the A site [149,150,151,152], leading to the formation of the so-called pre-translocational complex, ready to translocate the tRNA-mRNA complex by one codon in the 5' to 3' direction once unlocked [153,154].
TRNA - definition of tRNA by The Free Dictionary
WebThe actual job of ferrying the amino acids to the ribosome is done by another type of RNA, called transfer RNA, or tRNA. tRNA is a very short RNA sequence that is specialized for finding a specific type of amino acid within the cytosol, and bringing it to the ribosome. WebThe ribosome will read the nucleotide sequence from the 5' to 3' direction on binding to an mRNA and synthesises the corresponding protein from amino acids in an N-terminal (amino-terminal) to C-terminal (carboxyl-terminal) direction.
