Trna in a sentence

The ribosome contains three RNA binding sites, designated A, P and E. The A site binds an aminoacyl-tRNA; the P site binds a peptidyl-tRNA (a tRNA bound to the peptide being synthesized); and the E site binds a free tRNA before it exits the ribosome.

The coupling reactions are catalysed by a group of enzymes called aminoacyl-tRNA synthetases (named after the reaction product aminoacyl-tRNA or aa-tRNA).

The duplicated tRNA type can compensate because it is able to perform, at a lower rate, the codon-amino acid matching function of the eliminated tRNA type.

The enzyme aminoacyl tRNA synthetase "charges" the tRNA molecules with the correct amino acids.

The gene for tRNA- formylmethionine (tRNA-fmet) is also encoded in the plastid genome and is required for translation initiation in both plastids and mitochondria.

The genes encoding tRNA-Glu and tRNA-fmet, however, appear to be indispensable.

They also found that the accumulation of the peptidyl-tRNAs inhibited the in yeast lacking peptidyl-tRNA hydrolase, an essential cellular enzyme.

Organisms carry many types of tRNAs, each encoded by one or more genes (the tRNA gene set).

Amino acid activation refers to the attachment of an amino acid to its Transfer RNA (tRNA).

Amino acids are selected, collected, and carried to the ribosome by transfer RNA (tRNA) molecules, which enter one part of the ribosome and bind to the messenger RNA chain.

Aminoacyl transferase binds AMP-amino acid to tRNA.

A plastid is required to continue expressing the gene for tRNA-fmet so long as the mitochondrion is translating proteins.

Each of the 20 amino acids are recognized by its specific aminoacyl-tRNA synthetase.

Each ribosome is divided into two subunits: 1. a smaller subunit which binds to a larger subunit and the mRNA pattern, and 2. a larger subunit which binds to the tRNA, the amino acids, and the smaller subunit.

In between a grouping of five tRNA genes, a sequence resembling vertebrate origin of light strand replication is found.

It, however, requires a five base binding between the mRNA and tRNA with a flip of the anti-codon creating a triplet coding, even though it is a five-base physical interaction.

Mechanism of action Tetracycline inhibits protein synthesis by blocking the attachment of charged aminoacyl-tRNA to the A site on the ribosome.

RNA is transcribed in the nucleus ; once completely processed, it is transported to the cytoplasm and translated by the ribosome (shown in very pale grey behind the tRNA).

Shortly thereafter, Robert W. Holley determined the structure of transfer RNA (tRNA), the adapter molecule that facilitates the process of translating RNA into protein.

Similarly, tRNA is suggested to have evolved from RNA molecules that began to catalyze amino acid transfer. citation RNA in information storage RNA is a very similar molecule to DNA, and only has two chemical differences.
