Sentences with phrase «particular codons»

This tiny change in fitness is big enough for evolution to select the «fittest» DNA sequence and causes what is called «codon usage bias» — the widespread use of particular codons to make highly expressed proteins.

Brandis and Hughes asked whether it mattered which particular codons were used to make EF - Tu, one of the most important proteins in Salmonella.

Theoretically, once a particular codon — say, TAG — has been removed from a genome, the cell's protein - making machinery could be reprogrammed to assign TAG to an amino acid, instead of being a stop signal.

Not exact matches

Scientists have noted previously that some people seem less susceptible to prion diseases if they have an amino - acid substitution in a particular region of the prion protein — codon 129.

Each codon directs a particular amino acid to be added to a protein chain.

Because each tRNA is specific for a single amino acid, it must be able to recognize the codon on the mRNA that codes for that particular amino acid.

We furthermore show that several of these RNA modifications have a dynamic response to environmental stress and that, in particular, changes in the tRNA wobble base modification 5 - methoxycarbonylmethyl -2-thiouridine (mcm (5) s (2) U) lead to codon - biased gene - expression changes in starved animals.

From these models, it is easy for students to visualise how a set of three base pairs from a messenger RNA molecule (codon) matches with a particular amino acid.
