Sentences with phrase «letter codon»

Once organisms began to flourish with three - letter codons, Benner said, it became hard for anything that deviated from that system to compete.

Playing with the parameters that define the natural genetic code — four nucleotide bases, three - letter codons, 20 amino acids — leads back to questions raised decades ago about how that code evolved and whether it is optimal.

Not exact matches

When cells activate a gene to make protein, their genome spells out three - letter words known as codons.

There are 64 ways of combining the four letters (U, A, G and C) into groups of three, and 61 of these codons are used to encode the 20 amino acids found in nature.

Then the cell's protein - production machinery, the ribosome, reads the four letters of the RNA code in sets of three letters called codons.

Three - letter genetic sequences are known as codons, and they can either code for an amino acid — the building blocks of proteins — or act as stop signals.

Basically, the cell's protein - making machinery reads a sequence of DNA as a sentence composed entirely of three - letter words called codons.

Even codons for different amino acids that have two of their three letters in common tend to translate into amino acids that share key chemical properties.
