Sentences with phrase «exchange gene segments»

It has multiple hosts and can evolve by mutation but also reassortment (when two closely related strains infect the same host and exchange gene segments, producing new strains — a process distinct from mutation, when the RNA of a virus is miscoded during replication).

Not exact matches

The researchers also suggest that because the Y can not exchange genes with the X chromosome anymore, it uses other unusual ways to reconfigure its DNA, such as recombining with itself to add on new segments of identical DNA — or palindromes — into its genome.

Background mutation rates by this method is ∼ 1 base - exchange per 1,000 bases sequenced (based on sequences of constant region gene segments).
