The 25-bp insertion causes a frameshift mutation and creates stop codons in all three reading frames. |
This frameshift mutation could be merely drifting to high frequency due to weak functional constraint. |
Arrows indicate the position of the point mutation and the corresponding nucleotide on the wild-type sequence. |
We are studying properties of spontaneous mutation affecting quantitative traits of the annual crucifer, Arabidopsis thaliana. |
We estimate that reversion of the lac mutation is about one-tenth as likely as a null frameshift mutation in a typical gene. |
The plant and seed pigmentation components can be lost independently by mutation or unequal crossing over, leading to different derivatives. |
