Results from our forumRe: The Colin Leslie Dean species paradox... are in a seperate domain from protists, fungi, plants and animals. They ingest plasmids and are infected by viruses. Thus they have insertions, deletions and replacement of their DNA. Some of them revert back and are called revertants. SO because they change in their genetic material and in ...

Re: Natural selection is proven wrong... aren't deleterious enough to disappear completely - if viewed on a species level. Finally, some of the conditions are caused by point mutations, deletions, chromosomal translocation or invertion, and as such are results of random events on a genomic scale. They are not inherited from anywhere, ...

virology... cell. Oncogene come into play, when viral genome of many retroviruses that transform cells. An oncogenic gene in retroviruses is the sarcoma gene, deletions or even mutations in the src gene demolish transformation and tumor promotion. Other than src, there are many other types of oncogenes. Overall, ...

Gene activation?... (but are not limited to): -Point mutations (see c-kit) -Insertions of foreign genetic elements in coding/regulatory sequences of proto-oncogenes -Deletions -Looking at them the wrong way...well ok maybe not that last one You can also have oncogenes imported into the cells through viruses. Example ...

Re:... to be very important in gene acquisition and quite frequent now that we can see whole genomes. There are also gene duplications. So it's not just deletions and point mutations. -I have witnessed and selected many "beneficial" mutations in bacteria. They are individually not very frequent, ...
