A few question almost plasmids surrounded by microbes?
Hi,
1- I know that plasmids can be transferred from a bacteria to another, but can it be from one specie to whole diffrent one? (let's say e.coli to stepptococcus)
2- When a bacteira have a plasmid, and then multiplies, will that plasmid go to the new germs (and so on, meaning to all the bacterias descending from that first one will have it?)
3- Can a plasmid be lost after a while if it's not adjectives (when no need for antibiotic resistnace for example)
Answers:
They can be transferred between species. For example the F plasmid can just transferred between species through a "sex pilus". Also if a bacteria dies, other germs can pick up certain parts of the dead bacteria's genetic code, which is sometimes how resistance can be passed.
If the plasmid integrates itself into the bacteria's genes to multiply itself, it can be passed on to descendants of that bacteria. however, if the plasmid leaves minus making a copy of itself, then that bacteria doesn't have the plasma and it's descendants won't any.
Plasmids technically can't be lost, but again, if it transfers itself to another bacteria without making a copy of itself, the first bacteria will no longer own those genes
