What determines if a bacteria has an F-plasmid? Are F-plasmids the only plasmids shared between bacteria?

If I’m designing an expierment to study bacterial concergation (while adding a plasmid of my choice to the bacteria), how do I know the bacteria I’m using has an F-plasmid (or can transfer my ...

How taking up plasmids on heat shock evolutionary advantageous to bacteria?

During the transformation protocol we apply heat shock to bacteria to make them take up plasmids from their environment. It is really useful in the lab. However, it presents an evolutionary paradox ...

Do archaea undergo the same horizontal gene transfer processes as bacteria?

Do archaea also undergo processes like conjugation, trasformation, etc.? If not, do they have their own horizontal gene transfer methods? Can bacteria conjugate with archaea?

Why Hfr cells are called high frequency recombination cells?

I understand that Hfr cells are formed when fragment of bacterial plasmid integrates itself in another bacteria's (host) genome through homologous recombination but my question is why do we call these ...

Why are there different species of bacteria?

The usual (high school or intro to bio) explanation for diversification of species comes from multicellular, usually sexually reproducing organisms, and seems to be closely tied to the biological ...

Virus-to-virus gene transfer via “sequences integrated into a common host organism”

From "Risks from GMOs due to Horizontal Gene Transfer", by Paul Keese: In addition to direct HGT between organisms as depicted in Figure 1, forms of indirect HGT have been observed, which involve ...

Can an organism obtaining a part of its genome via horizontal gene transfer be called a “hybrid”?

Wikipedia definition of "hybrid" offers many competing definitions. But most seem to be centered on sexual-reproduction gene transfer. Is there an official (in a textbook or widely accepted peer ...

What advantage would the initial 'donor' in horizontal gene transfer by conjugation have received?

I am struggling to think why horizontal gene transfer between bacteria would have persisted during the course of evolution as surely it puts the 'donor' at a disadvantage? For example, consider a ...
