Q

Give one similarity and one difference between the bacteria cell and an animal cell.

A

Similarity- they both contain a cell membrane and ribosomes
Differences- bacteria cells don’t contain a nucleus to hold DNA, animals do.
Animal cells don’t have a flagellum or a cell wall, bacterial cells

Q

Where’s plasmid DNA found in the bacteria cell and what’s it’s function?

A

It’s found in the cytoplasm in small closed-circles and can move from one bacterium to another giving variation.
