WebMar 5, 2024 · Lack of genetic variation increases the risk of extinction. Without variety, there may be no organisms that can survive a major change in the environment. Prokaryotes have a different way to increase genetic variation. ... Genetic transfer makes bacteria very useful in biotechnology. It can be used to create bacterial cells that carry new genes. WebThey do have ribosomes because they have to code for proteins just like the rest of us do. Some of those proteins, they'll make some from-- bacteria, they'll make these flagella, which are tails that allow them to move around. They also have these things called pili.
