What iswrong with this explanation of how
bacteriaevolved resistance to penicillin?
When bacteria first came intocontact with
penicillin, many werekilled by the antibiotic, but some were able
to adapt by evolving aresistance to it. These survived and passed
on their resistance totheir offspring. In that way, bacteria
acquired resistance topenicillin.

Answer:

When bacteria are exposed to an antibiotic, such as penicillin, they often mutate.

Explanation:

This means that part of their DNA changes, giving the antibiotic resistance to the bacteria.

In this way, the bacteria can generate a copy of their DNA and transmit it to their offspring, giving their resistance.

On other occasions, a resistant bacterium dies from causes unrelated to the antibiotic, leaving its DNA free.

If other bacteria manage to capture that DNA, it will also acquire antibiotic resistance.
