Question

A circular bit of DNA that replicates independent of a bacterium’s chromosome is called a /an _____. It has been used to slip a non-bacterial gene into a bacterium, which will cause the bacterium to make a chemical that we want?

Answer 1

Answer:

The correct answer will be-Plasmid

Explanation:

Plasmids are the extra-circular chromosomal segments present in the bacteria which provides very important functions to the bacteria.  

The plasmid contains many important genes like the gene to provide resistance against antibiotics and genes for transfer to other bacteria and many others.

The plasmid contains their own origin of replication due to which they can replicate on their own irrespective of the replication of the circular bacterial chromosome.

Thus, the plasmid is the correct answer.
