Question

Which one is correct about reproduction in bacteria?

• A. Spores are formed under unfavorable conditions
• B. Mainly by binary fission
• C. Sexual reproduction by transfer of DNA from one to another
• D. All of the above

Answer 1

The correct option is D

All of the above

The correct option is D.

Explanation for Correct option:

1. Binary fission is a form of reproduction used by bacteria.
2. During binary fission, the chromosome duplicates itself, resulting in two identical genetic copies. The cell then divides into two daughter cells as it develops in size.
3. Both the parent and daughter cells have the same DNA.
4. Binary fission can happen in a matter of seconds.
5. Organisms reproduce asexually with the help of spores.
6. Spores are generated in bacteria as well, however, bacterial spores are rarely used for reproduction.
7. These spores are latent and function as a barrier between bacteria and harsh environmental conditions.
8. During conjugation, DNA is exchanged between bacteria.
9. After the donor cell uses a pilus to pull itself close to the recipient cell, DNA is exchanged between them.

Final answer: Spores are formed under unfavorable conditions, Mainly by binary fission, Sexual reproduction by transfer of DNA from one to another are all correct about reproduction in bacteria
