Question

How does recombination in bacteria differ from recombination in eukaryotes?

Options:
a) Involvement of RecA protein
b) Occurrence during meiosis
c) Use of plasmids for recombination
d) Dependence on crossing over

Answer 1

Recombination in bacteria differs from recombination in eukaryotes in terms of the involvement of RecA protein, the use of plasmids for recombination, occurrence during meiosis, and dependence on crossing over.

Step-by-step explanation:

Recombination in bacteria differs from recombination in eukaryotes in several ways:

1. Involvement of RecA protein: Recombination in bacteria involves the RecA protein, which assists in the repair of DNA damage and promotes the exchange of genetic material.
2. Use of plasmids for recombination: Bacteria can exchange genetic material through plasmids, small circular DNA molecules that can move between cells. This is not typically seen in eukaryotes.
3. Occurrence during meiosis: Recombination in eukaryotes primarily occurs during meiosis, the process of creating gametes. In contrast, bacteria can undergo recombination during different phases of their reproductive cycle.
4. Dependence on crossing over: In eukaryotes, crossing over during meiosis is a key mechanism for genetic recombination. This process involves the exchange of genetic material between homologous chromosomes. Bacteria, however, have different mechanisms for genetic transfer and recombination.
