Question

question 3
bacteria are unable to do mitosis, because

a only eukaryotes do cytokinesis
b they only reproduce using meiosis
c prokaryotes lack a cell cycle
d mitosis is nuclear division

question 4
the process during which the nucleus of a cell is divided into two nuclei is known as
a mitosis
b cytokinesis
c g1
d s phase

Explanation:

• Question 3:
• Mitosis is a form of nuclear division. Bacteria are prokaryotes. Prokaryotes do not have a true nucleus. So, they cannot perform mitosis (which is nuclear division).
• Option a is incorrect because prokaryotes (like bacteria) do a form of cytokinesis (binary - fission involves cytoplasmic division).
• Option b is incorrect because bacteria reproduce by binary - fission (asexual, not meiosis which is for sexual reproduction in eukaryotes).
• Option c is incorrect because prokaryotes have a cell cycle (though different from eukaryotes).
• Question 4:
• Mitosis is the process where the nucleus of a cell is divided into two nuclei.
• Cytokinesis is the division of the cytoplasm.
• G1 is a phase in the cell cycle (growth phase 1) and S - phase is the phase of DNA synthesis in the cell cycle.

Answer:

• Question 3: d. mitosis is nuclear division
• Question 4: a. mitosis
