Question

select all of the following that are functions of mitosis.
a. shuffle the genetic material
b. produce four daughter cells from one parent cell
c. growth and repair of body tissues
d. produce daughter cells that are genetically identical
e. produce two daughter cells from one parent cell
which of the following represents the correct order of the phases of mitosis?
a. prophase, metaphase, anaphase, telophase
b. metaphase, prophase, telophase, anaphase
c. prophase, anaphase, metaphase, telophase
d. metaphase, anaphase, prophase, telophase

Explanation:

First Question (Select all functions of mitosis)

• Option A: Shuffling genetic material is done in meiosis (crossing over), not mitosis. So A is incorrect.
• Option B: Mitosis produces 2 daughter cells, meiosis produces 4. So B is incorrect.
• Option C: Mitosis is involved in growth (e.g., in embryos, tissue expansion) and repair (replacing damaged cells) of body tissues. So C is correct.
• Option D: Mitosis results in daughter cells with the same genetic material as the parent (genetically identical), as there's no recombination. So D is correct.
• Option E: Mitosis divides one parent cell into two daughter cells. So E is correct.

The phases of mitosis occur in the order: Prophase (chromosomes condense, nuclear envelope breaks), Metaphase (chromosomes align at equator), Anaphase (sister chromatids separate), Telophase (nuclear envelopes reform, chromosomes decondense). So the correct order is Prophase, Metaphase, Anaphase, Telophase.

Answer:

C. Growth and repair of body tissues, D. Produce daughter cells that are genetically identical, E. Produce two daughter cells from one parent cell
