In mitosis, cohesin dissolves during _________, allowing sister chromatids to separate.

a. Prometaphase

b. Metaphase

c. Anaphase

d. Cytokinesis

Expert Solution

The correct answer is option c. Anaphase

The cell division that takes place in the eukaryotic cells is mitosis. In mitosis, the nucleus divides and produce two daughter cells which is same or identical to the parent cell. The cell cycle consists of intraphase, mitosis and cytokinesis . There are four stages of mitosis which includes prophase, metaphase, anaphase and telophase. Anaphase is the third stage of mitosis. In anaphase, the chromatid arms gets seperated and move to the opposite ends of cell. The cohesin gets dissolved and sister chromatids moves apart. Cohesin is a protein that holds the chromatids together. It gets dissolved during the anaphase.

Option a. Prometaphase is not the right answer because in this phase, the nuclear envelope gets dissolved and the spindle fibres gets attached to chromosomes.

Option b. Metaphase is not the right answer because in this phase, the chromosomes will arranged at the middle. Metaphase is the second phase in mitosis.

Option d. Cytokinesis is not the right answer because in cytokinesis, the cytoplasm will divides and forms two daughter cells.

A) Formulate a one sentence hypothesis which states which stages of mitosis (prophase, prometaphase, metaphase, anaphase, or telophase) will be most common to the least common. Note: A hypothesis should be written as a statement (claiming something to be true). Additionally, a hypothesis must be testable experimentally. B) Describe your rationale for your hypothesis. Do you think all stages will have equal counts? Why or why not? If not, which stage of mitosis do you think will be most, least,...
