mitosis and cell cycle

What are the three main concepts related to cell division discussed in the source?

cell theory, mitosis vs. meiosis, and mitosis vs. apoptosis.

Briefly describe what happens to DNA during the S phase of Interphase

During the S phase of Interphase, the cell grows and DNA replication occurs.

What is the role of the G1 checkpoint in the cell cycle?

The G1 checkpoint is a main checkpoint where the cell can go through apoptosis if the DNA is damaged.

During which phase of mitosis do the sister chromatids separate and move to opposite poles?

The sister chromatids separate and move to opposite poles during Anaphase.

What is the primary function of the spindle apparatus during mitosis?

The spindle apparatus attaches to and moves the chromosomes during mitosis.

In which phase of mitosis do the chromosomes align at the center of the cell?

The chromosomes align at the center of the cell during Metaphase.

What are telomeres, and what happens to them after each cell division?

caps at the end of chromosomes, they become shorter after each cell division.

Why are the daughter cells produced by mitosis considered genetically identical to the parent cell?

the duplicated chromosomes are split equally into the two new cells.

Name two functions of mitosis in an organism.

growth and wound repair (other valid answers include development and tissue maintenance).

What occurs during cytokinesis?

the parent cell is cut in half to form the two daughter cells.
