The Cell Cycle

Question 1

G1 phase

Answer 1

INTERPHASE: the cell duplicates its organelles and cytosolic components

Question 2

S phase

Answer 2

INTERPHASE: DNA is replicated and each chromosome replicates to form 2 sister chromatids held at a centromere

Question 3

G2 phase

Answer 3

INTERPHASE: enzyme & protein synthesis occurs, ATP is produced in large amounts and centrioles replicate.

Question 4

Prophase

Answer 4

MITOSIS: separates duplicated genetic material into two daughter cells. Chromatin coils and forms chromosomes. Mitotic spindle begins to form.

Question 5

Metaphase 1

Answer 5

MITOSIS: the allignment of chromosomes at the center of the cell by pulling/pushing. 2 kinetochores of each chromosome attaches to microtubules from the opposite spindle poles

Question 6

Anaphase 1

Answer 6

MITOSIS: sister chromatids seperate from eachother and are pulled toward opposite ends of the cell. The spindle disappears and nuclear membrane reforms

Question 7

Telophase 1

Answer 7

MITOSIS: mitotic spindle is broken down into its building blocks. The chromosomes begin to recondense and return to their “stringy” form

Question 8

Cytokinesis

Answer 8

the division of the cytoplasm to form two new cells, each with a complete set of chromosomes identical to the parent cell
