Answer 9

S (Synthesis)

Question 10

Preparation for cell division

Answer 10

G1 (Gap 1) phase

Question 11

-cell grows rapidly
-cell prepares for the actual cell division
-Cell matures

Answer 11

G2 (Gap 2) Phase

Question 12

Longest phase of mitosis

Answer 12

Prophase

Question 13

The chromosome can be clearly seen to consist of a pair of sister
chromatids joined at the centromere. Chromatid is one of the two identical “sister”
parts of a duplicated chromosome. The nucleolus disappears and the nuclear
membrane starts to break down. The spindle microtubules start to form from the
centrosomes moving towards the opposite poles. The chromatids are now attached
to the spindle microtubules. They start pulling the chromosomes toward the center
of the cell ready for the next step

Answer 13

Prophase

Question 14

Chromosomes are aligned at
the middle of the cell. All the chromosomes are attached to the spindle microtubules
which are now fully developed. The nuclear membrane has broken. The centrosomes
are located at the opposite poles.

Answer 14

Metaphase

Question 15

The sister chromatids separate from their partners. Each chromatid is now
considered a daughter chromosome. Microtubules attached to the centromere are
shortened bringing the chromosomes toward the opposite poles. While microtubules
not attached to the chromosome grow longer, pushing the poles farther apart.

Answer 15

Anaphase

Question 16

Distinct individual chromosomes
begin to spread out into a tangle of chromatin. The spindle disappears, two nuclear
envelopes reform (one around each set of daughter chromosomes), the chromosomes
uncoil and lengthen, and the nucleoli reappear. Mitosis, the division of one nucleus
into two genetically identical daughter nuclei, is now finished

Answer 16

Telophase

Question 17

completes the division process by dividing the cytoplasm into two
daughter cells, each with a nucleus

Answer 17

Cytokinesis

Question 18

the identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere

Answer 18

Sister Chromatids
