Chapter 10

Question 1

SEQ DNA packaging

Answer 1

DNA → Nucleosomes (DNA + histones) → Chromatin → Chromosome.

Question 2

CC chromosome structure and number

Answer 2

Locus: specific location on chromosomes
Haploid (n): one set of chromosomes, Gametes are haploid
Diploid (2): 2 sets of chromosomes, Homologous pair, Somatic Cells (46 chromosomes) are diploid

Both Haploid and Diploid goes through mitosis

Question 3

SEQ, HD, CC stages of the cell cycle (2)

Answer 3

Interphase
M-Phase

Question 4

Interphase (3 long)

Answer 4

G1
S
G2

Question 5

G1

Answer 5

GDF
No DNA synthesis

Question 6

S

Answer 6

Chromosome Replication (DNA + Protein Synthesis)

After Replication
each chromosome = two sister chromatids (Same pair)

SC are attached by centromeres
Kinetochores: attach at the centromere (microtubules)

Question 7

G2

Answer 7

2x DNA
Centrosome: produces mitotic spindles and 2 centrosome

Question 8

M-Phase (2 short)

Answer 8

Mitosis
Cytokinesis

Question 9

Mitosis (4 PMAT)

Answer 9

Prophase
Metaphase
Anaphase
Telophase

Question 10

Prophase

Answer 10

Mitotic Spindle formation
Centrosomes move to opposite sides

Question 11

Metaphase

Answer 11

Chromosomes move to the metaphase plate (center)
Mitotic spindle attaches to kinetochores

Question 12

Anaphase

Answer 12

Each SC separated by enzyme

Question 13

Telaphase

Answer 13

chromosome decondensed to chromatin
nuc env reforms = 2 identical daughter nuclei

Question 14

Cytokinesis

Answer 14

divides the cell and results 2 daughter cells
