QUESTION
8-1 CHROMOSOMES
1. Uncoiled DNA that is wrapped around histone
proteins
ANSWER
Chromatin
2. Tightly packed chromatin that you can see
during cell division
3. Two identical copies of the same chromosome
joined together
4. Where #3 are joined together
5. Chromosomes not involved with your gender
6. How many #5’s do you have in your body
cells?
7. Chromosomes that determine your gender
8. How many #7’s do you have in your body
cells?
9. A diploid (2n) cell has how many sets of
homologous chromosomes?
Chromosomes
10. Give an example of a diploid cell
Skin cell, muscle cell
11. A haploid (n) cell has how many sets of
chromosomes?
12. Give an example of a haploid cell
13. Chromosomes that have the same kinds of
genes on them
14. A picture of your chromosomes
15. If you are a male, you would see these as
your sex chromosome pair (23rd pair)
16. If you are a female, you would see these as
your sex chromosome pair (23rd Pair)
8-2 CELL DIVISION
17. Two main stages of the Cell Cycle
One set (one of each homologue)
18. Three stages of Interphase & what happens
in each:
Sister chromatids
Centromere
Autosomes
44 (22 pairs)
Sex chromosomes
2 (1 pair)
Two sets of homologous chromosomes
Egg or sperm (gametes)
Homologous
Karyotype
XY
XX
1) Interphase
2) Cell Division
1) G1 – cell growth
2) S – DNA (chromosome) replication
3) G2 – prep for mitosis
19. Two Stages of Cell Division
20. Four Phases of Mitosis
1) Mitosis – nuclear division
2) Cytokinesis – cytoplasmic division
1) Prophase
2) Metaphase
3) Anaphase
4) Telophase
21. Phase of mitosis where chromosomes lined
up in middle of the cell
22. Phase of mitosis where centromeres divide,
pulling apart the sister chromatids
23. Phase of mitosis where you can first see
sister chromatids & nuclear membrane
disappears
24. Phase of mitosis where chromosomes uncoil
and nuclear membrane reappears
25. What are two reasons multicellular
organisms (like you) need the process of mitosis?
26. This process takes place after the nucleus
divides
8-3 MEIOSIS
27. What is the purpose for the process of
meiosis?
28. How many rounds of division in meiosis?
29. Sex cells (egg & sperm)
30. Creation (Birth) of sperm cells
31. Creation (Birth) of egg cells
32. How many egg cells are actually created
during #31?
32. When chromosomes exchange corresponding
segments of DNA
33. What phase does #32 happen in?
34. During prophase I, a pair of homologous
chromosomes finds one another (each existing as
a pair of chromatids – so 4 chromatids total)
creating this
Metaphase
35. What gets separated during Anaphase I?
36. What gets separated during Anaphase II?
37. If chromosomes do not get separated
properly during meiosis, this can happen
Homologous pairs of chromosomes
Sister chromatids
Gametes with an incorrect number of
chromosomes – could lead to a person with
an abnormal number of chromosomes.
Anaphase
Prophase
Telophase
Growth and repair
Cytokinesis
Creation of gametes – necessary for sexual
reproduction
2 (Meiosis I and Meiosis II)
Gametes
Spermatogenesis
Oogenesis
Only 1 – the other three cells are polar
bodies
Crossing over
Prophase I
A tetrad
COMPLETE THE FOLLOWING TABLE THAT COMPARES MITOSIS & MEIOSIS –
put an “X” in the appropriate column for each statement
MITOSIS
X
Creates genetically identical cells
Creates genetically different cells
Creates 4 daughter cells
Creates 2 daughter cells
Creates cells with the same number of
chromosomes as the parent cell
Creates cells with half the number of
chromosomes as parent cell
Begins with a diploid cell
Separates homologous chromosomes
Separates sister chromatids
Creates gametes (sex cells like egg and sperm)
Creates body cells (like skin or muscle cells)
