Unit 7 Mitosis & Meiosis

Question 0

What is chromatin?

Answer 0

Uncoiled DNA found in the nucleus

Question 1

What are the two types of cell division?

Answer 1

Mitosis and meiosis

Question 2

What is chromatid?

Answer 2

One half of a duplicated chromosome

Question 3

What is centromere?

Answer 3

the structure that hold together the chromatids

Question 4

What are the five phases of mitosis?

Answer 4

Prophase, metaphase, anaphase, telephase, cytokinesis

Question 5

What occurs in prophase for mitosis?

Answer 5

Nucleus disappears, centrioles migrate, spindles begin to form, and chromosomes become visible

Question 6

What occurs in metaphase for mitosis?

Answer 6

Chromosomes line up at cell equator

Question 7

What occurs in anaphase for mitosis?

Answer 7

Duplicated chromosomes separate and head to opposite poles of the cell

Question 8

What occurs in telophase for mitosis?

Answer 8

Chromosomes reach opposite poles, nucleus reforms

Question 9

What occurs in cytokinesis for mitosis?

Answer 9

Division of cytoplasm & organelles into the two daughter cells

Answer 11

Gametes (sex cells)

Question 12

Answer 12

The union of 2 sex cells (egg & sperm)

Question 13

What are diploids? Haploids?

Answer 13

having two sets of chromosomes, having one set of chromosomes

Question 14

What does meiosis produce?

Answer 14

Haploid gametes (one set of chromosomes)

Question 15

what happens in meiosis 1 that is different from mitosis?

Answer 15

genetic material from homologous chromosomes is exchanged / recombined

Question 16

What are the results of meiosis?

Answer 16

Four haploid daughter cells, only 1 can become an egg for a female. All become sperm for men
