Biology (Day 22; Meiosis)

Question 1

Gamete

Answer 1

A sex cell (in males, sperm; in females, egg)

Question 2

Meiosis

Answer 2

A two-step process of cell division that is used to make gametes (sex cells)

Question 3

Crossing over

Answer 3

Process in which homologous chromosomes trade parts

Question 4

Interphase

Answer 4

A phase of the cell cycle where the cell grows and makes a copy of its DNA

Question 5

Sister chromatids

Answer 5

Two halves of a duplicated chromosome

Question 6

What is the purpose of meiosis?

Answer 6

to produce gametes

Question 7

How many daughter cells are produced in meiosis?

Answer 7

4 haploid daughter cells

Question 8

What is the goal of Meiosis 1?

Answer 8

separate homologous pairs

Question 9

Ignoring the results, what is the primary difference between mitosis and meiosis 1?

Answer 9

During anaphase 1 of mitosis, the microtubules pull sister chromatids apart to opposite sides of the cell, whereas in meiosis 1, the microtubules pull a set of sister chromatids to opposite sides of the cell

Question 10

What is the goal of Meiosis 2?

Answer 10

separate sister chromatids

Question 11

Ignoring the results, is there any difference between Mitosis and Meiosis 2?

Answer 11

not necessarily; both are essentially the same process with the same goal

Question 12

When does crossing over occur in meiosis?

Answer 12

prophase 1

Question 13

What is the difference between meiosis and sexual reproduction?

Answer 13

meiosis is essential to sexual reproduction, for it forms gametes; however, sexual reproduction includes fertilization, which is not part of the mitotic process
