Protein Synthesis, Meiosis, and Mutations Test Review

Match the following for mitosis and meiosis.

• Anaphase 2 of Meiosis

• PMAT happens once or twice

• Mitosis

• makes 2 identical cells

• Mitosis & Meiosis

• Sister Chromatids (already crossed over) pull apart

• Meiosis

• makes 4 genetically different cells

• Anaphase 1 of Meiosis

• Homologous Chromosomes pulled apart & Independent assortment

2 diploid (2n) daughter cells form in what phase of Meiosis?

• Telophase 2

• Telophase/Cytokinesis 1

• Anaphase 2

• Cytokinesis 2

Which of the following are CORRECT observations about MITOSIS and MEIOSIS? (Check all that apply.)

• Mitosis produces cells that identical to the parent cell.

• Meiosis produces cells that have half the number of chromosomes as the parent cell.

• All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.

• In both types of cell division, the chromosomes are only duplicated once.

• Only in Mitosis, do you see chromosomes pair up to form a tetrad.

Crossing over usually occurs between:

• Sister Chromatids

• Homologous Chromosomes

• Alleles

• Non-Homologous Chromosomes

If an egg cell of an organism contains 12 chromosomes, how many chromosomes should be present in a heart cell of the same organism?

• 12

• 24

• 6

• 48

Answer explanation

Sex cells contain half the number of chromosomes as body cells.

How many chromosomes does a sex cell have compared to a body cell?

• twice as many

• the same amount

• the same, but replicated

• half as many

The matching pair of chromosomes you inherit from your genetic parents are called

• sister chromatids

• autosomes

• homologous chromosomes

• sex chromosomes

What is the purpose of meiosis?

• growth

• repair

• reproduction

• to create identical cells

What is the purpose of mitosis?

• growth and repair

• reproduction

• genetic diversity

• to create unique cells

A diploid cell...

• has 1/2 the amount of chromosomes

• has the normal amount of chromosomes (46)

• is represented by (n) in meiosis
