Unit 07 - Cell Division & Reproduction

Before cell division takes place, DNA has to make an exact copy of itself. This is called

• duplication

• fertilization

• hybridization

• replication

How many chromosomes are found in a human adult egg cell?

• 23

• 46

• 23 pairs

• 46 pairs

Meiosis results in

• two unique daughter cells

• four identical daughter cells

• two identical daughter cells

• four unique daughter cells

When meiosis is complete, how does DNA in the daughter cells compare to the DNA from the original parent cell?

• half as much and genetically the same

• twice as much and genetically the same

• half as much and genetically different

• twice as much and genetically different

Mitosis or Meiosis: Single parent (diploid) cell produces four haploid (n) daughter cells

• mitosis

• meiosis

After fertilization, the zygote contains 28 chromosomes. What is the haploid number?

• 28

• 14

• 56

• 46

The stages of mitosis are sometimes referred to as

• PMAT

• PMAP

• MPTA

• ATPM

When a cell goes through mitosis, the daughter cells

• are genetically unique from the mother cell

• are genetically identical to the mother cell

• are used in sexual reproduction

• have half the number of chromosomes as the mother cell

What is the purpose of Mitosis?

• Growth of an organism and Repair of damaged tissue

• To help the body get rid of extra cells

• To increase the amount of classwork you have to do

• To get rid of the nucleus

How many chromosomes to do most human cells have?

• 2

• 46

• 92

• Identical to your age
