Unit 3 Test Review

Uncontrolled or unregulated cell division is

• cancer

• mitosis

• cytokinesis

• interphase

What is the correct order for the phases of mitosis?

• prophase, anaphase, telophase, metaphase

• prophase, metaphase, anaphase, and telophase

• telophase, prophase, anaphase, and metaphase

• metaphase, telophase, prophase, and anaphase

What is the complimentary strand of this sequence of DNA

• GTCGGTAG

• CTACCGAC

• GTCCCTAG

• CAGCCATC

A DNA molecule untwists, then the two strands of DNA seperate. After this, molecular bases pair up. At the end of this process two identical DNA molecules are produced. What process is this?

• Fertilization

• Mutation

• DNA Replication

• Recombination

Which is the nucleotide?

• F

• A

• B

• E

In DNA, which of the following determines the traits of an organism?

• the number of adenines

• the number of nucleotides

• the sequence of nucleotides

• the number of nitrogen bases

In this phase of mitosis, the chromosomes condense and the nuclear envelope begins to break down.

• telophase

• anaphase

• prophase

• metaphase

DNA replication ensures

• the parent cell has energy

• both new daughter cells have identical copies of the parent cell DNA

• both new daughter cells have different DNA from each other and the parent cell

• only one new daughter cell does not have an identical copy of the parent cell DNA

Which are the hydrogen bonds?

• E

• F

• G

• A

In mitosis

• The cell grows

• The cell does nothing

• The cell divides

• The cell dies
