Cell Cycle & DNA

Front

What must occur prior to complementary nucleotides being added to the new DNA strands during DNA replication?

Back

The DNA molecule must be 'unzipped'.

Front

What phase of the cell cycle involves the reformation of the nuclear membrane around each new cell after genetic material has been separated?

Back

Telophase.

Front

In which phase of mitosis do the chromosomes separate in half?

Back

Anaphase.

Front

What is the final outcome of the cell cycle, where identical daughter cells are created?

Back

Identical daughter cells are created.

Front

In which phase of the cell cycle is the DNA molecule replicated (copied or doubled)?

Back

S phase.

Front

What is the primary purpose of the S phase in the cell cycle?

Back

To replicate the DNA.

Front

What are the main stages of the cell cycle?

Back

Interphase (G1, S, G2) and M phase (mitosis and cytokinesis).

Front

What happens during prophase in mitosis?

Back

Chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the role of spindle fibers during mitosis?

Back

To help separate the chromosomes during anaphase.

Front

What is cytokinesis and when does it occur?

Back

Cytokinesis is the division of the cytoplasm, occurring after mitosis.
