4 DNA & Cell Cycle Review

Front

What is the purpose of cell replication in organisms?

Back

Cell replication is necessary for growth, repair of damaged cells, and replacement of dying cells.

Front

What are the two main stages of the cell cycle?

Back

The two main stages of the cell cycle are interphase and mitosis.

Front

What is the complementary DNA strand for the sequence AGCTAGCTAGCT?

Back

The complementary strand is TCGATCGATCGA.

Front

During which phase of the cell cycle does the cell spend the most time?

Back

The cell spends the most time in interphase.

Front

What enzyme is responsible for unzipping the DNA double helix?

Back

The enzyme that unzips the DNA double helix is helicase.

Front

Define interphase in the context of the cell cycle.

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication and growth.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds and separates the double-stranded DNA into single strands, allowing replication to occur.

Front

What happens during the S phase of interphase?

Back

During the S phase, DNA is replicated, resulting in two copies of each chromosome.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate cells.
