Cell Cycle and DNA Review

Front

What are the three components of a nucleotide?

Back

Sugar, phosphate, nitrogen base.

Front

What happens to the number of chromosomes during the S phase of the cell cycle?

Back

The number of chromosomes doubles; for fruit flies with 8 chromosomes, it becomes 16.

Front

What phase of Mitosis is characterized by the separation of sister chromatids?

Back

Anaphase.

Front

What part of the cell cycle includes A, B, and C phases?

Back

Interphase.

Front

In double-stranded DNA, which nucleotide is always equal to the amount of Adenine?

Back

Thymine.

Front

What is the function of DNA?

Back

To store and transmit genetic information.

Front

What are the main stages of the cell cycle?

Back

Interphase, Mitosis, and Cytokinesis.

Front

What occurs during the G1 phase of the cell cycle?

Back

Cell growth and preparation for DNA replication.

Front

What is the role of the S phase in the cell cycle?

Back

DNA replication occurs, resulting in duplicated chromosomes.

Front

What is the difference between Mitosis and Meiosis?

Back

Mitosis results in two identical daughter cells; Meiosis results in four genetically diverse gametes.
