Cell Cycle and Mitosis Practice

What happens during the G1 phase of Interphase?

• DNA replication

• Cell growth and normal functions

• Preparation for mitosis

• Chromosome condensation

During the S phase of Interphase, the cell primarily focuses on:

• Cell division

• DNA replication

• Protein synthesis

• Organelle duplication

What is the main activity of the G2 phase of Interphase?

• Cell growth and preparation for mitosis

• DNA replication

• Cell division

• Chromosome condensation

During prophase of Mitosis, which of the following occurs?

• Chromosomes align at the cell's equator

• Sister chromatids separate

• Nuclear envelope breaks down

• Chromosomes decondense

What is the key feature of metaphase in Mitosis?

• Chromosomes condense

• Chromosomes align at the cell's equator

• Nuclear envelope re-forms

• Sister chromatids separate

During anaphase of Mitosis, what major event occurs?

• Chromosomes decondense

• Nuclear envelope breaks down

• Sister chromatids separate and move to opposite poles

• Chromosomes align at the cell's equator

Which phase of Interphase is characterized by intense metabolic activity and vigorous growth?

• G1 phase

• S phase

• G2 phase

• M phase

In which phase of Interphase does the cell double its organelles and accumulates the materials needed for DNA synthesis?

• G1 phase

• S phase

• G2 phase

• M phase

What marks the completion of the S phase in Interphase?

• Cell has doubled in size

• Chromosomes are fully condensed

• DNA content of the cell has been duplicated

• Cell divides into two daughter cells

Which of the following best describes the G2 phase of Interphase?
