Cell Cycle Warmup

What occurs during the S phase of the cell cycle?

• DNA replication
• Chromosome segregation
• Protein synthesis
• Cell division

What occurs during the G1 phase of the cell cycle?

• Cell growth and normal function
• DNA synthesis and replication errors
• Cell death and apoptosis
• Cell division and replication

What occurs during the G2 phase of the cell cycle?

• Cell differentiation and specialization
• Synthesis of new DNA
• Preparation for cell division and organelle replication
• Cell growth and increase in size

Scientists have concluded that repeated exposure to high doses of X-rays can lead to cancer in individuals. How does the X-ray exposure result in cancer?

• X-ray exposure can result in cancer by increasing the production of healthy cells
• X-ray exposure can result in cancer by reducing the risk of mutations in DNA
• X-ray exposure can result in cancer by promoting controlled cell growth
• X-ray exposure can result in cancer by damaging the DNA in cells, leading to mutations and uncontrolled cell growth.

An experiment is successful in disrupting cell division in human pancreatic cells. What process is significantly disrupted and stopped?

• cellular respiration

• photosynthesis

• cell growth and normal cell functioning
