Front

What are the three parts of a signal transduction pathway?

Back

Reception, Transduction, Response

Front

Which checkpoint is responsible for ensuring nondisjunction does not take place?

Back

M checkpoint

Front

What is the impact of a mutation in any domain of the protein components of the transduction signaling pathway?

Back

Alters response of the cell

Front

Which of the following is NOT a role of mitosis?

Back

Production of gametes

Front

What does mitosis result in?

Back

2 identical diploid cells

Front

Define signal transduction.

Back

The process by which a cell responds to external signals through a series of molecular events.

Front

What is the role of the G1 checkpoint?

Back

To assess cell size, DNA integrity, and nutrient availability before DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication, resulting in two sister chromatids for each chromosome.

Front

What is the function of the G2 checkpoint?

Back

To ensure that DNA has been replicated correctly and to prepare for mitosis.

Front

What is the difference between haploid and diploid cells?

Back

Diploid cells have two sets of chromosomes, while haploid cells have one set.
