Unit 4 Test

Front

What is the process by which humans produce skin cells?

Back

Mitosis.

Front

What is the process by which humans produce gametes?

Back

Meiosis.

Front

How much DNA do skin cells produced by mitosis have compared to gametes produced by meiosis?

Back

Twice as much DNA.

Front

What distinguishes eukaryotic cells from prokaryotic cells in terms of DNA?

Back

Eukaryotic cells typically have more DNA molecules and larger genomes.

Front

At which phase of mitosis do sister chromatids become daughter chromosomes?

Back

Anaphase.

Front

What type of receptors are involved in many human diseases, including cholera and whooping cough?

Back

G protein coupled receptors.

Front

In which stage of the cell cycle would a nucleus contain 6 picograms of DNA?

Back

G2 phase.

Front

What is the main difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is the role of G protein coupled receptors in human physiology?

Back

They are involved in signal transduction and can affect various cellular responses.

Front

What is the significance of the G1 phase in the cell cycle?

Back

It is the phase where the cell grows and prepares for DNA replication.
