Unit 4 - 6 AP Biology Insta-Review

Front

What process caused the daughter cells to be haploid?

Back

Anaphase I/Telophase I is the stage in meiosis where homologous chromosomes are separated, resulting in haploid daughter cells.

Front

Do all somatic (body) cells have the same genetic information?

Back

True. All somatic cells in an organism contain the same DNA, although they may express different genes.

Front

How is calcium released from the smooth ER?

Back

Calcium is released from the smooth endoplasmic reticulum through gated ion channels.

Front

What is the effect of adding a methyl group to DNA?

Back

Adding a methyl group increases DNA condensation, which decreases transcription.

Front

What is an autocrine signal?

Back

An autocrine signal is a type of signaling where a cell secretes a signal that binds to receptors on its own surface.

Front

What is the role of the smooth endoplasmic reticulum?

Back

The smooth endoplasmic reticulum is involved in lipid synthesis, detoxification, and calcium storage.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells contain one set of chromosomes (n), while diploid cells contain two sets (2n).

Front

What is crossing over in meiosis?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis.

Front

What is independent assortment?

Back

Independent assortment is the random distribution of maternal and paternal chromosomes into gametes during meiosis.

Front

What is the function of gated ion channels?

Back

Gated ion channels regulate the flow of ions across the cell membrane in response to specific signals.
