Microbiology Mastering Chapter 12 & 13

The sister chromatids separate and begin moving toward opposite poles of the cell during which phase of mitosis?

Anaphase

The chromosomes line up in the center of the cell during which phase of mitosis?

Metaphase

The centrosomes move away from each other and the nuclear envelope breaks up during which phase of mitosis?

Prophase

The chromosomes arrive at the poles and nuclear envelopes form during which phase of mitosis?

Telophase

What must happen before a cell can begin mitosis?

The chromosomes must be duplicated.

At the end of the mitotic (M) phase, the cytoplasm divides in a process called _________________.

cytokinesis

Meiosis starts with a single diploid cell and produces

four haploid cells.

During prophase I of meiosis,

homologous chromosomes stick together in pairs.

A cell preparing to undergo meiosis duplicates its chromosomes during

interphase.

The correct order of events during meiosis is

prophase I, metaphase I, anaphase I, telophase I, cytokinesis, meiosis II.

During meiosis, segments of non-sister chromatids can trade places. This recombination of maternal and paternal genetic material is a key feature of meiosis. During what phase of meiosis does recombination occur?

prophase I.
