CELS191 Lecture 14: Eukaryotic Cell Division - Mitosis

These flashcards cover key concepts related to eukaryotic cell division and mitosis as discussed in the CELS191 Lecture 14.

What is a karyotype?

An organized visual display of a cell's chromosomes, arranged in homologous pairs.

What are the five phases of mitosis in order?

Prophase, Prometaphase, Metaphase, Anaphase, Telophase and Cytokinesis.

During which phase of mitosis are sister chromatids separated?

Anaphase.

What occurs in the S phase of the cell cycle?

Metabolic activity, growth, and DNA synthesis.

How many chromosomes do diploid human cells contain?

46 chromosomes, or 23 pairs.

What happens during telophase and cytokinesis?

Formation of two daughter nuclei and division of the cytoplasm resulting in two daughter cells.

What is the function of the mitotic spindle?

To separate sister chromatids during mitosis.

What type of DNA do eukaryotic cells have?

Linear double-stranded DNA.

How is cytokinesis different in plant cells compared to animal cells?

In plant cells, cytokinesis involves the formation of a cell plate; in animal cells, a cleavage furrow forms.

What is meant by homologous chromosomes?

A pair of chromosomes with the same genes, one inherited from each parent.
