Cell cycle and cell division

Front

What is the cell cycle?

Back

A series of events that take place to duplicate DNA and produce daughter cells.

Front

How many chromosomes are present in human body cells?

Back

46

Front

What happens during Anaphase?

Back

The centromere divides and sister chromatids are drawn apart towards different poles of the cell.

Front

What is crossing over in genetics?

Back

The exchange of specific genes found at the same locus between homologous chromosomes.

Front

What occurs during Prophase?

Back

Chromosomes get duplicated, the nucleus and nucleolus disappear, and spindle fibers appear.

Front

What is the role of centromeres during cell division?

Back

Centromeres attach sister chromatids to spindle fibers during cell division.

Front

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

Back

It is the phase where DNA replication occurs, resulting in duplicated chromosomes.

Front

What are sister chromatids?

Back

Identical copies of a chromosome, connected by a centromere, formed during DNA replication.

Front

What is the function of spindle fibers?

Back

Spindle fibers help separate sister chromatids during cell division.

Front

What is cytokinesis?

Back

The process that follows mitosis, where the cytoplasm divides to form two separate daughter cells.
