Cell Cycle & Mitosis

Front

What is chromatin?

Back

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells, which condenses to form chromosomes during cell division.

Front

What processes lead to the formation of new cells?

Back

Cells come from preexisting cells through the processes of mitosis and cytokinesis.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death, where cells undergo an orderly death to eliminate damaged or unnecessary cells.

Front

What is the end result of mitosis?

Back

The end result of mitosis is the formation of 2 identical body cells, each with the same number of chromosomes as the original cell.

Front

Why is DNA replication important before cell division?

Back

DNA replication is crucial before cell division to ensure that genetic information is accurately transferred to daughter cells.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during cell division.

Front

What happens during interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, replicates its DNA, and prepares for mitosis.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome, connected by a centromere, formed during DNA replication.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.

Front

What is a stem cell?

Back

A stem cell is an undifferentiated cell that has the potential to develop into various cell types in the body.
