What happens when a cell cannot continue through cellular division?
It goes through apoptosis.
How many pairs of chromosomes do humans have?
23
What is occurring during G1 (Growth 1) of Interphase?
Cell is growing and developing while preforming normal functions.
What phase of mitosis has the chromosomes lining up in the middle of the cell?
Metaphase
What is produced through meiosis?
Gametes
What is apoptosis?
Programmed cellular death.
What are the two types of nuclear division?
Mitosis and Meiosis
What is the division of the cytoplasm called?
Cytokinesis
What is the purpose of mitosis?
Growth and repair of tissues.
Reproduction that results in a clone of the parent, does not need a partner to reproduce.
What is heredity?
The passing of genetic traits from one generation to the next.
Cell is duplicating organelles and chemicals needed for cell division.
What are the stages of mitosis in order?
Prophase, Metaphase, Anaphase, Telophase (PMAT)
Which division of meiosis are homologous chromosomes present?
Cancer
How many individual chromosomes do humans have?
46
Why do cells need to replicate their DNA before cell division?
To ensure each daughter cell gets the right number of chromosomes.
What is the difference between telophase and cytokinesis?
Telophase is just the division of the nucleus and the reforming of the nuclear membrane while cytokinesis is the division of the cytoplasm.
Why is meiosis important?
Increases genetic variation in populations.
What is the protein that holds sister chromatids together?
Centromere
What is it called when sister chromatids or homologous chromosomes fail to separate during anaphase?
