Cellular Reproduction
This is the loose, threadlike form of DNA found when a cell is not dividing.
Chromatin.
DNA replication occurs during this phase
S phase
What is cancer?
A disease where cells divide uncontrollably due to mutations affecting cell cycle regulation
To produce two genetically identical daughter cells for growth, repair, and replacement
This type of reproduction produces genetically identical offspring from one parent
Asexual Reproduction (binary fission)
DNA wraps around these proteins to form nucleosomes.
Histones
Most of the cell cycle is spent in this stage.
Interphase
What are proteins that regulate whether a cell divides called?
Cell cycle regulators
During which phase of mitosis do chromosomes line up in the middle of the cell?
Metaphase
During this process, the cell copies all of its DNA before dividing.
DNA replication
Two identical copies of a chromosome joined together are called these.
Sister chromatids
Name the four phases of the cell cycle in order.
G1 -> S -> G2 -> M
What type of gene normally prevents uncontrolled cell division.
Tumor suppressor gene
During which phase do sister chromatids separate and move to opposite sides of the cell?
Anaphase
According to cell theory, all cells come from _____.
Preexisting cells
This structure holds sister chromatids together.
Centromere.
Cells that permanently stop dividing enter this phase.
G0
What is a tumor?
A mass of abnormal cells caused by uncontrolled cell division.
What happens during telophase?
Two new nuclei form around the separated chromosomes.
What are the two major processes involved in cellular reproduction?
Growth and Cell Division
46 chromosomes (23 pairs)
During this phase, the cell prepares for mitosis by making proteins and microtubules
What is metastsis?
The spread of cancer cells from one part of the body to another.
Put the stages of mitosis in the correct order
Prophase -> Metaphase -> Anaphase -> Telophase (PMAT)
