DNA
Holds our genetic information
What is DNA?
What is the process by which a eukaryotic cell divides into two identical daughter cells?
What is mitosis?
Cell spends 90% of its time here (Normal cell life)
What is interphase
What is the preferred ratio of surface area to volume in a cell?
Large surface area to volume ratio
Stages of interphase in order
3 stages: G1, S, G2
During which phase of the cell cycle does DNA replication occur?
What is the S phase of interphase (Synthesis phase)?
How many phases are in mitosis
What is 4
the chromosomes first start to condense in this phase
What is prophase?
Area where spindle fibers attach to chromosome
What is centromere
What is prokaryote cell division called?
Binary Fission
DNA that condenses during cell division
What is Chromatin
How many cells form after mitosis?
What is two cells?
In this mitosis stage, the chromosomes start to move to the poles of the cell?
What is anaphase?
An apparatus of strings that controls chromosome movement during mitosis

The two halves of duplicated chromosomes are called?
Chromatids
What are the 4 stages of mitosis? (in order)
What is prophase, metaphase, anaphase, and telophases?
Football-shaped structure consisting of thin fibers that
migrate to poles during prophase
What is the term for the uncontrolled and rapid division of cells, often associated with the formation of tumors?
What is cancer?
Humans have how many chromosomes in a cell?
What is 46 or 23 pairs
What is the significance of cytokinesis in cell division?
What is the division of the cytoplasm and other organelles, resulting in two separate daughter cells?
During this stage, the nucleus splits up.
What is telophase?
List two reasons cells cannot survive at a large size
The DNA would be overloaded providing instructions for proteins. The cell would also not be able to efficiently exchange materials.
A cell that is totipotent
