Process of Mitosis
What are the four phases of mitosis
telophase, metaphase, anaphase, prophase
When does crossing over occur?
Prophase 1
A rigid layer of nonliving material that surrounds the cell.
The cell wall
The period from cell formation to cell division.
Interphase
Two major periods of the cell cycle
Interphase and cell division
What is the final phase of mitosis?
Telophase
When do chromosomes line up in a single file?
Metaphase 2
The outside boundary of a cell that controls which substances can enter of leave
cell membrane
Interphase period of growth after mitosis cell grows in size and increases in volume
G1 phase
What are the stages of interphase
G1, S phase, G2
During which phase of mitosis do spindle fibers first form?
Prophase
When does DNA replication take place?
Interphase
The cell's control center
nucleus
Interphase period during which DNA is replicated and centrosome replicates
S phase
How many chromosomes do humans have?
46
What is condensed genetic material called
chromatids
Cytoplasm divides and 2 daughter cells are formed.
telophase 1
Small object within the nucleus that helps make ribosomes.
nucleolus
The division of the cell's nucleus
mitosis 2
What are chromosomes made up of?
Homologous chromatids
During which phase does the number of chromosomes double?
anaphase
How many cell division are there in meiosis
two cell divisions
The bulk of the cell that contains all the organelles
cytoplasm
The division of the cytoplasm of a cell
cytokinesis
How many chromosomes does a human cell have at the end of meiosis 2
