Define Mitosis
answer
Mitosis is a type of cell division in two daughter cells; each having the same numbers and kind of chromosomes as the parent nucleus
question
Summarize the stages of interphase
answer
The stages of interphase 1: G1 stage - Has cell groups and normal functions 2: S stage - DNA is replicated 3: G2 stage - cells prepare for mitosis
question
Clarify the difference between chromatin and chromosomes
answer
Chromatin condenses to form chromosomes during the cell's division.
question
Distinguish between mitosis and cytokinesis
answer
Mitosis involves nuclear division but it still contains a single cell. Cytokinesis is the division of the cell after mitosis is completed
question
List two alternative futures for cells when they reach their size limitations
answer
1: die 2: divide
question
Draw the cell cycle in the space below. Include the following labels: G1' S' G2' Mitosis and Cytokinesis
answer
G1 --> S --> G2 ->> M --> C --> (It's a cycle so it needs to be in a circle)
question
Stage in which the cell divides into two daughter cells with identical nuclei
answer
B. cytokinesis
question
substage of interphase immediately after a cell divides
answer
C. G1
question
substage of interphase in which the cell copies its DNA in preparation for cell division
answer
A. S phase
question
stage in which the cells nuclear material divides and separates
answer
F. misosis
question
main stage in which the cell grows. carries out normal functions, and duplicates DNA
answer
E. interphase
question
substage in which the cell prepares for nuclear division and a protein that makes microtubes for cell division is synthesized
answer
D. G2
