Exam 4 Flashcards
What does Mitosis produce?
Identical daughter cells, identical to each other, and identical to parental cell
List the 5 stages of Mitosis
Prophase Metaphase Anaphase Telophase Cytokinesis
What happens inside of Prophase?
Nuclear envelope breaks down
Spindle apparatus forms
Chromosomes are condensed and attached to the spindle
How many chromosomes and how many molecules are in Prophase?
4 replicated chromosomes
8 molecules of DNA
What happens inside of Metaphase?
Chromosomes move to the center of the cell and line up on Metaphase plates
How many chromosomes and how many molecules are in Metaphase?
4 replicated chromosomes
8 molecules of DNA
What happens inside of Anaphase?
Replicated chromosomes pull apart
How many chromosomes and how many molecules are in Anaphase?
8 unreplicated chromosomes
8 molecules of DNA
What happens inside of Telophase?
Chromosomes move to the poles of spindle, bunched in two groups
How many chromosomes and how many molecules are in Telophase?
8 unreplicated chromosomes
8 molecules of DNA
What happens in Cytokinesis?
Two cells are formed
What is produced out of Cytokinesis?
Two daughter cells each having 4 unreplicated chromosomes and 4 molecules of DNA
What does Meiosis produce?
Produces non-identical daughter cells, not identical to each other, and not identical to parental cells
In Meiosis, how are the daughter cells compared to the parental cells?
There is half the number of chromosomes
What happens in Prophase I that is different than Mitosis?
homologous chromosomes come together in synapsis and tetrad formation occurs allowing crossing over to be possible
