Cell Cycle
During this stage of Interphase, DNA is replicated
What is S phase
You inherit these, one from each parent!
What are Homologous chromosomes
The number & type of cells created at the end of meiosis
When chromosome segments are exchanged/swapped between homologous chromosomes
What is Crossing over
Permanent change to the DNA sequence
What is Mutation
The stage where the cell grows & performs its job
What is G1 phase
The type of cells that are considered to be haploid
What are Gametes
Number of cells at the end of Telophase 1 of meiosis
What are 2 cells
The failure of homologous chromosomes to separate properly
What is Nondisjunction
These are the same length, have the same centromere positioning, and carry genes in the same places
What are Homologous chromosomes
Formed after cytokinesis in mitosis
What are two identical cells
Each version of a gene is called
What is Allele
The HAPLOID number of chromosomes in humans
What is 23
Name at least one way that genetic diversity occurs with meiosis
Could say...
What is crossing over, or nondisjunction, or indepedent assortment, or random fertilization, or mutations
A part of a cell's life including G1, S & G2
What is Interphase
Caused when the cell cycle is unregulated & where cells grow out of control
The cell division that reduces the # of chromosomes by half, through separation of the homologous chromosomes
What is Meiosis
The total number of chromosomes an organism has
What is Diploid
During Metaphase 1, homologous chromosomes are randomly lined up in the middle of the cell, adding to genetic variation
What is Independent assortment
Type of cell division that forms somatic cells
What is Mitosis
The correct order of steps in Mitosis
What is: Prophase, metaphase, anaphase, telophase
When a cell stops where its at in the cycle and is instructed to die by a protein
What is Apoptosis
The phase in which Crossing Over occurs
What is Prophase 1
Causes daughter cells to have too many or too few chromosomes in meiosis
What is Nondisjunction
What are Checkpoints
