Mitosis
The cells this type of cell division occurs in.
What are somatic cells?
The cells this type of cell division occurs in.
Gametes
Humans have 23 pairs.
What are chromosomes?
The two phases of the cell cycle.
What is interphase and cell division?
Uncontrolled cell growth.
What is cancer?
The four phases of mitosis.
What is prophase, metaphase, anaphase, and telophase?
Chromosomes form and homologous pairs form tetrads in this phase.
What is prophase I?
Cells with 2 sets of chromosomes.
What are diploid cells?
The specific stage in the cycle in which DNA replication occurs.
What is synthesis phase?
The proteins that DNA wraps around.
What are histones?
DNA coils into chromosomes, nucleolus and nuclear membrane break down, centrosomes and spindle fibers appear.
What is prophase?
Each homologous chromosome is pulled to opposite sides of the cell.
What is anaphase I?
Different forms of a gene.
What is an allele?
The 3 phases of interphase.
What is G1 (growth), S (synthesis), and G2 (growth 2)?
A genetic disorder in which a person has three copies of a chromosome instead of two.
What is trisomy?
Chromosomes are moved to the center of the cell and held there.
What is metaphase?
Follows meiosis I.
What is meiosis II?
Each identical copy of DNA on a chromosome.
What is a sister chromatid?
A rest phase in which no DNA replication occurs.
What is G-0 phase?
Kinetochore fibers and polar fibers.
What are spindle fibers?
TTAGGG.
What is the nucleotide sequence for a telomere?
Genetic info is transferred between homologous pairs of chromosomes.
What is crossing over?
Connects sister chromatids.
What is a centromere?
Proteins regulate the cell's progression through the cell cycle, and signals direct for the next phase of the cycle or for the cycle to halt.
What are checkpoints?
The area of the cell membrane that pinches in and eventually separates the dividing cell into 2 cells.
What is cleavage furrow?
