Mitosis Phases
Chromosomes are condensed, spindle fibers form, and the nucleolus is gone.
Prophase
The powerhouse of the cell
Mitochondria
AKA down syndrome. Most common type of trisomy.
Trisomy 21
What is a checkpoint?
Place where the cell decides if it should move forward or not with division.
Tightly packed DNA and protein structure.
Chromosome
Chromosomes start unwinding, spindle fibers disassemble, and the nuclear envelope starts to form.
Telophase
Synthesizes and stores lipids
Smooth ER
How many trisomy's are viable past birth?
3
Makes sure DNA replication is done.
G2 Checkpoint
Identical DNA strands. They stay attatched until mitosis.
Sister Chromatids
Cytoplasm divides, creating 2 cells.
Cytokinesis
Packages proteins and lipids to transport in and out of the cell.
Golgi Apparatus
AKA Patau Syndrome. Causes defects in the circulatory system, eyes, and brain.
Trisomy 13
Cell dies to stop the spread of cancer.
Apoptosis
2 chromosomes with identical features.
Homologus Chromosome.
Anaphase
Place where photosynthesis occurs.
Chloroplasts
AKA Edward's Syndrome. Causes babies to have a small heart
Trisomy 18
Makes sure chromosomes are perfectly attached to mitotic spindle.
Mitotic Phase Checkpoint
Move chromosomes through the cell during mitosis.
Spindle Fibers
Chromosomes line up in the middle of the cell.
Metaphase
Help transport proteins to the Golgi Apparatus.
Ribosomes
70% of cases go undiagnosed. Only in males.
Klinefelter’s syndrome (XXY)
Makes sure a cell has enough space and organelles to be able to replicate.
G1
Area on the centromere where the spindle fibers attach,
Kinetochores
