Flashcards in Cell Repro Quiz Deck (16):
Why do cells undergo mitosis and meiosis?
To creat identical daughter cells
The process of making egg and sperm cells
Distributes DNA to each new cell; identical daughter cell
Normal cellular activity occurs, chromosomes are copied prior to prophase. DNA is in chromatin… Looks like spaghetti.
Nuclear envelope begins to dissolve, leaving the double chromosomes bare. Each separate chromosome is now called a chromatid. These are attached to each other at the centromere.
Chromosomes move to the middle
Chromosomes are split by spindles
New cell wall (w/ plants)
New nuclear envelope
Mitosis: the number of chromosomes in the beginning cells and ending cells
Meiosis: the number of chromosomes in the beginning cells and ending cells
Each chromosome has....
Mom and dad chromosomes get tangled together, and trade equal sections of DNA
No doubling the DNA but other than that the same is prophase 1
Mitosis number of divisions
Meiosis number of divisions
