(29 cards)
What are the 2 types of reproduction
Asexual and sexual
Describe asexual
There is 1 parent
Identical to parent
Describe sexual
2 parent
Genetic info mixed with parents
Why cells grow all at once
The outside is unable to keep up with the inside
How many chromosomes does a human have
46
2 pairs of 23
Describe chromatin
DNA and proteins that makeup chromosomes
Pre division
Describe chromosomes
During division
Chromatid coils up to make chromosomes
Describe sister chromatid
Each chromosome has 2 sister chromatids
What is centromere
Holds chromatids together
What are the 2 types of cells
Sex cells and somatic cells
Describe sex cells
Has an ovum and sperm
For reproduction
Describe somatic cell
Every other type of cell besides from sex cells
What are all the phases in the cell cycle
G1 phase
S phase
G2 phase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
What are the 2 stages in the cell cycle
Interphase and cell division
What g1 phase
Cell growth
What’s s phase
Synthesis data
What’s G2 phase
Cell growth
Prep mitosis
What is prophase
Chromatin coil up into chromosome
Nucleus disappears
Poles form
Spindle fibres form
What’s metaphase
Chromosomes line along the middle of cell
What’s anaphase
Spindle fibers shorten and contract
Centromes separate
Sister chromatids move to opposite poles
What’s telophase
Spindle fibers disappear
Nuclear membrane form around chromosome
Chromosomes uncoil to chromatin
What does mitosis include
Prophase
Metaphase
Anaphase
Telophase
What is cytokinesis
Division of cytoplasm and spilts in 2
What’s the difference between cytokinesis and mitosis
Mitosis- division of nucleus
Cytokinesis- division cytoplasm
