Cell Division Basics
The process in which a parent cell divides and produces two identical daughter cells, each with the same number of chromosomes as the parent cell
What is Mitosis?
Prep for Mitosis
What is Interphase?
What meiosis cells are for
What is Sexual Reproduction?
Tightly wound DNA around proteins
What are Chromosomes?
Process in which new cells with genetic variability produced
What is Meiosis?
Phase of the cell cycle that DNA replication occurs
What is the S phase (Synthesis phase)?
Spindle fibers start, the nuclear envelope breaks, chromosomes condense
What is Prophase?
Prep for Meiosis
What is Interphase?
What protein is the DNA wrapped around
What are Histones?
Stage of meiosis where the synapsis of homologous chromosomes occur, leading to the exchange of genetic material between non-sister chromatids
What is the Prophase I of Meiosis?
Term for the point at which two chromatids are joined together in a replicated chromosome
What is the centromere?
Chromosomes line up
What is Metaphase?
Results in half the chromosomes in each cell
What is Meiosis?
Contains our genetic makeup
What is DNA?
Term for the exchange of genetic material between homologous chromosomes, contributing to genetic diversity in offspring
What is crossing over?
Term for the structures that organize and separate chromosomes during cell division, forming the mitotic spindle
What are centrioles or spindle fibers?
Chromatids separate/pulled towards opposite ends of the cell by the spindle fibers.
What is Anaphase?
A brief resting period for the 2nd round of cell division in Meiosis
What is Interkinesis?
Name of the region where two sister chromatids are joined together in a chromosome
What is the centromere?
Term that refers to the random assortment of maternal and paternal chromosomes during meiosis, contributing to genetic diversity in offspring
What is independent assortment?
The process in which you get 4 non-identical cells from 1 parent cell
What is Meiosis!
cell wall forms separating them into two separate cells. the nuclear envelope starts to reform and the spindles disassemble.
telekinesis/cytokines
The cells that meiosis makes
What are Gametes?
telomeres
Term for the process where the number of chromosomes is halved, resulting in haploid cells
What is reduction division?
