Mitosis Flashcards
(24 cards)
Mitosis
Division of the cell membrane
Cytokenesis
The part after telophase where the cell has completely split into two identical parts
Chromosome
Holds DNA and other genetic information in genes
DNA
The carrier of genetic information
Gene
Controls the basic traits passed onto a offspring. Uses DNA and RNA
Bases or Nucleotides
Makes up DNA and RNA, part of a phosphate group
Chromatin
The chromatin makes up chromosomes that contain DNA and RNA
Chromatid
Part of a chromosome that has a single centromere
Centromere
The spindles attach here during mitosis
Cell Cycle
The cell splits and divides into two cells using six different stages.
Interphase
The stage in the cell in which the nucleus is clearly outlined, and synthesis occurs.
Prophase
The nuclear envelope dissolves and the chromosomes thicken, comes after interphase.
Metaphase
The 3rd stage in which spindle fibers are formed, and the chromosomes line up in the middle.
Anaphase
The 4th stage in which the synthesis is undone, going from 2n –> 1n. The chromosomes move to the poles.
Centriole
Helps to develop spindle fibers during mitosis
Telophase
The chromatids move to the poles of the cell, the nuclear envelop reforms and the cell plate/membrane reforms.
Homologs
Holds genetic information, and the shared ancestry between others.
Bivalents
A pair of homolog chromosomes
Mitotic Apparatus
Separates sister chromosomes in a daughter cell.
Spindle Fibers
Microtubules that are spiraled during mitosis.
Haploid
Single set of unparied chromosomes
Diploid
Contains two sets of chromosomes, from parents.
Cell Plate
Forms between the two nucleus during the telophase.
Furrow
An indent on the cells surface.
