Mitosis Chapter 19 Flashcards
Assist in the transmission of genetic information from one generation to the next
chromosome
these makeup a chromosomes. They are two identical parts
sister chromatids
A display which shows chromosomes arranged in pairs
karyotype
An orderly process composed of interphase and cell division
cell cycle
DNA and proteins
chromatin
the cell doubles its organelles to prepare for cell division
G1 stage
A copy is made of all the DNA in a cell
S stage
The cell buikds all the proteins needed for cell division
G2 stage
Holds the chromatids together
centromere
The cell spends most of its time in this phase
interphase
The division of the cytoplasm
cytokinesis
Division of the nucleus
mitosis
The checkpoint where the cell is committed to divide
G1 checkpoint
At this checkpoint, the cell verifies DNA has been replicated
G2 checkpoint
Programmed cell death
apoptosis
T/F The more chromosomes an organism has, the more complex it is
false
T/F 22 of 23 chromosome pairs in humans are autosomes
True
T/F All cells in the human body undergo mitosis
False
The cell that divides is called the
parent cell
The new cells are called
daughter cells
Presence of 2 complete sets of chromosomes in an organism’s cell, each parent contributing a chromosome to each pair
diploid (2n)
Presence of a single set of chromosomes in organism’s cells
duplicates the centrosome
haploid (n)
Assembles the microtubules that make up the spindle fibers
Mitotic spindle
Mitosis is a form of ________ reproduction
asexual
