MITOSIS 1
Holds our genetic information
What is DNA?
The 2 parts of the X-shaped chromosomes have this "sibling" name
sister chromatids
Mitotic spindles are formed in these cell parts
What are centrioles?
This is the phase before the start of mitosis
What is interphase?
What is the process by which a eukaryotic cell divides into two identical daughter cells?
What is mitosis?
DNA replication occurs during this phase.
What is the S phase (Synthesis phase)?
The cells splits in two during this stage.
What is Cytokinesis?
During this stage, the nuclear membrane reforms
What is telophase?
The cell grows during these two phases in interphase?
What is G1, G2
These are the 3 stages of interphase, in order.
What is G1, S, and G2?
These are the thread-like structures that become microscopically visible in the cell nucleus as distinct x-shaped entities after DNA is replicated?
What are chromosomes?
Humans have this many chromosomes in their body cells
What is 46?
In this mitosis stage, the chromosomes move toward to the poles of the cell
What is anaphase?
An apparatus of microtubules that resemble strings that controls chromosome movement during mitosis
What are spindle fibers?
In this stage of mitosis, the chromosomes align in the middle or equator of the cell
What is Metaphase?
The term for DNA that is in its least condensed form
What is Chromatin
What are the 4 phases of mitosis, in correct order?
Prophase, Metaphase, Anaphase, Telophase
This forms between 2 animal cells during cytokinesis that helps them split apart.
What is a cleavage furrow?
This many cells arise from a single cell after the completion of mitosis and cytokinesis?
What is two cells?
The resulting daughter cells of mitosis contain this number of chromosomes
What is 46
The area within the centromere where spindle fibers attach to chromosome
What is the kinetochore region?
What does the cell check for during the G2 checkpoint?
For mutations in DNA after replication and that all DNA has been replicated properly
the chromosomes start to condense in this phase but they aren't fully condensed until prophase
What is G2 of interphase?
This is the thing that forms between 2 PLANT cells during cytokinesis
What is a cell plate
At the completion of this phase, the mitotic spindles are checked for connection with the kinetochore of the chromosome's centromere?
What is metaphase?
