How many Chromatids make 1 chromosome?
What is 2?
The 3 checkpoints for a cell cycle is after G1, after G2, and after anaphase.
What is False?
The third check point is after metaphase.
What phase does a cell spend most of it's life?
What is interphase?
What are the general and specific steps of the cell cycle?
General- Interphase, Mitosis, Cytokinesis
Specific Steps: G1, S, G2, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
What is the latin meaning of the prefix 'ana' ?
What is to move back?
What proteins complex surrounds the area that links a pair of sister chromatids together during cell division ?
What is a kinetochore?
The process of the cell cycle essentially duplicates a cell to create two daughter cells.
What is true?
What phase does the alignment of chromosomes occur?
What is metaphase?
Why is it important for cells to divide?
What is to be able to repair damages as well as to allow our body to grow?
What does the 'G' in G1 and G2 stand for?
What is gap?
What is the difference between a chromatin, chromatid, and a chromosome?
Chromatin= a microscopic level of DNA when it is scrambled
Chromatid= when DNA condenses a little more; visible under microscope
Chromosome= made up of 2 chromatids
A plant cell's cytokinesis is the same as an animals cell?
What is false?
Vesicles contain cellulose that help produce a new cell wall (that is how two cells are created).
What phase does the nuclear membrane reappear?
What is telophase?
DNA is a type of what?
What is a nucleic acid?
What is the definition of cytokinesis?
What is cell movement?
Spindle fibers originate from what, which is composed of tubulin.
Hint: Found in cytoskeleton
What is microtubules?
The number of chromosomes doubled in the prophase of mitosis and halved in the anaphase of mitosis.
What is false?
The spindle fibers sperate the two chromatids from the centromere so it isn't "halved".
What stage do most neurons remain in for the entirety of their life?
What is G0?
What occurs in the Interphase phase and why is this important?
What is the cell grows bigger, replication of DNA and duplication of organelles. This allows the cell to be able to have enough to divide in cytokinesis.
What is the latin meaning of 'telo' ?
What is to end/the end ?
What is the name for the special region on a duplicated chromosome that holds the sister chromatids together?
What is the centromere?
The misalignment of the chromosomes in metaphase can create a daughters cell that has extra chromosomes and one that has less chromosomes.
Whet is true?
This can lead to death, organic disease or even cancer
What is G2?
A ____ fiber tighten around the two cells in cytokinesis to split it.
What is an actin fiber?
Define Mitosis ?
What is aa type of cell division that results in two daughter cells?
