Cell Cycle
What is the longest phase of the Cell Cycle?
Interphase
How many cells does mitosis produce?
2
How many divisions does meiosis have? How many cells does it produce?
2 divisions for a total of 4 cells
When DNA and the proteins associated with it condense, what is formed?
Chromosomes
Stimulate the growth and division of cells.
growth factors
In what stage in the cell cycle is DNA replicated?
The S-Synthesis phase
These are the 3 reasons for mitosis or regular cell division
growth, development, and repair
What types of cells does meiosis produces ?
gametes
What is an advantage of sexual reproduction over asexual reproduction?
increased genetic variation
Cells that do not respond to the signals that regulate the growth of most cells
Cancer cells
How is the cell cycle regulated?
What is Cyclin?
What is the first phase of Mitosis and what is happening.
Prophase, the chromatin condense into chromosomes and the nucleoli disappears, the mitotic spindle is formed
independent assortment of homologues occurs in what stage of meiosis?
Metaphase I
This is a duplicated chromosome consisting of two of these structures held together by the centromere
chromatids
Unicellular organisms use this process to divide/reproduce
binary fission
Interphase consists of which stages of the cell cycle?
G1, S, and G2
If a cell has 46 chromosomes and undergoes mitosis, how many chromosomes will each resulting cell have?
46 chromosomes
There are 20 chromosomes in an animal cell about to divide. How many chromosomes will there be in its daughter cell after Meiosis?
10 chromosomes
what are the three factors that contribute to genetic variation?
What is crossing over, independent assortment of homologues, and random joining of gametes.
Which process that occurs during prophase I of Meiosis can be described as homologous chromosomes wrapping around each other?
crossing over
what are the five phases of mitosis in order
prophase, prometaphase, metaphase, anaphase, and telophase.
Mitosis occurs in what kind of cells?
somatic cells
A cell that has two complete sets of chromosomes is called…
diploid cells
Describe the law of independent assortment
When two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together
Explain why the cell spends so much time outside of Mitosis.
It takes a long time for the cell to prepare and grow in order to do cell division.
