Mitosis
The purpose of mitosis is this.
To get exactly one copy of each chromosome to each daughter cell.
During Metaphase 1, these align on the metaphase plate.
What are tetrads?
From one parent cell in MITOSIS, this many daughter cells are created, and from one parent cell in MEIOSIS, this many daughter cells are created?
What are 2 (mitosis) and 4 (meiosis)?
During reproduction in humans, the process of fertilization combines two haploid gametes to make this.
What is a Diploid (2n) gamete?
Growth factors are present in this phase of the cell cycle.
What is the G1 phase?
During metaphase of mitosis, these are what is lined up at the metaphase plate.
What are chromosomes?
These separate from each other during anaphase 1.
What are homologous chromosomes? (from each other)
How many S phases in mitosis? meiosis?
What is one (in both)?
The 46 chromosomes during reproduction come from these places.
what are 23 from a sperm cell, 23 from an egg cell?
Cancer can be defined as this.
What is mutations that cause errors in gene expression of cell cycle proteins OR lack of regulation?
During this step of mitosis, the nuclear envelope dissolves.
What is prophase/prometaphase?
If n=8, there are this many tetrads lined up on the metaphase plate during metaphase 1. How many duplicated chromosomes is this?
What is 8 tetrads, and 16 chromosomes?
Prokaryotic cell division is known as this.
What is (binary) fission?
There are this many chromosomes in each cell of a human zygote and blastocyst.
What is 46?
What is the cytoskeleton?
The number of types of chromosomes is N in a given cell. For this example, n=12. How many double helices of DNA are there during G2 of the mitotic cell cycle?
what is 48?
In between Meiosis 1 and Meiosis 2, Interphase 2 occurs sometimes, but THIS doesn't happen.
What is chromosomes do NOT duplicate again?
Name an advantage of sexual reproduction.
What is that it creates genetic diversity?
State what happens in the S phase of the cell cycle.
List all steps of mitosis (including what happens before). Briefly explain what happens in each one.
What is Interphase - growth and regulation),
Prophase (centrosomes line up) Metaphase (line up in center of cell) Anaphase (start to separate) Telophase (chromatids are separated) Cytokinesis (fully separated)?
These are exact copies of each other. Explain why.
What are sister chromatids, because they are formed during replication of the DNA in S phase?
Define cytokinesis in animal cells vs plant cells.
What are: animal cells - cleavage furrow, and plant cells: new cell plate?
Name the three primary examples of asexual reproduction.
Name three times that cells need to divide.
What are: wound repair, replacement of dead cells, growth and development, cancer, and when single celled organisms make more individuals?
