What Does it Start with? Review CHAPTER 10 Cell Cycle
1.Cell division in eukaryotes consists of two parts: M ______which divides the chromosomes
and C ______which divides the cytoplasm.
2.Bacteria divide using B ______F ______instead of mitosis.
3.A C ______is made up of two C ______arms joined in the
middle by a C ______.
4.G1, S, and G2 combine to make up I ______, the non-dividing phase of the cell
cycle.
5.When cells like nerve cells are in G0, they leave the cell cycle and S ______dividing.
6.DNA is copied during the S ______or S phase of interphase.
7.P ______is the first phase of mitosis during which C ______scrunches into chromosomes, the C ______and S ______fibers appear to pull the chromosomes, and the N ______M ______and
N ______disappear.
8.During M ______the chromosomes line up along the center of the cell.
9.In A ______the chromatid arms separate and move to opposite ends of the cell.
10.T ______is also called reverse P ______because all of the events that happen in prophase are “undone” in telophase.
11.H ______chromosomes are the same size and the same shape and carry genes for the same traits but are NOT identical.
12.The region near the nucleus where the centrioles are found that helps organize the spindle fibers during cell division is called the C ______.
13.C ______are log-like structures that appear near the nucleus during cell division in an animal cell and move to opposite poles to pull the chromosomes apart.
14.The S ______fibers are made of M ______and connect each chromosome to the centrioles.
15.The family of proteins that regulate the cell cycle in eukaryotic cells is called C ______.
When DNA and its attached proteins is spread out in the nucleus of non-dividing cells it is called
C ______. When it is scrunched up in dividing cells it is called
C ______.
16.The disease in which one of the body’s own cells loses the ability to control division C ______
17.When animal cells undergo cytokinesis they use a C ______F ______to split their cytoplasm, but plant cells use a C ______P ______because their cell wall keeps them from pinching.
18.The repeating steps a cell goes through during its lifetime are called the C ______C ______.
19.The spread of cancer cells to a new location in the body is called M ______.
20. Two types of cell regulators are I ______& E ______
21. Two types of tumors are B ______& M ______
22. C ______are substances that can damage the DNA and cause cancer.
Ch. 12 DNA STARTS WITH ? Name ______
1. DNA that is spread out in the nucleus of a non-dividing cell so it can be read is called
_C______.
2. In dividing cells, the DNA is scrunched into _C______so it can be moved.
3. Adenine, thymine, guanine, cytosine, and uracil are all _N______B______.
4. Chromosomes are made when DNA wraps around _H______to make bead-like structures called _N______.
5. The process of making a DNA copy is called _R______.
6. _N______A______(like DNA and RNA) are made by joining
_N______subunits together in a chain.
7. _U______is the nitrogen base NOT found in _D_ __ __ and _T______is the nitrogen base NOT found in _R_ __ __.
8. Nitrogen bases made with _O_ __ __ ring are called _P______and nitrogen bases made with _T_ __ __ rings are called _P______.
9. James _W______and Francis _C______are the scientists who used
Rosalind _F______’s X-ray images to figure out that DNA is shaped like a “twisted
ladder” with _P______and _S______forming the sides of the
ladder, _N______bases forming the rungs, and _H______bonds acting as “glue” to hold the two sides together.
10. In _G______’s mice-pneumonia experiment, lethal bacteria passed genetic material
to harmless bacteria in a process called _T______.
11. According to _C______‘s rules when making DNA, _A______always
bonds with _T______and _C______always bonds with
_G______.
12. Viruses that infect bacteria (like the one used in _H______- _C______‘s
blender experiment which proved DNA was the genetic material) are called
_B______.
