2
Genes that code for particular polypeptides.
3
What are structural genes?
4
DNA segment that serves as the binding site for
an inhibitory protein that blocks transcription.
5
What is an operator?
6
A protein that inhibits a specific gene from
being expressed.
7
What is a repressor protein?
8
DNA segment that recognizes the enzyme RNA
polymerase and promotes transcription.
9
What is a promoter?
10
DAILY DOUBLE
11
A molecule that initiates gene expression.
12
What is an inducer?
13
The site of active transcription of DNA into RNA
the uncoiled form of DNA.
14
What is euchromatin?
15
A form of mRNA that contains both introns and
exons.
16
What is pre-mRNA?
17
The sections of a structural gene that do not
code for amino acids and therefore are not
translated into proteins.
18
What are introns?
19
What are spliced together and leave the nucleus
to begin protein synthesis?
20
What are exons?
21
A noncoding control sequence that facilitates
transcription in a eukaryotic cell.
22
What is an enhancer?
23
Non-threatening type of tumor whose cells remain
within a mass.
24
What is benign?
25
The spread of cancer cells beyond their original
site.
26
What is metastasis?
27
Type of cancer that grows in bones and muscle
tissue.
28
What is a sarcoma?
29
Solid tumors that grow in the tissues that form
blood cells.
30
What are lymphomas?
31
Normal cells will stop dividing when they become
too crowded usually after this many divisions.
32
What is 20-50 cell divisions?
33
Regulatory proteins that ensure that the events
of cell division occur in the proper sequence and
at the correct rate.
34
What are growth factors?
35
Any substance that increases the risk of cancer.
36
What is a carcinogen?
37
Agents that cause mutations to occur within a
cell.
38
What are mutagens?
39
Mutations in these are passed along to offspring.
40
What are gametes?
41
Cancer risk increases with these two things.
42
What is age number/amount of exposures to
carcinogens?
43
A gene that causes cancer or other uncontrolled
cell growth.
44
What is an oncogene?
45
Genes that code for proteins that prevent the
uncontrolled rate of cell division.
46
What are tumor-supressor genes?
47
Genes that control a cells growth and
differentiation.
48
What are proto-oncogenes.
49
Causes a normal gene to turn into an oncogene.
50
What is a mutation?
51
Can accelerate the rate of cell division in the
host cell.
52
What is a virus? (May stimulate uncontrolled
growth in host cell by causing mutations in
proto-oncogenes or tumor- repressor genes, or may
activate the cells own oncogenes.)
