BIOD 102 – LAB EXAMS 1 - 6

Lab 1 Exam-

Question 1
Multiple Choice:

Which of the following is transcribed from DNA and contains instructions for a protein?

cDNA

tRNA

mRNA(~00:16)

RT


Question 2
Describe the flow of genetic information within the cell.
Answer: DNA → RNA → Protein (~ 00:18)

Question 3
What are DNA microarray assays?
Answer: DNA microarray assays are a collection of single-stranded DNA fragments that represent
various genes (~2:23).

Question 4
What does each well in a microarray analysis contain?
Answer: Each well contains identical copies of DNA fragments that carry a specific gene (~4:21).

Question 5
Which of the following genes encodes for a protein in the polyamine biosynthesis pathway?
FGG
SIAT9
CYP24
ODC1 (~5:11; Microarray Table file)

Question 6
If the results of a microarray analysis conducted in a research laboratory showed that a gene turned green, what
would this indicate about the gene?
Answer: The color green indicates that the gene is expressed (transcribed) more in normal lung cells than
in cancer cells (~ 5:21; Microarray Table file).

Question 7

,True or False: Transcribing a gene means that it is turned
“off”. False; Transcribing a gene means that it is turned “on”
(~6:33).

Question 8
True or False: Tumor suppressor genes promote cell growth, cell division, and cell proliferation.
Answer: False; Oncogenes promote cell growth, cell division, and cell proliferation (~7:02)

, Question 9
Multiple Choice:

DNA is into mRNA, which is then into proteins.
transcribed; translated(~6:07)
