BIOS 100 EXAM 3
1. Which of the following statements is incorrect regarding DNA and RNA?-
: All of these are correct:
DNA is double stranded, and RNA is a single strand.One of the bases is different.
They each contain a slightly different sugar molecule.They are found in different locations in
the cell.
All of the above are correct.
2. After DNA replication, .: each of the two daughter DNA molecules
contains one strand from the original DNA molecule and one newly synthesized strand
3. Drag the terms to their correct location:
4. Part A - Nucleotide pairing:
5. Can you identify the molecules and processes involved in the flow ofgenetic information
through a cell?:
6. Part B Part complete
Using the figure, can you complete the sentences about the structures andprocesses involved
with the flow of information through the cell?
Drag the terms on the left to the appropriate blanks on the right to completethe sentences.:
7. Can you identify the type(s) of nucleic acid to which each of the followingstructures
belong?
Part A
Part complete
Drag the structures associated with nucleic acids to the appropriate bins.:
8. Can you identify the steps in which the lagging strand is synthesized? To review DNA
replication, watch this BioFlix animation: DNA Replication.Part A - Lagging strand synthesis
Part complete
Drag the labels onto the diagram to identify the stages in which the lagging strand is
synthesized.:
9. Can you identify the type(s) of nucleic acid to which each of the following structures
belong?
Part A
Part complete
Drag the structures associated with nucleic acids to the appropriate bins.:
, 10. Part complete
Drag each term to its correct location in this concept map about mutations.:
11. Which of the following mutations is LEAST likely to result in harmfulchanges to cellular
proteins?: Silent mutations
12. Can you correctly identify the steps in the polymerase chain reaction(PCR)?
Part A
Part complete
Drag the labels to the appropriate locations on this diagram.:
13. PCR is used to copy just a relatively small region of DNA, not the entire genome. How
do researchers specifically target the region of interest? See Section 6.16 (Page) .: They use
two primers, each about 15 to 20 nucleotides long,that flank the region of interest.
14. Can you place the steps involved in creating genetically modified organ-isms in their
proper order?
Part A
Part complete
Drag the labels to the appropriate locations on this flow chart.:
15. Because bacterial chromosomes are circular, human proteins cannot beproduced in
bacterial cells. See Section 6.13 (Page) .: False
16. What do you call an organism that has been genetically engineered tocontain a gene from
a different species?: transgenic
17. One genetic engineering application that relies on transgenic organisms is the production
of large quantities of a desired protein, such as the humaninsulin protein. This process
involves the use of restriction enzymes that actlike molecular scissors to cut out the gene of
interest. Another enzyme calledligase "glues" the gene into the target DNA.
Drag the steps of gene cloning into the correct sequence.:
18. How does a scientist get the corrected version of a gene into the cells ofa gene therapy
patient?: It is delivered with a modified virus.
19. Can you fill in this paragraph about the human genome?Part A
Part complete
Drag the terms to their correct locations in the paragraph. Not all terms willbe used.:
20. Can you correctly place the labels in this diagram that summarizes theprocess of DNA
profiling?
Part A
