E.)
a, b and c
Coronavirus has the enzyme __________
(A. Reverse Transcriptase, B. Replicase, C.DNA polymerase, D.
RNA polymerase),
which is a ______________
(A. RNA Dependent DNA Polymerase, B. DNA Dependent DNA
Polymerase, C. DNA Dependent RNA Polymerase, RNA Dependent RNA
Polymerase.
This allows it to make new copies of its genetic material.
The polymerase that synthesizes which of the following molecules
uses RNA as a template and synthesizes new stands from 5' to
3'?
1. Neither RNA polymerase nor DNA polymerase
2. both RNA polymerase and DNA polymerase
3. DNA polymerase only
4. RNA polymerase only
Compare the proofreading mechanisms of DNA and RNA polymerase.
Specifically,
which active site is required for proofreading by each enzyme and
what are the products of
this activity?
One way to discover promoters is through an experiment called
RNA polymerase protection assay, in which RNA polymerase binds to a
gene, is cross-linked to the DNA, and then the DNA is subjected to
fragmentation, which breaks apart any DNA that is not protected by
cross-linked protein. Explain why this would help to identify
promoters in genes.
10. (1 pt) For which of the following situations is the
dependent groups t-test appropriate (if not appropriate,
why?)
a. The IV is presence or absence of conversation
directed to comatose patients (same patients with and without
conversation); the DV is the patients’ intracranial
pressure.
b. The IV is birth type (home vs hospital); the DV is

hours after surgery.
c. The IV is time since incarceration for...
