BIOCHEM C785 OA READINESS CHECK
FULL SOLUTION PACK(Everything needed
to pass Biochem c785 is here)
Biochemistry Readiness
Check
The 2nd OA Readiness Check is designed to give you additional practice
with new assessment-style questions to help prepare for success on the
OA. Thus, please try to mimic exam-like conditions by taking the test in
one <2 hr sitting without any study aids apart from your
whiteboard/scrap paper. Note: Responses cannot be edited. You will be
able to see the results and feedback after submitting the test. A score of
70% is required for OA approval. If you score below 70%, please speak
with a Course Instructor via appointment to discuss next steps prior to
retaking this test.

What is the complementary sequence to 3’ ATG CGA ATA 5’?
(1/1 Points)
3’ TAT TCG CAT 5’
The correct answer is 3' TAT TCG CAT 5'. Remember complementary means
“Matching or Pairing” You have to remember to pay attention to your numbers
as well as your letters (A-T, G-C, 5'-3'). The correct answer is 3’ ATG CGA ATA 5’
(original sequence) 5’ TAC GCT TAT 3’ (complementary sequence) But we asked
for it in the 3’ direction, so mirror answer to give correct answer: 3’ TAT TCG CAT

Ser Val Ile
The correct answer is Ser Val Ile because 5’ TAT TAC CGA 3’ template is
complementary and antiparallel so 3’ AUA AUG GCU 5’ but it is in the wrong
orientation, so mirror 5’ UCG GUA AUA 3’ and read the chart Ser Val Ile

Which of the following are the correct components for a PCR reaction? (1/1 Points)
dNTPs, Primer, RNA Polymerase, template RNA
dNTPs, Primer, DNA Polymerase, template DNA
The correct answer is dNTPs, Primer, DNA Polymerase, template DNA. Notice that
all
components are about DNA. The Primer is even a DNA Primer.
ATP, Primer, mRNA polymerase; template mRNA
Acetyl CoA, RNA primer, DNA Ligase, Template phosphate

Which of the following would represent a silent mutation if this is the original sequence: 5’ AUC GU

The correct answer is 5' AUC GUA ACA 3' Ile Val Thr
, 4
5’ AUG GUA ACA 3’
5’ AUC GCA ACA 3’
True
The correct answer is Option 1 because an autosomal dominant disorder
would be inherited on numbered chromosomes, not sex chromosomes X or Y.
Also, at least one dominant allele (yellow box) needs to be present for the
individual to have the dominant disease.
False

This learning objective is now tested in a different WGU course than Biochemistry. Please select Tru
True
The correct answer is X- linked recessive because parents (carriers) do not have
it (II-5- 6) but a child does (III-5). You will get the same result if you consider
parents (carriers) (I-1-2), who do not have the trait, but a child does (II-3). A third
option that gives the same result (X-linked recessive) is by considering parents
(carriers) who do not have the trait (III-1-2), and their child does (IV-1). The
pattern is recessive because the selected parents are carriers, and it is X-linked
because only males have the trait.
