BIOCHEM MODULE 6 EXAM 2026
ACTUAL QUESTIONS WITH VERIFIED
ANSWERS.
Briefly describe how non-covalent interactions contribute to the
3D shapes and structures of RNA molecules. - correct answer-
Non-covalent interactions contribute to the 3D shape and
structures of RNA molecules by allowing RNA to fold on itself
via hydrogen bonding between complementary base pairs.
Nucleotides interact with complementary resides to produce a
secondary structure.
In one sentence, identify the most noticeable difference
between between the A-form and Z-form of DNA. - correct
answer-The Z-form of DNA is left-handed, while the A-form of
DNA is right-handed.
In nucleic acid chemistry, compounds that contain an organic
nitrogen-containing base, sugar, and phosphate group are
called _(A)_. - correct answer-(A) nucleotides
Two purines found in DNA are _(B)_ . - correct answer-(B)
adenine and guanine
, A pyrimidine found in all RNA, but not in DNA is _(C)_. - correct
answer-(C) uracil
In DNA, the pair _(D)_ is held together by 3 hydrogen bonds. -
correct answer-(D) cytosine and guanine
In DNA, the pentose _(E)_ serves as the monosaccharide. -
correct answer-(E) 2-deoxyribose
The monomers of RNA nucleic aids, called nucleotides, consist
of 3 parts. What are those 3 parts? - correct answer-A base,
ribose, and phosphoric acid.
Identify the following structure. - correct answer-guanine
(purine)
Identify the following structure. - correct answer-adenine
(purine)
