Nucleotide -
correct answer ✅monomer of nucleic acids made up of a 5-
carbon sugar, a phosphate group, and a nitrogenous base
Nucleoside -
correct answer ✅base + sugar
,Biochemistry Test 1 (Essential
Biochemistry 3rd Edition) Exam Actual
Questions and Answers 2026
sugar-phosphate backbone -
correct answer ✅The alternating chain of sugar and phosphate to
which the DNA and RNA nitrogenous bases are attached
nucleotide residue -
correct answer ✅Each nucleotide that has been incorporated into
the polynucleotide
degradation -
correct answer ✅breaking of linkages

correct answer ✅binding site has a structure complementary to
the substrate it needs to bind
BDNA -
correct answer ✅most frequent structure of DNA; right handed
helix; can fold into higher order structures (first step is supercoil);
anti glycosidic bond; 35 Angstrom pitch per turn of helix
, Biochemistry Test 1 (Essential

Questions and Answers 2026
ZDNA -
correct answer ✅left-handed double helix, less abundant
Distance between backbones -
correct answer ✅Kept constant due to every rung being a H bond
between a pyrimidine and purine
Pyrimidines -
correct answer ✅cytosine, thymine, uracil (single ring structure)
Purines -
correct answer ✅Adenine and Guanine, double ring structure
Major Groove -
correct answer ✅a groove that spirals around the DNA double
helix; provides a location where a protein can bind to a particular
sequence of bases and affect the expression of a gene
minor groove -
correct answer ✅A smaller groove that spirals around the DNA
double helix.
