10 Questions
Which type of bond is responsible for stabilizing the primary structure of a protein?
Peptide bond
What is the main difference between denaturation and degradation of proteins?
Denaturation unfolds the protein without affecting the primary structure, while degradation breaks down the primary structure.
Which enzyme adds a phosphate group to a compound?
Kinase
What is the common suffix for most enzymes that are proteins?
-ase
Which molecule forms a hairpin, single-stranded structure with self-complementary sequences?
DNA
What is the composition of a nucleoside?
Sugar and nitrogenous base
Which molecule contains a phosphate group on the 2' carbon and follows Chargaff’s rule?
DNA
Which structure is formed by the polymer of ribonucleotides linked 3’ to 5’ by phosphodiester bonds?
rRNA
Which molecule's presence does not follow Chargaff’s rule, and lacks oxygen group on the 1st carbon?
RNA
Which nucleotide reveals the presence of single, double, or triple phosphorylated forms?
(deoxy)Adenosine monophosphate (AMP)
