What is responsible for the primary structure of proteins?
Peptide (covalent) bonds
What are the traditional nitrogenous-base pairings for DNA?
A to T and G to C

When and where are TA Emma Lou Pakulniewicz's office hours?
Tuesdays 1:30-3:00pm and Thursdays 2:30-4:00pm, both in PLSB 300
What interactions and/or bonds are involved in the tertiary structure of proteins?
intra-disulfide (covalent), hydrophobic interaction ~ van-der Waals (formed between non-polar), ionic, and H-bonds
What is the structural difference between a ribose sugar and deoxyribose sugar?
Ribose sugars have OH at both 3’ C and 2’ C, while deoxyribose have OH only at 3’ C
What is the difference between an intramolecular disulfide bond and an intermolecular disulfide bond in the context of protein structure?
Intramolecular (within molecule) is stabilizing of tertiary structure, while intermolecular (between molecules) is stabilizing of quaternary structure
When and where TA Kevun Willis' office hours?

What group(s) is/are ionized on an amino acid at a pH of 13 and is the overall charge?
Carboxyl group is ionized while the amino group is neutral - overall charge is -
Why is DNA synthesis in the 5' to 3' direction?
DNA polymerase can only add new nucleotides to the free hydroxyl (-OH) group located at the 3′ end of a growing DNA strand
Which is more likely to be disrupted by heat, a hydrogen bond or a covalent bond?
Hydrogen bond
