QUESTION 1 The full name of this amino acid is The 3-letter abbreviation is Please also note the following: • The non-ionized structure is shown • Spelling matters • For the acidic amino acids use the full name, e.g. "so-and-so acid" • Case does not matter • Do not include L- or D- in the name НООС- СH - NH2 CH3
QUESTION 23 Most proteins that are anchored to the cell membrane receive this modification: O Lipidation O Ubiquitylation Glycosylation O Phosphorylation
Question 7: Peptide nucleic acids (PNAS) exhibit greater stability as heteroduplexes with DNA (ie PNA-DNA duplex) than does double-stranded DNA (i.e. DNA-DNA duplex). However, peptide nucleic acids lack charged groups, making them largely insoluble under near-physiological conditions in aqueous buffer. Provide (1) an explanation for the increased stability of PNA-DNA duplexes (hint: consider intermolecular forces). (2) Additionally, propose modification(s) of the PNA scaffold DNA that could increase solubility without drastically reducing duplex stability. PNA R1 HN но.

QUESTION 25 Which of these characteristics does not describe the ß sheet? Amino acid side chains are located both above and below the sheet. B sheets have a pleated edge-on appearance. The sheets contain as few as two and as many as 22 polypeptide chains. Parallel B sheets containing fewer than five chains are the most common. They can exist in either parallel or antiparallel configurations.
