Some regions of protein secondary structure are described as "random coil". This designation is misleading because: A. the secondary structure must always be an alpha helix or beta sheet. B. although the structure is indeed random, it need not necessarily resemble a "coil". C. although the region may be unique to a particular protein, it is not random: each cellular copy of that protein will contain an identical "random coil" structure that corresponds to the same portion of primary sequence....

QUESTION 2 Select the CORRECT statements (chose all that are correct). Secondary protein structures are held together by disulphide bridges/bonds. Alpha helices and beta sheets are common secondary protein structures. Tertiary protein structures are held together by covalent bonds only. Secondary protein structures are held together by hydrogen bonds only. All proteins have a quaternary protein structure. Amino acids linked with a peptide bond make up the primary protein structure.

Question 10 (4 points) Although all protein structures are unique, there are common structural building blocks that are referred to as regular secondary structures, Some proteins have alpha-helices, some have beta-sheets, and still others have a combination of both. What makes it possible for proteins to have these common structural elements? 12 15 a) the hydrophobic-core interactions. b) hydrogen bonds that form along (alpha helices) or between (beta sheets) polypeptide backbones. c) side-chain interactions d) specific amino acid sequences. 7...

Which of the following is true of secondary structure in protein folding? Pick ALL that apply. A. It involves hydrogen bonding. B. It involves the side chains. C. It involves hydrophobic interactions. D. It results in alpha helicies with the side chains hidden inside the helix. E. It results in beta-pleated sheets with side chains sticking out of the plain of the sheet. F. It involves the peptide backbone.

Question 1 1 pts Why is it important for DNA to have complementary base pairing? O Complementary base pairing allows base pairs to be packed in the most energetically favorable arrangement inside of the double helix structure. O Complementary base pairing will pair a purine with a purine, which are a similar width, thus they are able to hold the sugar-phosphate backbone an equal distance apart along the DNA molecule o Complementary base pairing is only important for maintaining the...
