Please don't copy Chemistry All of the following tend to favor a helical conformation of a single polynucleotide chain EXCEPT: Group of answer choices A. hydrophobic interactions of the rings of the purine and pyrimidine bases that exclude water. B. charge–charge repulsion of phosphate residues of the polynucleotide backbone. C. hydrogen bonding between appropriate purine–pyrimidine pairs. D. interchange of electrons in the p orbitals of the purine and pyrimidine bases.

I have a question about ''complementary nucleotides''. Books and google makes me confused. Correct me if Im wrong. Everywhere I read, it says ''nucleotides in basepairing are complementary''. But the basepairing are part of the nucleotides structure? shouldnt the basepairing in nucleotides be complementary, meaning the bases have been linked together via hydrogen bonding, which results in the shape of nucleotides???? Or do they mean that, nucleotides are complementary because their bases have formed bond with each other, which gives the shape of nucleotides?? I dont know why I dont get it. Please explain so I can understand it. Thank you
Predict the secondary and tertiary structure of the following peptide sequence: a.) LKAENDEAARAMSEA b.) CRAGGFPWDQPGTSN 2.) In an experiment, you somehow added cysteine so that it would covalently bond a protein complex composed of two proteins. But, the problem is you can’t detect the bridge, meaning you can’t detect covalent bond formation of cysteine in between two proteins. How do you generate disulfide bond? Give an idea to force disulfide bond formation between two proteins. 3.)Lysozyme consist of 4 disulfide bridges while Bovine Serum Albumin(BSA) is 17. However, lysozyme is more rigid compared to BSA. Why? What are the factors affecting the rigidity of their structures? Does the number of α-helixes and β-sheets matter?
