In proteins, the hydrogen bonding responsible for the secondary structure of a protein generally takes place between backbone carbonyl oxygen atoms and amide hydrogen atoms. In contrast, the hydrogen bonding that contributes to tertiary structure generally occurs between amino acid side chains. Two serine residues are shown below, with possible hydrogen bonds shown in green. Which bonds depict the hydrogen bonding that occurs between serine residues and contributes to tertiary structure?

Compare and contrast the bohr model and the electron cloud models of the atom.

What are the similarities of physical and chemical change ?

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
