Chapter 9, Problem 24CONQ
Summary Introduction
To review:
Amino acids in the protein are good for interacting with the DNA.
Introduction:
DNA is a deoxyribonucleic acid, which is formed from the several units of polynucleotide chain. During the process of translation, nitrogen bases forms group of three which is called triplet. Sequence in triplet which codes for protein is sequence of amino acid.

The structure of an alpha helix orients the oxygens of the carbonyl group of the peptide bond towards the C-terminal end of the helix while the hydrogens of the NH groups orient toward the N-terminal end, thus imparting a dipole along the length of the helix. As a result, which kinds of amino acids would favor the C-terminal end, and which would favor the N-terminal end?
negatively charged, positively charged
positively charged, negatively charged
negatively charged, hydrophobic
positively charged, hydrophobic
hydrophobic, negatively charged

- In DNA the nucleic acid bases form hydrogen bonds between them, which are responsible for the formation of the double-stranded helix. A hydrogen bond donor is defined as any hydrogen atom that can participate in a hydrogen bond, whereas a hydrogen bond acceptor is defined as any atom that can “receive” that hydrogen atom to form a hydrogen bond.
