Homework Answers
1. Option C is the correct answer.
Hydropathic index of an amino acid represents the hydrophobicity/ hydrophilicity of its side chain. It is measured by the number. Greater the number greater the hydrophobicity of side chain. Since the hydrophobic segment hate the aqueous environment it is present internally into three dimension shape of protein while hydrophilic segment present on surface.
2. Option D is the correct answer.
Tertiary structure of proteins involves interactions such as ionic (salt bridges) and hydrogen bonds, disulphide bonds, and both hydrophobic & hydrophilic bonds.

QUESTION 9 Sequence analysis of a membrane protein shows four 20 amino acid long stretches of residues that are predominantly hydrophobic Between each of these stretches of hydrodophobic residues, a stretch of predominantly hydrophilic residues is found. From this observation one can reasonably postulate that: A this is a 4 stranded beta barrel which spans the membrane B.this is a glycoprotein o this protein has 4 alpha helical segments that span the membrane o this protein can be removed from...
