It is broken apart into its constituent amino acids d It becomes all o-helix e All of the above 38 Whichoftho foloweg amro acids is urikely to be fund n an ohelir? apn a phenylalanine b tryptophan c proline d. lysine

Explanation / Answer

33.Correct answer is:c.tertiary structure

Reason:Disulfide bonds or bridges that are formed between cysteine residues are important for tertiary protein structure.

34.Correct answer is:a.covalent bonds

Reason:Primary protein structure involves peptide bonds that are covalent bonds.

35.Correct answer is:True

Reason:A single change in aminoacid will form a malfuntioned protein.

36.Correct answer is:c.Cys

Reason: Hydrogen bond in alpha helix is formed between N-H of one aminoacid with C=O of an aminoacid that is present four residues earlier to it.

37.Correct answer is:a.its secondary structure is disrupted but its primary structure remains intact.

Reason:Denaturation disrupts secondary,tertiary and quaternary structure of protein but retains the primary structure.

38.Correct answer is :C.proline

Reason:Due to its cyclic structure, proline is unlikely to be part of alpha helix.
