Proline and glycine both disturb the symmetry of α-helix which of the following are true regarding to these two amino acids

a) proline changes the orientation of hetropolymeric α-helix hence proline can be placed only as 1st amino acid residue near to C-terminus 

b) proline changes the orientation of polymeric α-helix hence proline can be placed only as 1st amino acid residue near to N-terminus

c) glycine disrupts the heteropolymeric α-helix by changing the helicity.

d) homopolymer of proline and glycine can form stable helix.

Which of the following is incorrect 

a) antiparallel β sheets are frequently found and they are quite more stable because of more no. hydrogen bond presence and linear H bonding pattern.

b) antiparallel β sheets are frequently found and they are quite more stable because of more no. hydrogen bond presence and having distorted H bonding pattern.

c) parallel β sheets are relatively less stable and mostly found in core of protein.

d) parallel β sheets are relatively more stable and mostly found in core of protein.
