Explanation / Answer

Answer 1)

FALSE statement is DNA denaturation is a cooperative process.

REASON:

DNA denaturation is a reversible process, because high temperaeture like 950C causes the separation of two strands of DNA but at annealing temperarature, these strands can re anneal with each other.

Phosphodiester bonds are cleaves and ofcourse nucleotide sequence matters because high GC content causes the melting temperature to rise and due to triple bonds, more energy is required to cleave the bond as compared to A-T bond which have double bonds.

Thus stating all other optios true, The aove mentioned statement is False.

Answer 2)

All the above mentioned statements are true regarding integral membrane proteins.
