Short Answer TypeWhat do you mean understand by tertiary structure of proteins? Mention the forces involved informing these structures.
Tertiary structure of proteins : When the polypeptide chain with its secondary structure is further folded and twisted about itself a tertiary structure is formed. The tertiary structure of a protein adopts coiled compact structure of varying size and shape. The various forces involved in forming tertiary structures are,
(i) Hydrogen bonding.
(ii) Disulphide bridge.
(iii) Ionic or salt bridge.
(iv) Hydrophobic interaction.
Long Answer TypeName the product obtained on complete hydrolysis of DNA. Enumerate the structural differences between DNA and RNA. In what way is a nucleotide different from a nucleoside? Illustrate with examples.
Short Answer TypeThe tertiary structure of many proteins dissolved in water is disrupted by heating above 80°C, but primary structure is unaffected. Explain.
