2. The true statement about 3D structure of protein:
A. The 3D structure is determined by sequence of
amino acid
B. The 3D structure has non-covalent bonds
C. The 3D structure only interact with hydrophobic
interaction
D. The 3D structure is not found in human
E. The 3D structure is only important in enzyme
molecule

Jawab : A. Di Slide lecture disebutkan the primary structure is the covalent ”backbone” of the polypeptide formed by the specific sequence. This sequence is code for by DNA and determines the final three dimensional from adopted by the protein in its native state.

3. Which statement is associated with three dimensional
structure?

B. secondary structure
C. tertiary structure
D. primary.secondary,tertiary structure
E. not depending in structure of protein

Jawab : Gak tau... Maaf!!!
