Given below are two statements:Statement I: A protein is imagined as a line, the left end represented by first amino acid (C-terminal) and the right end represented by last amino acid (N-terminal).Statement II: Adult human haemoglobin, consists of 4 subunits (two subunits of type and two subunits of type).In the light of the above statements, choose the correct answer:

  1. A
    Both Statement I and Statement II are true
  2. B
    Both statement I and Statement II are false
  3. C
    Statement I is correct but Statement II is false
  4. D
    Statement I is incorrect but Statement II is true

Solution & Step-by-step Explanation

1. Statement I is incorrect: By convention, the first amino acid is the N-terminal (amino end) and the last amino acid is the C-terminal (carboxyl end). The statement swaps these.2. Statement II is true: Human haemoglobin is a quaternary protein composed of two -chains and two -chains.
