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 α type and two subunits of β type.) In the light of the above statements, choose the correct answer from the options given below:
A) Statement I is false but Statement II is true.
B) Both Statement I and Statement II are true.
C) Both Statement I and Statement II are false.
D) Statement I is true but Statement II is false.
