Answer
  • True
  • False

Question 4

Question
The primary structure of Haemoglobin is the [blank_start]sequence of amino acids[blank_end]. The secondary structure is when it folds to [blank_start]form an alpha helix[blank_end]. The tertiary structure is when it folds even more. The quaternary structure is when there is [blank_start]more than one polypeptide chain[blank_end]. The iron is a [blank_start]prosthetic group[blank_end] to the protien.
