Traditionally classification has been based largely on physical appearance (structure).
New methods are using biochemical methods to compare organisms.
Eg comparing proteins, or DNA
Cross out incorrect answers:
Proteins are made up of sequences of: amino acids / sugars / nucleic acids
DNA is made up of sequences of: amino acids / sugars / nucleic acids
The  chain of haemoglobin (blood protein) consists of 146 amino acids.
The sequence of amino acids in the haemoglobin of various vertebrates has been
determined.
Some results are shown in the table below:
