The order of bases in DNA that codes for the first eight amino acids in the $\beta$-polypeptide of adult haemoglobin is: CAC GTG GAC TGA GGA CTC CTC TTC In haemoglobin C, which is a cause of haemolytic anaemia, this changes to: CAC GTG GAC TGA GGA TTC CTC TTC A table lists some of the DNA triplets that code for amino acids. What change takes place in the amino acid sequence of normal haemoglobin to produce haemoglobin C?
- AGlutamic acid is changed to lysine.
- BHistidine is changed to leucine.
- CLeucine is changed to lysine.
- DProline is changed to threonine.
