Abstract
VARIOUS genetically determined human and animal haemoglobins differ in the amino-acid sequences of their polypeptide chains1,3,6. On the basis of the ribonucleic acid triplets published recently4,5 all abnormal human haemoglobins which are due to single amino-acid substitutions can be explained by single base pair changes in the deoxyribonucleic acid. Comparing the normal human β- and δ-chains we found that only the exchange of threonine to glutamine in position 87 (1 of 10) cannot be interpreted by a single point mutation.
