300
the process, ____, that promotes genetic variation when chromosomes are combined in a ___

300

beta thalassemia is a disorder caused by mutations in the HBB gene; when looking at the HBB protein in someone who has beta thalassemia scientists have found that the protein is missing amino acids at the carboxyl terminus. The best explanation for how this mutation could result in the loss of the carboxyl terminus is ____
what is...the mutation changes a codon in the coding region of the HBB transcript to a STOP codon so translation finishes too early
