Summary of DNA mutations
Flashcards on DNA mutations
(Conservative/Nonconservative) mutations are when the new amino acid that is produced via a missense mutation has similar chemical properties to the original amino acid.
Questions on DNA mutations
Genetic mutations and repair
A researcher has discovered a rare and previously unknown autoimmune disease. CD8+ T cells isolated from patients are resistant to apoptosis, and proliferate at a much higher rate than normal. Upon further study, the researcher discovers that these cells contain a mutation in a cell surface receptor. The mutation causes the receptor to become inactive. However Western blotting shows that the mutant and wild-type receptors have the same molecular weight. What type of mutation do these patients carry?
