The HD Gene: Under the microscope
The HD Gene: Under the microscope

... DNA. DNA is the name of the chemical that our genes are made from. The letters ‘DNA’ stand for Deoxyribonucleic Acid (catchy, isn’t it?). Not surprisingly, nobody really uses the full name DNA is a lot easier to say and remember. DNA is what we inherit from our parents, and they inherited theirs fro ...

... Asp-147, the two mutations at Asp-163, and the Arg substitution for His-141. On the other hand, the change of His-141 to Ala or Pro abolished all protease activity in this system; the full-length translated p137 accumulated, and no capsid protein was detectable. The changes introduced at Ser-215 res ...

... From amino acid analysis, one can predict the number of cleavage fragments that one should get. For example, if the protein contains 5 arginine and 7 lysine residues, there should be 12 cleavage points, and 13 peptides produced. Methionine is a relatively rare amino acid, so the cyanogen bromide cle ...

Point mutation



A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
