Depends Really...Hmm.. Hard Question.
No. That is not possible.
small change in the DNA of a single gene
nope,, his dna is still male dna because dna is unchangeable even if he change his genital. that's why dna can be used to identify an individual.
change in DNA that caused sickle cell disease
When a person with a genetic disease receives healthy DNA as treatment, it is call gene therapy. Gene therapy is still considered experimental but may have potential in preventing and treating diseases like cancer.
A mutation is a permanent change in the DNA sequence of a gene. It may be a minor or a major change; and may be harmful or beneficial.RegardsTime is imaginary
A Change in a DNA molecule is called a Mutation. This could have anything from no effect whatsoever, to causing a catastrophic disease (such as Sickle Cell Anaemia) to death.
You can't. That would make you a totally different person. Your DNA is in you forever.
DNA sequencing
because it is a disease passed on from dna
No, this is not posible, because you can't remove all the DNA in atoms in the blood or else they wouldn't have any charicteristics even if you replaced it with others the DNA would just confuse the Body.
Can't. That's a result of your DNA and until/unless you can change your DNA, you are you. You'll just get an AKA associated with your name next time you're arrested.
