WebJul 28, 2024 · They can add genes to the body to help treat disease. Or they can turn off genes that are causing problems. To insert new genes directly into cells, scientists use a vehicle called a “vector.”... WebMutations can also be the result of the addition of a nucleotide, known as an insertion, or the removal of a base, also known as deletion. Sometimes a piece of DNA from one chromosome may get translocated to another chromosome or to another region of the same chromosome; this is known as translocation.
