LIFE SCIENCE

Detailed explanation-1: -Gene therapy is a technique that modifies a person’s genes to treat or cure disease. Gene therapies can work by several mechanisms: Replacing a disease-causing gene with a healthy copy of the gene.

Detailed explanation-2: -For this task, the genetic engineer uses a restriction enzyme. These enzymes recognize specific nucleotide sequences and cut the DNA at precisely those points. It is these enzymes that allow researchers to snip a gene out of the DNA sequence from one organism and splice it into the DNA of another.

Detailed explanation-3: -To insert new genes directly into cells, scientists use a vehicle called a “vector.” Vectors are genetically engineered to deliver the necessary genes for treating the disease. Vectors need to be able to efficiently deliver genetic material into cells, and there are different kinds of vectors.
