splice it into another organism’s genetic material. This recombination of DNA is known as recombinant-DNA.
o develop kinds, and strains, of organisms that would benefit human beings. Scientists proved that genes are made of a chemical called deoxyribonucleic acid (DNA). DNA molecules are big compared to most other molecules. DNA molecules are made up of many smaller molecules. When cell divides the DNA reproduces. The new cells are just like it was before it split. The new cells have the same genetic information that it had before it split. Even though humans have the same genes individuals may inherit different genes, which is what make each person unique. Each new organism resembles its ancestors, and yet it differs from them. Children may look like one parent or another, but usually they have some characteristics of each. Each human seems to be a mixture of traits. Some can be recognized in members of the family, while oth
