2. Genetically modified crops are foods that have had specific changes introduced into their DNA. Using genetic engineering, scientists can take genes that control a trait from one organism and insert the genes into another organism's genetic code. This process creates an organism with the desired characteristics.
Which statement describes how scientists are able to use genes from one organism on another?
A. Similarities in the physical characteristics of organisms are due to common ancestors.
B. Organisms that are closely related have identical genetic information.
C. The basic components of DNA are universal in all organisms.
D. Different species exchange DNA during reproduction.
