Biotechnologists are scientists who study and work with micro-organisms in a variety of areas including alcohol manufacture, agricultural genome mapping and medical science.
Biotechology is where crops lacking any varieties with any of the micronutrient of interest, can be candidates for utilizing genes from other plants, such as beta-carotene, and inserting that trait of interest into a staple crop using techniques of genetic modification.
