Intro Merge â adds variables to a dataset. Type help merge for details. Merging two datasets require that both have at least one variable in common (either string or numeric). If string make sure the categories have the same spelling (i.e. country names, etc.). The common variables must have the same name. Explore each dataset separately before merging.
Biotechnologist. Develops products with a biological ingredient or action, such as vaccines, antibiotics, hormones and washing powders. Biotechnologists are scientists who study and work with micro-organisms in a variety of areas including alcohol manufacture, agricultural genome mapping and medical science.
Biotechnology (biotech) involves the study and use of living organisms or cell processes to make useful products. The first person to produce beer by using the process of fermentation could be described as an amateur biotechnologist. Over time, the term evolved as biotechnology advanced in areas such as drug development, human and animal nutrition, agricultural improvements, and environmental protection. The cloning of insulin, used to treat diabetics, was one of the earliest modern breakthroughs in biotechnology.
