The correct option is D.<span>
Craig Venter contributed significantly to
science and humanity by inventing a synthetic cell. He accomplished this by
constructing the genome of a bacterium and by incorporating it into a
cell. The cell was made by joining together the genome of a pathogen from small stretches of DNA that are synthesized in the laboratory. The genome created was then inserted into an empty cytoplasm of a related bacterium. The pathogen use is called mycoplasma mycoides, it usually infect goats.</span>The cell is the first synthetic life form in the world and it open the
way for new types of research.
Answer:
The answer to this question is B
Answer:
A differential medium
Explanation:
Bacteria require nutrients for growth, and in order to culture (grow) them and study their characteristics, different types of media are used.
A selective media is used to grow a particular group of organism while suppressing another. So a selective media usually has an inhibitory agent, which will inhibit the growth of the undesired group. An antibiotic can be added to a medium to make it selective.
A general purpose medium as the name implies can be used to grow any group of bacteria. It has no inhibitory agent and indicator that differentiates between organisms. An example of general purpose media is nutrient agar
.
A non-synthetic media is made from natural ingredients.
A differential media differentiates between groups of organisms. Example of differential media is MacConkey agar and Mannitol Salt agar. On MacConkey agar, lactose fermenting bacteria turn pink while non-lactose fermenting bacteria are colorless.
On Mannitol Salt agar, mannitol fermenting bacteria turn yellow while non-mannitol fermenting bacteria are colorless. Mannitol Salt agar is also a selective medium. It has a high salt concentration which inhibits certain organisms.
