Question

In the pneumococci experiment, what was the initial form of the bacteria before treatment?

विकल्प

• Smooth, non-type-specific pneumococci

• Rough, non-type-specific pneumococci

• Rough, type-specific pneumococci

• Smooth, type-specific pneumococci

Answer 1

The experiment began with rough, non-type-specific forms of type III pneumococci. These were then exposed to extracts of dead smooth type III pneumococci, leading to their conversion into smooth type III pneumococci.
