Question

In Griffith's experiments with Streptococcus pneumoniae, rough non encapsulated streptococci were converted into smooth encapsulated streptococci in the presence of the heat-killed smooth encapsulated streptococci. Which microbial process had Griffith identified?

Answer 1

Answer is transformation.

Step-by-step explanation:

Transformation is known to be a gene transfer horizontally by which foreign genetic materials are being taken up from the environment. It can also be described as a process of introducing genetic material into a bacterial cell.

Note that, encapsulated bacteria are the bacteria that are surrounded or enveloped by polysaccharide capsule. The capsule enhances the ability of bacteria to be pathogenic.
