Answer

Frederick Griffith discovered transformation in Streptococcus pneumoniae. Live non-virulent R cells became virulent after taking up material from heat-killed S cells.

Card 7Transformation

Define transformation in bacteria.

Answer

Transformation means transfer of genetic material from one cell to another that alters the genetic makeup of the recipient cell. In Griffith's experiment, R cells changed into virulent S cells.

Card 8परिवर्तन

जीवाणु में परिवर्तन की परिभाषा दीजिए।

Answer

परिवर्तन का अर्थ है एक कोशिका से दूसरी कोशिका में आनुवंशिक पदार्थ का स्थानांतरण जो प्राप्तकर्ता कोशिका की आनुवंशिक संरचना को बदल देता है। ग्रिफ़िथ के प्रयोग में आर कोशिकाएँ उग्र एस कोशिकाओं में बदल गई…
