Griffiths (1928) mixed heat-killed 'S' bacteria with 'R' bacteria and injected a mouse with both types of bacteria. As a result, the mouse died and Griffiths obtained living 'S' bacteria from the dead mouse. How can you explain this phenomenon? The DNA from the 'S' bacteria with the gene responsible for capsule formation was transferred to the 'R' bacteria when the strains were mixed. This gene transformed the 'R' bacteria into 'S' bacteria, allowing it to produce a capsule and eva...

MMSC407 Final Exam Questions with Correct Answers Describe the characteristics of light as an energy source. - Answer-1. Wavelength - the distance between the crests of two successive waves 2. Amplitude - the height of each wave 3. Frequency - the number of waves which pass an observation point in one second In terms of energy: -High energy = high frequency, short wavelength -Low energy = low frequency, long wavelength Describe the relationship between percent transmittance and absorb...
