By which mechanism does the replication of new lambda DNA molecules are produced in the host bacterium?

Two monochromatic waves having frequencies $$\omega $$ and $$\omega + \Delta \omega \left( {\Delta \omega \ll \omega } \right)$$ and corresponding wavelengths $$\lambda $$ and $$\lambda - \Delta \lambda \left( {\Delta \lambda \ll \lambda } \right)$$ of same polarization, travelling along X-axis are superimposed on each other. The phase velocity and group velocity of the resultant wave are respectively given by

A

$$\frac{{\omega \lambda }}{{2\pi }},\,\frac{{\Delta \omega {\lambda ^2}}}{{2\pi \Delta \lambda }}$$

B

$$\omega \lambda ,\,\frac{{\Delta \omega {\lambda ^2}}}{{\Delta \lambda }}$$

C

D

$$\omega \Delta \lambda ,\,\omega \Delta \lambda $$

Consider the following statements regarding DNA replication and choose the correct answer:

C

The lysis fate is that where the phage inserts its genome into the bacterial genome and the replication goes on

D

The lysogenic fate is that where the phage infects the cell and lysis is carried out
