Explain the role of scientist :
$1.$ Francis Crick
$2.$ Friedrich griphith $(1928)$
Francis Crick proposed the Central dogma in molecular biology,
He concluded that the $R$ strain bacteria had somehow been transformed by the heat-killed $S$ strain bacteria. Some ‘transforming principle’, transferred from the heat-killed $S$ strain, had enabled the $R$ strain to synthesise a smooth polysaccharide coat and become virulent
Who proved first time that $DNA$ is a genetic material
How it was proved that $DNA$ is the Genetic material ?
Chemically $DNA$ differs from $RNA$ in having
Which scientist experimentally proved that $DNA$ is the sole genetic material in bacteriophage ?
Give scientific reasons : Viruses can be used in the manufacturing proteins.
