In Operon concept, the regulator gene regulates chemical reactions in the cell by
Inactivating enzymes in the reaction
Inhibiting transcription of $mRNA$
Inhibiting migration of $mRNA$ into cytoplasm
Inhibiting the substrate in the reaction
E.coli cells with a mutated $Z$ gene of the lac operon cannot grow in medium containing only lactose as the source energy because
In lac operon system lac gene -$I $ codes for
A low level of expression of lac operon occurs at all the time. Can you explain the logic behind this phenomena.
The processes by which $mRNA$ is made by $DNA$ and protein by $mRNA$ are respectively called as
The genes are responsible for growth and differentiation in an organism through regulation of
