If the lac repressor were altered so it could not release lactose once lactose was bound to it then you would predict that " the repressor could not bind to DNA".
<u>Option:</u> A
<u>Explanation:</u>
A DNA-binding proteins prevent gene expression coding for proteins engaged in bacterial lactose metabolism is understood as the lac repressor.
Such genes are repressed if lactose is not accessible to the cell, meaning that when lactose is available, the bacterium only spends energy in the development of machinery required for the absorption and processing of lactose.
When lactose is accessible, it is transformed into allolactose, which prevents the DNA binding ability of the lac repressor and thus increases the gene expression.
Explanation:
Molecular biology is a branch of biology that concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, proteins and their biosynthesis, as well as the regulation of these interactions.
Answer:
Yes, it is a balanced equation.
Explanation:
H2O -> H2 + O2
Answer:
motor neurons
Explanation:
muscles contraction begins when the nervous system generates a signal.The signal, an impulse called action potential, travels through a type of nerve cell called motor neuron. The neuromuscular junction is the place where the motor neuron reaches a muscle cell.
