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.
The answer is Vacuoles. After water enters this cell through the osmosis, it expands to absorb water and contract to release it.
A lactobacillus (just from the name) suggests that it's a bacterium cell.
It's a bacterium cell that's found in lactic acid in humans.
Answer:
The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can be done by digestive enzymes, hydrochloric acid. Mechanical digestion in the stomach results in the formation of bolus.
