According to the animation, the repressor
binds on the operator DNA strand.
To add, in genetics<span>, an operator is a segment
of </span>DNA to which a transcription factor binds to regulate gene
expression<span> by repressing it. The protein which does this is called
the repressor to prevent transcription, they bind to operators.</span>
Answer:
False
Explanation:
Supersatured solutions can be created by heating the liquid to it's boling temperature. When the solvent gets hot, the molecules have more space to move around, and there is more space for solute molecules between them. You can keep stirring in any solute, and it will continue to dissolve, even though the saturation point has been reached.
Passive transport has 3 concepts to it.. these include: diffusion, facilitated diffusion and osmosis. All 3 of these are when a solution goes from an area of high concentration to an area of low concentration. All three of these are how substances move in and out of cells. Active transport refers to a substance going from an area of low concentration to an area of high concentration. The three of these include: plasma membrane in relation to calcium and potassium, endocytosis, and extocytosis. The function of these three is to also bring substances from an area of high concentration to an area of low concentration. Membrane pumps do this by bringing the high concentration to inside the cell so the potassium and calcium switch spots. With endocytosis and extocytosis, endocytosis brings items into the cell by digesting (phagocytosis) and drinking them (pinocytosis); extocytosis almost pushes away the cell and that’s how it gets across the membrane
