Answer:
They can pass through the semi permeable membrane
Explanation:
The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through
If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.
Hmm let’s see...I think this might answer you question ——
<span>1.
</span>They act as activators of transcription. This is
through increasing the affinity of the RNA polymerase on the promoter
<span>2.
</span>They could act as repressors. This way, when
they bind to their active sites, they
repress the binding of the RNA polymerase on the promoter
<span>3.
</span> Transcription factors at one site could affect transcription of genes on another site on the
DNA. The flexibility of the DNA (by forming loops) allows for this phenomenon.
