<span>Are mirror images of one another
in science, an enantiomer, otherwise called an optical isomer, where you have two stereoisomers that are perfect representations of each other that are non-superimposable , much as one's left and right hands are the same aside from being turned around along one pivot.</span>
<span>The chromosomes of two diploid cells split apart at the centromere</span>
Answer:
DNA technology and gene cloning are essential to the pharmaceutical industry and medicine. DNA technology is being used to help diagnose genetic diseases, such as sickle-cell disease and Huntington's disease.
<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.
