Transcriptional regulation involve interactions between proteins and regulatory sequences (DNA). The two types of regulation are Negative Control and Positive Control. What types of statements regarding these two types of control is correct?

Explanation:

Operons are the structural unit of gene organisation

If product of regulatory gene binds to the upstream of promoter and induce expression of operon genes, system is called positively controlled whereas if product of regulatory gene binds to the operator and prevents expression of operon genes, system is called negatively controlled

An inducer binds to the repressor and induce conformational changes causing dissociation of repressor from operator therefore in absence of repressor RNA Polymerase binds to the promoter and starts transcription of genes

In some cases, A co-repressor binds to the repressor and activate it as a result activated repressor binds to the operator and prevent binding of RNA Polymerase thus blocks transcription of structural genes

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
