The correct order of the given phases of action potential is: Resting potential, Depolarization, Repolarization and Resting conditions.
Action potential is a series of events where the membrane voltage of the nerve cell observes fluctuations in order to transmit an electrical signal. These fluctuations are very rapid and occur due to the influx and efflux of certain ions through the membrane.
Depolarization is the state of action potential where the sodium ion channels open upon receiving some stimulus. The sodium ions therefore move inside the cell and change the membrane voltage from negative to positive. The membrane voltage initially at -70 mV hits the threshold at -55 mV.
The given question is incomplete, the complete question is:

According to the operon model, for the synthesis of an inducible enzyme to occur, the:
A. end-product must not be in excess.
B. substrate must bind to the repressor.
C. repressor must not be synthesized.
D. repressor must bind to the operator.
E. substrate must bind to the enzyme.
According to the operon model, for the synthesis of an inducible enzyme to occur, the: B. substrate must bind to the repressor.
An operon is a functional piece of DNA in genetics that houses a collection of genes that are all regulated by the same promoter. The genes are combined during transcription to form an mRNA strand, which is then either translated in the cytoplasm as a single unit or split up during splicing to form monocistronic mRNAs, which are translated separately and consist of multiple strands of mRNA that each encode a single gene product. The operon's genes as a result either express themselves simultaneously or not at all. An operon is defined by the co-transcription of many genes.
From the discovery of the first operons in eukaryotes in the early 1900s, operons have been assumed to exist only in prokaryotes (which includes organelles like plastids that are derived from bacteria).
