What would happen to the transcription process

if a drug added to a eukaryotic cell inhibited the

phosphatase?

Interpretation Introduction

Interpretation:

The change that would happen to the transcription process if a drug added to a eukaryotic cell inhibited the phosphatase is to be stated.

Concept Introduction:

A biological process in which the information present in DNA is copied to RNA (mRNA) is known as transcription. The initiation of transcription takes place in the presence of RNA polymerase. The three types of RNA polymerase are Pol I, Pol II and Pol III. Pol II is used for the formation of mRNA.

Explanation of Solution

A biological process in which the information present in DNA is copied to RNA (mRNA) is known as transcription. The initiation of transcription takes place in the presence of RNA polymerase. The three types of RNA polymerase are Pol I, Pol II and Pol III. Pol II is used for the formation of mRNA.

At initial step, Pol II is present in unphosphorylated form. The elongation of RNA takes place by phosphorylation of unphosphorylated form of enzyme...
