a.

Summary Introduction

To explain:

The result of double-stranded RNA (dsRNA) on gene expression.

Introduction:

Gene expression is provides the information from DNA to RNA to protein, it is process in which the information of gene is used in the synthesis of a functional gene product. It involve the two stage, transcription, where the production of $\text{mRNA}$ is done by using RNA polymerase and the processing of the resulting $\text{mRNA}$ molecule. The gfp is a green fluorescent protein, it used as reporter gene in the experiment to determine the gene expression.

b.

Summary Introduction

To explain:

The Fire and Mello experiment in which they injected double-stranded RNA complementary to the introns and promoter sequences of the gfp gene.
