Chapter 26, Problem 21E
Summary Introduction
To explain: How the inhibition of snRNA processing after the infection with the viruses favors the expression of the viral genes in the host cell.
Introduction: In eukaryotes, transcription occurs in the nucleus and pre-mRNA is synthesized. This pre-mRNA is further modified before the translation in cytoplasm. This is known as RNA processing and splicing. Small nuclear RNAs (snRNAs) are
