Question
Chapter 19.2, Problem 3CC
Summary Introduction
To propose a hypothesis: To compare viral and cellular RNA polymerase in terms of template and functions.
Concept introduction: Cellular RNA polymerase is an enzyme found in all organisms. Viral RNA polymerases play an important role in replication and transcription of virus. Replication is a process of synthesizing an exact copy from the parent or template strand. Transcription is a process where RNA is formed using DNA or RNA as a template.
