Step 1: Understand the problem and identify the options
The problem asks us to identify the best description of transcription from a list of options. Transcription is a fundamental process in molecular biology, so we should be familiar with its definition and the roles of various molecules involved.
Step 2: Analyze the first option
Transcription is the replication of DNA molecules so that each cell will have the same DNA. This statement is incorrect because transcription does not involve the replication of DNA molecules. DNA replication is a separate process that creates identical copies of DNA molecules before cell division.
Final Answer
Transcription is the conversion of a DNA code into an mRNA code.
