Lecture 3.3 Transcription

Overview

The first step in the central dogma has information flowing from DNA to RNA. That process is called translation. Conceptually, as we saw in the previous lecture, the information coded in the sequences of bases on DNA must be accurately copied into a sequence of bases on RNA. The product is called messenger RNA, or mRNA. In this lecture we begin a study of the details of the mechanisms the cell uses to accomplish this task.
