Lecture 3.4: Translation Overview The second step in the central dogma has information flowing from RNA to protein. That process is called transcription. Conceptually the information coded in the sequences of bases on RNA informs the cell of the proper … Continue reading →

Lecture 3.3: Basic Gene Function Overview What does DNA and its genes, whatever those are, actually code for? This question is also still evolving. At one point in time, around the 1980s, we were fairly certain that we knew the … Continue reading →

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 … Continue reading →

Lecture 3.2: Gene Structure and Arrangement Overview The molecular structure of DNA provided clues to its replication, as we saw in the previous lecture. It was also fairly obvious that the information held in the DNA was somehow coded in … Continue reading →

Lecture 3.1: DNA Structure and Replication Overview One of the most fascinating aspects of DNA is that some of its function becomes obvious once its structure is known. The elucidation of its structure–a double helix with strict base pairing rules–took … Continue reading →
