Bits of DNA (in green) protrude from the chassis like little feet. The motor is fueled by RNA laid on a track. The RNA binds with the DNA feet on the bottom face of the chassis. An enzyme ...

Learn more about the DNA transcription process, where DNA is converted to RNA, a more portable set of instructions for the cell. The process of transcription can be visualized by electron ...

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins. In reality, there is much more to the RNA story. However ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...
