38. RNA Sequencing

  • Developed By: Joe Ecker Of The Salk Institute

RNA Sequencing is one of the greatest scientific breakthroughs in history. RNA Sequencing uses high-throughput sequencing methods to provide insight into the transcriptome of a cell.  Of course, a transcriptome is simply the total of all the messenger RNA molecules expressed from the genes of a given organism.

This sequencing provides superior coverage and greater resolution of the nature involved in a transcriptome when one compares it to the previous methods. It can tell us what genes are turned on in a cell, the exact level of expression present, as well as what times they are activated and even shut off.
