7.81J Systems Biology

7.81J Systems Biology (Fall 2014, MIT OCW). Instructor: Professor Jeff Gore. This course provides an introduction to cellular and population-level systems biology with an emphasis on synthetic biology, modeling of genetic networks, cell-cell interactions, and evolutionary dynamics. Cellular systems include genetic switches and oscillators, network motifs, genetic network evolution, and cellular decision-making. Population-level systems include models of pattern formation, cell-cell communication, and evolutionary systems biology. (from ocw.mit.edu)

Lecture 06 - Graph Properties of Transcription Networks

In this lecture, Prof. Jeff Gore finishes the discussion of oscillators. This includes alternative designs for oscillators, including positive and negative feedback. He then discusses one of the most cited scientific articles: Emergence of scaling in random networks, by Barabasi & Albert. The lecture ends with the topic network motifs.
