Analysis of Biological Networks (BE.440)

Lecture Notes

LEC # TOPICS
1

Course Introduction

Model networks involved in signaling - Signals that start outside of the cell (role of the ECM) and trigger cascades inside the cell, ultimately affecting gene expression

2

Information flow in the reverse direction - from DNA to RNA to protein (the central dogma)

Review of regulatory circuits and introduction to the concept of evolutionary genomics (PDF)

Key Issues: DNA replication and repair errors lead to mutations. Loss of mismatch repair leads to a hyper-Rec phenotype, which facilitates horizontal gene transfer (antibiotic resistance, etc.)
