Crash course system biology

Question 1

In a network how can you determine if the node has high or low degree and high or low betweeness

Answer 1

High degree if a node has many edges and high betweenness if the node has many shortest paths going through it

Question 2

How does a gene network module identified using the Louvain method of community detection in igraph look?

Answer 3

Gene regulatory networks and edges between the nodes show the gne regulation as the gene can inhibit or prome each other

Question 4

Draw the graph of the network based on the following adjencacy matrix:

A= 0111
1010
1101
1010

Answer 4

Draw this

Question 5

1010
1101
