Is it possible to create gene enrichment plot for wild type (only one type of sample)

Question

[khq5801]

I have identified GO terms for gene products along with the number of times that gene products occurred in my wild-type sample. For example

[Cellular Component],    GO:0005743    mitochondrial inner membrane    2

Can I create a bar plot and show the gene product against the number of times that gene products occurred in the sample?

What would the null hypothesis be in your case to test against?

[khq5801]

To show gene enrichment analysis there should be at least 2 types of samples.
