Hello Biostars,

What are an approximate quantity of human genes, transcripts (coding transcripts), proteins and metabolites? What about a model plant like Arabidopsis?

Thanks
Here are some statistics that I found in different databases:

For human:

 - Coding genes: about 20,441
 - Non-coding genes: about 22,219
 - Transcription factors: about 2,067 (TFs/total genes= 10 %)
 - Transcripts: about 198,002 (Transcripts/genes = 9.68)
 - Proteins: more than 30,057
 - Metabolites: more than 42162

Any revision or adding more information to this post would be
   appreciated,
