Someone asked about genome sizes ... from my intro genetics notes:
DNA length / cell est. no of genes
Lambda phage 17 microns 50-60
T4 phage 70 200
E Coli 1 000 3000
Drosophila 1 600 approx 50 000
Homo Sapiens 1.74 metres apporx 200 000
BUT!
Necturus ('mud puppy') has 17.5 times longer DNA / cell than homo sapiens,
trilliums have 18.5 times more, and Amphiuma ('congo eel') have 26 times
more (approx 130 feet)
so usually, it gets bigger as you go up the evolutionary ladder, but not
always.
