Sure I haven’t taken too many yet but I took general chemistry and organic chemistry on youtube.

I recommended intro to bio by mit (great intro to how biochemistry and genetics joined together to become the field of biotech as we know it today) as well as medicinal chemistry in edX.

There are more and more biology related MOOCs popping up frequently.
