Hey guys,
I have a few questions, if you can help me out it would be great. First year bio by the way, so don't get too complex on me. I'm a chemistry major, so excuse my ignorance when it comes to anything biological.
During neuralation, the verterbrate nerve cord is a tube whereas in inverterbrates it is a rod. Why exactly is this?
Also, How do the cells of the dorsal blastopore lip know in which direction to go when they invaginate?
Any help would be great guys :)
