Topic: Monarch Butterfly...

I have heard that when a caterpillar changes to a Monarch butterfly it's DNA changes completely. True or False?

Re: Monarch Butterfly...

I'm no molecular biologist, but I can't conceive of this being true.  I believe that within the DNA of the creature are the instructions for the remarkable transformation of monarchs and all other insects that go through complete metamorphosis.  That the metamorphosis is completed in an essentially identical manner throughout the population from generation to generation suggests that the DNA instructions for the change are passed down without any change whatsoever.
