  4. Radhika - thanks for sharing the article about King Tut! Scientists now know how he died AND who his ancestors were. It's amazing how much information can be extracted from 3,300 year old DNA. It's too bad malaria medication had not been invented yet!

  5. Hi Leslie!
    I hope you are enjoying the break!
    This video was so helpful! Especially the diagrams with all of the colors! This made heredity so clear to me. I can honestly say I wasn't getting this, but i feel SO much better about it now!
    Thanks!

  6. WOW, that's amazing what they found out about the death of King Tut. I can't believe scientists can now find out so much information by just looking at DNA.

  8. This is a very good refresher but there were some things wrong.First of all it said on What Is a Protein that - Proteins are the machines that make all LIVING THINGS function from VIRUSES to... - Viruses are not living things! And after this it shows the guy dropping a ball on his foot stating that he is in pain. They say that nerves send the message (for a reflex arc) from the TOE to the BRAIN. It's supposed to go from the TOE to the SPINE since it is a reflex arc.
