6. Read interesting facts about cloning, discuss them and find your own. Did you know…?

• Dolly the cloned sheep was named after country singer Dolly Parton, because she started life as a mammary cell.

• We leave our DNA around all the time, everywhere: on the door, on the table, on the keyboard…For the moment we couldn’t clone from it, but hey, perhaps later we may be able to clone you from the tiny bits of DNA you leave about!

• Humans have far fewer genes than expected at 35,000 to 42,000, compared to the nematode worm with 18,000 and the fruit fly with 13,000. However, scientists say we may still have more – we don’t know the whole genome set yet and we may have missed some genes.

• The difference between humans and fruit flies or worms is that human genes work differently, are capable of multitasking, and we have more control genes.

• Most mutations occur in males.

• In each of our cells, there are six feet of DNA packed into a chromosome only 0.0004 inches across.

• Lining up all of the DNA in the human body, it would reach to the sun and back more than 600 times.

• Our DNA is 99.9% identical to all other members of the human race.
