Facts about Cloning
the cloned sheep was named after country singer Dolly Parton, because she
started life as a mammary cell.
leave our DNA around all the time, everywhere: on the door, on the table, on the
keyboard¡K 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!
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 ¡V we don¡¦t know the
whole genome set yet and we may have missed some genes.
difference between humans and fruit flies or worms is that human genes work
differently, are capable of multitasking, and we have more control genes.
mutations occur in males.
each of our cells, there are six
feet of DNA packed into a chromosome only 0.0004 inches across.
up all of the DNA in the human body, it would reach to the sun and back more
than 600 times.
information would fill 200 500-page telephone directories.
Our DNA is 99.9% identical to all other members of the human race.
