Chapter three was very fascinating. Injecting vitamin A into the chicken embryos it will give the mirror-image duplication. This experiment is awesome you could probably make a chicken have like four wings or something. Also, the genetic experiments done by tabin's lab to find the molecule that controlled the pinky formation from the thumb. Furthermore, the function of hedgehog-to make one region different than the other-is just like ZPA in making the pinky different from the thumb. -Emmanuel Morales
I found in this chapter that genetics is very interesting. I read that they found out the gene that makes zpa, which makes finger, is in every kind of animal even a fish.I read that if they inject vitamin A into the chicken embryos, the zpa will go on the opposite of the first zpa and make a mirror-image duplication. i thought that this is one of the first steps in the field of genetics to be very interesting.
This chapter was pretty cool. They found a gene called ZPA in chickens and found that we also have that gene. That gene makes our thumb and piky different from eachother as the gene turns on and off.
This chapter was interesting on how the vitamin turned the embryos duplicate. But the thing that got my attention was whe it talked about ZPA on how both chicken and humans have this gene.
i thought it was pretty interesting to find out that humans shared genes with other living organisms, i had been under the previous mindset that all creatures had their own dna and genes, so this was a bit of an eye opener for me J.M.DiPietro PS-Tolmans a G!!!!
I find it really interesting how our DNA is exactly the sam ein every cell in our bodies but all of our body parts are completetly different from another. Our body is reall is extremely complex and intelligent because it has the ability to give directions and make all of our genes perform a different action to form our limbs.
The experiments Shubin and his colleagues came up with to prove their hypothesis about Tiktaalik and other missing links helped me understand exactly what they were looking for. What I understood is that they were looking or a way to turn fish fins into limbs similar to a human's to see if it would be possible in nature. I didn't know that different parts of DNA could be "turned on" in a cell. Shubin is really helping me look at things in a new way. -Morgan Wininger
Chapter three helps us to see the great things that science has to offer. Experiments allow us to manipulate something to give us results. Just the way that Shubin uses and explains their use of chicken embryos. He mentions that if one thing were to go wrong that it could completely alter the embryo, and that also goes for us. Genes are really something. -Loremae Mopera
