Summary Introduction
To write:
About the cGMP levels greatest in photoreceptors- when they are exposed to light or when they are exposed to dark and the effects cGMP has on sodium channels in the external/outer segment of the photoreceptors.
Introduction:
Retina- situated the backside of the eye is made up of photoreceptive cells known as the Rods and Cones. It is responsible for the transduction of light into nervous impulses. Rods contain a chromophore 11-cis retinal which is attached to the cell membrane protein, opsin.
G-proteins act as mediators of cell signaling pathways and require signaling molecules which are called the second messengers. Cyclic-GMP is a G-protein signaling cascade in photo transduction.
There is a biological change of a photon into an electrical signal in the retina. This process is carried out by the G-protein coupled receptors called opsins. The photons are absorbed by the rhodopsin and converted into

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud.
What is the phenotype of the resulting ectopic limb?
Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
