The synaptic transmission or neurotransmission is a process by which neurotransmitters (signaling molecules) are released by the presynaptic neuron. Turning off the stimulus on time is also important like stimulating a postsynaptic cell. If not, the postsynaptic cell could continue to fire indefinitely, leading to changes in physiological coordination. So a molecule of a neurotransmitter binds only for 1 ms or so to its receptor, then separates from it. The two ways to stop the transmission process are stopping the neurotransmitter and removing the one which is already available. The former is achieved by cessation of signals in the presynaptic nerve fibers. The second is attained by neurotransmitter degradation, reuptake, and diffusion.

5G JA ATTC 3 3 CTIA A1G5 5 GAAT I I3 3 CTIA AA5 Fig. 5-3: The Eco restriction site (left) would be cleaved at the locations indicated by the arrows. However, a SNP in the position shown in gray (right) would prevent cleavage at this site by EcoRI One of the SNPs in B. rapa is found within the Park14 locus and can be detected by RFLP analysis. The CT polymorphism is found in the intron of the Bra013780 gene found on Chromosome 1. The Park14 allele with the "C" in the SNP has two EcoRI sites and thus is cleaved twice by EcoRI If there is a "T" in that SNP, one of the EcoRI sites is altered, so the Park14 allele with the T in the SNP has only one EcoRI site (Fig. 5-3).

From your previous experiment, you found that this enhancer activates stripe 2 of eve expression. When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?

What experiment could you do to see if the maternal gene, bicoid, is sufficient to form anterior fates?
