Question
Chapter 43, Problem 9TYPSS
Summary Introduction
To review:
The reason why drugs preventing the neurotransmitters from being taken back up by a presynaptic neuron have dramatic effects on the activity of postsynaptic neurons.
Introduction:
A synaptic cleft is formed by the presynaptic and postsynaptic membranes of the neurons. The binding of the calcium ion to the synaptic vesicles triggers the release of the neurotransmitters from the presynaptic membrane into the synaptic cleft. The receptors for these neurotransmitters are present on the postsynaptic membrane.

8. Transcription and Translation Practice: (Video 10-1 and 10-2)
A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense
DNA strand and label the 5' and 3' ends.
B. Use the antisense strand that you create in part A as a template to create the mRNA
transcript of the gene and label the 5' and 3' ends.
C. Translate the mRNA you produced in part B into the polypeptide sequence making sure
to follow all the rules of translation.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas.
