Question
Chapter 50.3, Problem 3CC
Summary Introduction
To determine: The reason that our brains receive more action potential when eyes are exposed to sunlight even though the photoreceptors release more neurotransmitter in the dark.
Concept introduction:
The human eye is composed of rod and cone cells, which helps us to see images with different color and black and white. When the light enters the eyes, the amount of neurotransmitter is decreased. Therefore the intensity of light is inversely proportional to the concentration of the neurotransmitter generated.

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.

What is the structure and function of Eukaryotic cells, including their organelles? How are Eukaryotic cells different than Prokaryotic cells, in terms of evolution which form of the cell might have came first? How do Eukaryotic cells become malignant (cancerous)?
What are the roles of DNA and proteins inside of the cell? What are the building blocks or molecular components of the DNA and proteins? How are proteins produced within the cell? What connection is there between DNA, proteins, and the cell cycle? What is the relationship between DNA, proteins, and Cancer?
