Consult the genetic code to answer the following questions:
Consult the genetic code to answer the following questions:
a. What is the sequence of amino acids that this mRNA encodes?
b. What is the sequence if a point mutation changes the tenth base from a “C” to an “A”?
c. What is the effect of a point mutation that changes the fifteenth base from a “U” to an “A”?
d. How does the encoded amino acid sequence change if a “C” is inserted between the fourth and the fifth base?
e. Which would be more devastating to the encoded amino acid sequence, insertion of three bases in a raw, or insertion of two bases in a row?
b. What is the sequence if a point mutation changes the tenth base from a “C” to an “A”?
c. What is the effect of a point mutation that changes the fifteenth base from a “U” to an “A”?

2. The Finnish population has a 1 percent carrier frequency for a seizure disorder called myoclonus epilepsy (MIM 607876). Two people who have no relatives with the illness ask a genetic counselor to calculate the risk that they will conceive an affected child, based on their belonging to this population group? What is their worst possible risk?
3. Explains the connection between cancer and control of the cell cycle.
4. Define the concept of “Central Dogma” in biology, and the concepts of transcription, translation, codon, and the redundancy nature of codons in gene expression? Draw a diagram showing how gene works. (4 points)
