Here is your template DNA strand:
CTT TTA TAG TAG ATA CCA CAA AGG
1. Write out the complementary mRNA that matches the DNA
above.
2. Write the anticodons and the amino acid sequence.
3. Change the nucleotide in position #15 to C.
4. What type of mutation is this?
5. Repeat steps 1 & 2.
6. How has this change affected the amino acid sequence?
7. Now remove nucleotides 13 through 15.
8. Repeat steps 1 & 2.
9. What type of mutation is this?
0. Do all mutations result in a change in the amino acid
sequence?
1. Are all mutations considered bad?
2. The above sequence codes for a genetic disorder called
cystic fibrosis (CF).
3. When A is changed to G in position #15, the person does not
have CF. When T is changed to C in position #14, the
person has the disorder. How could this have originated?

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
