Textbook Question
Chapter 58, Problem 3A
If a pesticide is harmless at low concentrations (such as DDT) and used properly. how can it become a threat to nontargct organisms?
a. Because after exposure to DDT. some species develop allergic reactions even at low levels of exposure
b. Because DDT molecules can combine so that their concentration increases through time
c Because the concentration of chemicals such as DDT is increasingly concentrated at higher trophic levels
d. Because global warming and exposure to UV-B radiation renders molecules such as DDT increasingly potent

Explain:
Healthy Cell Function Overview→ Briefly describe how a healthy cell usually works: metabolism (ATP production), pH balance, glycogen storage, ion transport, enzymes, etc.
Gene Mutation and Genetics Part→ Focus on the autosomal recessive mutation and explain:
How gene mutation affects the cell.
How autosomal inheritance works.
Compare the normal and mutated gene sequences simply. → Talk about possible consequences of a faulty hydrolytic enzyme.
Can you fill out those terms
Explain down bellow what happens to the cell:
Decreased pH in mitochondria
Increased ATP
Decreased pH in cytosol
Increased hydrolysis
Decreasing glycogen and triglycerides
Increased MAP kinase activity
Poor ion transport → For each one:→ What normally happens?→ What is wrong now?→ How does it mess up the cell?

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).

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.
