1. the book opens with quotes from linnaeus and chargaff. look them up and list three achievements these two people are each famous for?

1. which two scientists are mentioned in the introduction as having discovered the structure of dna? why is dna important to genetic research?

1. in the introduction, ingen files for chapter 11 protection with the us bankruptcy courts. look up this term and explain what this means for the company in simple terms.

Explanation:

Question 1

• Carolus Linnaeus:
• Developed the binomial nomenclature (scientific naming system) for organisms, e.g., Homo sapiens for humans.
• Created the hierarchical classification system (kingdom, phylum, class, order, family, genus, species) to organize living things.
• Published "Systema Naturae" which was a foundational work in taxonomy.
• Erwin Chargaff:
• Discovered Chargaff's rules: in DNA, the amount of adenine (A) equals thymine (T), and guanine (G) equals cytosine (C) (A=T, G=C).
• His work was crucial for the later discovery of the DNA double - helix structure.
• Conducted research on nucleic acids, helping to establish the chemical basis of DNA.

• The two scientists who discovered the structure of DNA are James Watson and Francis Crick (with contributions from Rosalind Franklin's X - ray crystallography data).
• DNA is important to genetic research because:
• It is the molecule that carries genetic information. Genes (segments of DNA) code for proteins, which determine an organism's traits.
• It allows for the study of inheritance patterns, as genetic information is passed from parent to offspring via DNA.
• Understanding DNA structure and function helps in studying genetic disorders, developing gene therapies, and understanding evolutionary relationships.

• "Chapter 11 protection" in US bankruptcy courts is a form of bankruptcy reorganization.
• For a company like InGen, filing for Chapter 11 means:
• The company is not liquidated (sold off completely). Instead, it gets to restructure its debts and business operations.
• It can continue to operate while developing a plan to repay creditors over time, often with more favorable terms.
• It provides the company with a legal framework to stay in business and try to become financially viable again.

Answer:

• Linnaeus: 1. Binomial nomenclature. 2. Hierarchical classification system. 3. "Systema Naturae" publication.
• Chargaff: 1. Chargaff's rules (A=T, G=C). 2. Key for DNA structure discovery. 3. Nucleic acid research.
