Bio Exam 3 Questions and Answers 100% Pass What did Griffith discover in his experiment involving bacteria with capsule (S) and non-capsule (R) strains, and what molecule did Avery, MacLeod, and McCarty identify as responsible for this phenomenon? Griffith observed that DNA could transform bacteria, demonstrating for the first time that genetic material can be transferred through a process called transformation. The S-strain, with a polysaccharide capsule, is protected from the immune...

The model of DNA structure proposed by Watson & Crick after analysis of Rosalind Franklin's X-ray crystallography data stated that DNA is: Correct Answer-a double stranded helix DNA polymerase requires a template but not a primer to synthesize a new strand of DNA. Correct Answer-False Watson & Crick and Franklin also proposed (and we know now that this is true) that the backbone of the DNA molecule is composed of: Correct Answer-sugar + phosphate Type the letter of the strand that repr...

Exam 3: BIO1201/ BIO 1201 (Latest 2024/ 2025 Update) | Questions and Verified Answers| 100% Correct| Grade A – LSU Q: How are genes coordinately controlled in eukaryotic cells? Coordinately controlled genes in eukaryotic cells share a set of control elements. Coordinately controlled genes in eukaryotic cells are activated by the same chemical signals. Coordinately controlled genes in eukaryotic cells are located together on the same chromosome. Answer: Coordinately controlled...
