Question
Chapter 1.3, Problem 2CC
Summary Introduction
To explain:
How discovery-based science helped researchers to hypothesize that the CFTR gene encodes a transporter.
Introduction:
Discovery-based science is a method of collecting and analysis of data without having a hypothesis. The usefulness of this method is the data obtained from this method may lead to a new hypothesis. So, discovery-based science eventually leads to hypothesis testing.

You got an opportunity to join a professor lab who is working in-vivo model and specifically looking at the dysregulation of mitochondria in liver. He asked you to isolate mitochondria from a Rat liver and placed in an assay medium. Based on the knowledge you gain in this course so far, please answer the following questions:
a) Which technique will you use to isolate mitochondria?
b) What happens to the pH of the medium when the medium is kept anaerobic?
c) What happens when O2-saturated saline is added to the mixture?

- Identify the single most correct answer: a) Ribosome is an organelle found in both prokaryotes and eukaryotes. Ob) During conjugation a naked DNA molecule found in the surroundings gets into bacteria. c) Spontaneous mutation cannot result in the production of an altered protein. Od) Gene transfer from one species of bacteria to another (donor to recipient) represents horizontal gene transfer.arrow_forward25) Identify the most correct choice: a) ribosomes are the membrane bound organelles responsible for making proteins from RNAs. b) In gene therapy, Agrobacterium is the bacteria that transfers genetic material into the human cells that contain the mutated gene. c) spectrophotometer analysis can be used to detect the concentration of the dead cells in a solution only and not those that are living. d) None of the above.arrow_forwardHow did the discovery of ribozymes affect our understanding of the origin of life and the RNA world? A) The discovery of ribozymes demonstrated that enzymes did not have to be proteins, and that RNA can store, transmit, and do biological work as an enzymatic molecule. B) The discovery of ribozymes helped us understand why RNA only stores and transmits biological data, but does not act as an enzymatic molecule. C) The discovery of ribozymes verified that enzymes had to be proteins. This discovery helped to eliminate other theories about the origin of life in RNA world. D) The discovery of ribozymes demonstrated definitively that ribozymes function only as an enzymatic molecule and therefore evolved before information carrier molecules.arrow_forward
