1. GENE TECHNOLOGIES ARE AN AMAZING PART OF BIOLOGY, BUT ARE HUMANS GOING AGAINST WHAT GOD HAD ORIGINALLY INTENDED?
While many commonly used antibiotics interfere with protein synthesis or cell wall formation, clorobiocin, one of several antibiotics in the aminocoumarin class, inhibits the activity of bacterial DNA gyrase. Similar drugs have been tested as treatments for human cancer. How might such drugs be effective against bacteria as well as cancer?

- Genetically Modified Foods The creation of transgenic crop plants using recombinant DNA methods involves the transfer of just one gene or a small number of genes to the plants, in contrast to classical breeding methods in which hundreds or even thousands of genes are transferred at once. Explain why this is true. If fewer genes are transferred during the creation of transgenic crops, why are some people afraid that they are dangerous?arrow_forwardX-rays strike a chromosome in a living cell and ultimately cause the cell to die. Did the X-rays produce a mutation? Explain why or why not.arrow_forwardMany cancer cells are immortal and can be cultured in the laboratory for many years. Many of these cell lines have highly active telomerase activities. Why would that affect the ability of cancer cells to sustain growth and cell division?arrow_forward

Why?arrow_forwardmutation are random change to the structure of gene. the likelihood of a mutation occuring can increase if a cell is . when mutations in a gene alter the sequence of amino acids, can be alteredarrow_forwardThe Discovery of cdc2 as the key regulator of the cell cycle by Paul Nurse 3. When Paul Nurse did his own cdc screen in fission yeast, why was he more attracted to the wee mutants than to any of the other mutants? Why were smaller cells more interesting to him than arrested, or bigger celled mutants? 4. How did the Nurse lab people show that humans had a cdc homologue?arrow_forward
- EVOLUTION LINK DNA technology, such as the production of transgenic animals, is possible only because widely different organisms have essentially identical genetic systems (DNA RNA protein). What is the evolutionary significance of the universality of genetic systems in organisms as diverse as bacteria and pigs?arrow_forwardIn 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a persons own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwangs group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?arrow_forwardIn 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients.
