What can you do to possibly retrieve the gold-making gene from the dead Golden bacteria?
You discover a bacteria species in a deep ocean sample that can turn olive oil into pure gold. The bacteria do not replicate well at sea level, and one night all of your "Golden" bacteria die. A. Transform a live bacterial strain with the Golden bacteria's DNA. B. Transduce a live bacterial strain with the Golden bacteria's DNA. C. Conjugate a live bacterial strain with the Golden bacteria. D. Transduce the Golden bacteria and then infect a live strain of bacteria with the transducing virus. E. There is nothing you can do because the cells are dead. You will have to search the ocean and hope to find the elusive bacteria again.
Metagenomics may be useful because
A) it could be used to detect or predict human diseases. B) it will allow for the sequencing of entire bacterial species genomes. C) metagenomes do not change rapidly. D) metagenomes are not responsive to environmental changes.
There is an autosomal gene that controls baldness, and its expression is sex-influenced. The gene for
baldness (B) is dominant in males but recessive in females. In females, the allele B1 for nonbaldness is dominant over the gene for baldness. If heterozygous, nonbald woman marries a nonbald man, what will be the appearance of their children? Work out the possibilities for each sex. What will be an ideal response?
