The zebra danios are a new type of pet fish, marketed as Glo-Fish. The fish were produced by transferring genes from jellyfish (green and yellow fish) and corals (red fish) into regular zebra danio fish (striped blue and white normally) embryos. Which of the following statements is true about these fish? These fish have recombinant DNA They have been selectively bred. They are now photosynthetic This happens naturally in the wild.

Some antibiotics inhibit protein synthesis in bacteria, but do not affect synthesis of human proteins that are encoded by nuclear genes. Other reagents inhibit synthesis of proteins that are encoded by human nuclear genes but not of bacterial genes. How could you use these compounds to test which proteins are encoded by the mitochondrial genome? Expalin

Which of the following human cells have the least genomic DNA, as measured by the total number of base pairs found in the cell? a neuron that is not dividing a cell that has just entered meiosis I a sperm cell

Suppose you have been directed to find new enzymes to use in the breakdown of wood in order to process biofuel (switchgrass, for example). Suppose you wanted to use fungal or bacterial DNA from the environment in order to do so. DNA can be unwound from the double stranded double helix into single strands, amplified, separated on gels by size, stained with dyes. It can be mutated by a variety of means. It can be sequenced. Describe one or more of the ways that you might manipulate DNA towards the stated goal. Relate the technology you plan to utilize to the structure of DNA. (You can break this into multiple posts, as multiple procedures might be used).
