Researchers performed an experiment to investigate dna replication. first, they synthesized radioactively-labeled nucleotides, which are nucleotides that contain radioactive elements that allow them to be visualized. then, they inserted the radioactively-labeled nucleotides into a cell. when the cell divided, it incorporated the radioactively-labeled nucleotides into its dna during dna replication. the following image shows the cell's dna before and after replication. the original dna strands are shown in blue and the dna strands with the radioactively-labeled nucleotides are shown in orange. which statement is best supported by the results of this experiment? a. cell division produces four identical dna strands. b. several proteins are involved in dna replication. c. dna replication is a semiconservative process. d. the two dna strands are replicated in opposite directions.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
