This bacterial cell can now be used to produce
1. the bacterial gene for insulin that can be inserted into humans
2. human genes for enzymes that can be inserted into humans
3. insulin that can be used by humans
4. enzymes necessary to treat human diseases

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.

Which phase of the cell cycle ensures that identical copies of the dna are made for daughter cells?

The hematodinium parasite becomes less of a problem for the blue crab when the crab is very young. fishing is thriving in the region. the crab moves to less salty water. a significant percentage of the population is impacted.
