b
The insertion of 3 bases, such as a thymine, a guanine, and an adenine nucleotide in that order at the start of a gene
c
The substitution of a thymine nucleotide with a cytosine nucleotide near the beginning of a gene
d
The deletion of a single adenine nucleotide in the middle of a gene

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.
