When a cell copies its dna (replication), the original dna indder is broken apart and new mucleotides are
added to the center. this creates two exact copies, each one made from half the original dna molecule
dna polymerase (the enzyme which buikis dna) will only attach beses which match with the
original strand of dna
in dna replication, adenine and thymine will bong together and cytosine and guanine will
bond together.
when creating the matching stand the following pairing mles must be used
a? t
c? g
directions. use the base pairing rules above to figure out the sequence of the new strand of dna for the
original strands below.

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.
