The DNA in humans nongametic cells contains 6 billions base pairs. it is estimate that about 10,000 DNA changes occurs in the cell in one day. there are quickly repaired so that only a few (1 to 5) mutations accumulate in one cell in a year.;a) what percentage of the base pairs are altered each day?;b) If a cell can withstand up to 0.0001% alteration of DNA on any given day how many base pairs can be altered?;c)what percentage of DNA changes that occur in one cell in one year escape the proof reading and repair process?
