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?
