WebThe case for junk DNA was summarized in a lengthy paper by David Comings in 1972 where he listed four reasons for proposing junk DNA: (1) some organisms have a lot more DNA than they seem to require (C-value Parodox), (2) current estimates of the number of genes (in 1972) are much less than the number that can be accommodated, (3) the mutation …
