It is not necessary to do the math.
Take this first sequence of letters:
« V(D)J recombination doesn’t produce high FI for most of the genetic information necessary for implementing the function preexist in the stem cells that develop into B cell »
Now take this second sequence of letter:
« V(D)J reco/dejpecbfsjeetrxyd/mbination doesn’t pro/ctifhkeswbudhg/duce high FI/tufdhkerttpbcdgezkmds/for most of the genet/pmhezybcvfdjufpaaxd/ic information necess/apchfsjudftepmbdqa/ary for implementing the function/qgfuotyudgjdepnvxwhj/ preexist in the stem cells that/arvfhjdtupmdfzqo/ develop into B cell ».
Can you see that the functional information in the first sequence is already nearly there in the second so that the transition between the second and the first sequences doesn’t involve a large jump in FI?
