Sequence Search
The following DNA base sequences are from a
segment of present-day human chromosome 2. The graphic represents the ancestral
condition of the chromosomes. In order for fusion to have occurred, the
head-end telomere of chimpanzee chromosome 2b would have had to invert and
rotate on its axis a half-turn to correctly join the head-end telomere of
chimpanzee chromosome 2a. If this occurred, the fossil remnants of this fusion
would be seen in modern human chromosome 2 in the form of a DNA sequence
showing head-to-head telomere DNA. If the two ancestral chromosomes fused, what
would the sequence be at the fusion point? Write down the remainder of the DNA
sequence in the graphic below. Then search the code below for the string of
letters that most closely matches the top line of chimp 2a and chimp 2b segments in the graphic.
(Mutations may have caused some letters to change.)
