a new restriction enzyme is discovered that recognizes an 8-base restriction seq

Question

a new restriction enzyme is discovered that recognizes an 8-base restriction sequence. About how many fragments of the wombat genome (approximately 4.2 ' 108 in size) would you expect if you digested it with this enzyme? Any reasoning would be great!

Explanation / Answer

8 base restriction enzymes are called as rare cutter enzymes. These restriction sequences occur very rarely in the genome.

A 8 base cutter enzyme cuts the genome for every 48 bps (65536 bps)

So number of fragments of the wombat genome (4.2 x 108) digested with 8 base restriction sequence would be 6408 approx
