What fragment would remain if the DNA fragment 5'-TCCTGTACAACGACC-3' were cut using a restriction enzyme that has a four base pair palindromic recognition site? After the cut, two bases are left unpaired as sticky ends and a base pair at each end of the palindrome is left paired.

answer; i believe the correct answer to the above question is ( friction)

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
