A young scientist has discovered a new species of grub worm in the Amazon. He would like to explore the possibility that in this grub worm the codon CUC is the start codon and codes for methionine, not leucine as it does in other worms. To date, he has been unable to get his research funded, most likely because
A) worms have been extensively studied and their genomes are simple.
B) worms do not contain homologous genes to humans.
C) codons are generally the same in all worms.
D) the genetic code is universal to all species.
E) worms are difficult to maintain in the laboratory.
Ans: D) the genetic code is universal to all species.
