Evidence suggests that at least some developmental mechanisms have been _______ during the evolution of multicellular organisms. Specific _______ comprise what is called the "_______."
A) conserved; protein sequences; genetic toolkit
B) highly modified; DNA sequences; genetic toolkit
C) conserved; DNA sequences; genetic toolkit
D) highly modified; protein sequences; developmental tool kit
E) conserved; DNA sequences; developmental tool kit

Question

Quizplus · Accepted Answer

The word "conserved" means that the developmental mechanisms have remained relatively unchanged during evolution. The genetic toolkit comprises the DNA sequences that are responsible for controlling these developmental mechanisms. Therefore, option C is the best choice because it accurately reflects the concept of conserved developmental mechanisms and the genetic toolkit.
