Two methods of biotechnology used by scientist are described below. Method X: Used genetic engineering to create a crop of corn that grows faster and is pest resistant

Method Y: used artificial selection to create a new breed of dog that sheds less.

Which method is likely to be more advantageous in agriculture? Thank you for answering!

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
