A chemical called phenol (carbonic acid) destroys proteins but not nucleic acids, and strong alkali such as

sodium hydroxide destroys both protein and nucleic

acids. In the transformation experiments with

Streptococcus pneumoniae, what result would be

expected if the S-strain extract had been treated with

phenol? If it had been treated with strong alkali?

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.
