Proteins are

a) built in the nucleus by dna and transported to the ribosomes.
b) converted from nucleic acids to amino acids in the nucleolus.
c) produced in the lysosomes and transported out of the cell by vacuoles.
d) transported to other parts of the cell by the endoplasmic reticulum from ribosomes.

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.
