I am trying to solve an exercise.
How many nucleotides does a gene contain if information about 287 amino acids is encoded in it? What is the molecular mass and length of this gene?
AFAIK, I have to consider two DNA chains to find molecular mass, and one DNA chain to find the length of the gene (am I right here?).
But I am stuck trying to find how many nucleotides are there in a gene. Should I consider both or only one DNA chain? I suppose that both (as for the molecular mass of the gene) but I am not totally sure.
