Here's the question you clicked on:
Giovanni
in an mRNA molecule, a group of three nitrogenous bases makes up a codon, and each codon codes for an amino acid. there are 4 diff nitrogenous bases that can be arranged into different codons, but there are only 20 diff type of amino acids. based on this info what conclusionn can you make about the genetic code?
A.during translation nitrogenous n]bases are rearanged into a sequence tht corresponds to an amino acid
each coden can be translated into more than one possible amino acid
C, many possible combos
D.several diff codens result in proction of the same amino acid
The total number of combinations of 3 bases is 4 raised to the power of 3 or 64. So there could be 64 different codons.There are only 20amino acids, so I'll let you figure out the answer. As a hint I'll suggest you look at the genetic code: http://en.wikipedia.org/wiki/Genetic_code The RNA codon table should be the most relevant bit for this question. Best wishes
