Hi Ari. I haven't finished the homework either. And Mr. Bird is out today.
The percentage is 89%. Took this test and got the same exact question.
Soil, water and food are all nonliving reservoirs of infection
The genetic code is based upon reading 3 bases at a time
there are 4 nucleotides bases in DNA and 20 amino acids .
In order to incorporate all the amino acids we consider 3 bases in genetic code
4 x 4 x 4 = 64
if we would take 2 bases -
4x4 = 16 that would leave out 4 amino acids without a code .
