What part of DNA provides the code for proteins?

nucleotide base

A nucleotide base -- a ringed molecule containing nitrogen -- hangs off each sugar group, and it's the sequence of these bases that contains the genetic code for creating proteins.

I think.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

did you fail the test? xd
