Question 3

Explain how DNA controls the way proteins are made.

Answer 3

The genetic code is found within the nucleus.
When a cell needs to make a protein, the DNA, a code made up of bases, unzips itself.
The bases are grouped in triplets and
each triplet is a code for an amino acid.
Amino acids then join together to form proteins.
