1. where are proteins made?
2.how are they made?
2.how are they made?
1. in the cell cytoplasm on ribosomes.
2. ribosomes use the code in DNA. DNA in the nucleus is carried by mRNA which involves copying the DNA code and carrying it to the ribosomes. The correct amino acids are brought to the ribosomes in the correct order
