1) How do nitroen bses along a gene serve as a genetic code?
2) Where in a cell does protein synthesis take place?

1. Triplets of nitrogen bases (also known as "codons") specify each amino acid to be inserted into a protein. For example, the triplet ATG signifies the amino acid methionine (and also the "start" of protein synthesis.
2. Although the DNA code is located in the nucleus, protein synthesis actually takes place in the cell cytoplasm (on structures known as "ribosomes").

Read your text or your notes to answer #1. Look for the code where 3nucleotides code for 1 amino acid. The order of the amino acids controls the form and function of proteins.
Protein synthesis takes place in the cytoplasm at the rough ER. NOT in the nucleus where transcription (DNA-->RNA) happens.

Im only 15 so the answer won't be in most intricate thing you're going to get but in reference to number 1 it has to do with the pattern in which the bases are formed on a strand of DNA, Adenine and Thymine can be matched and Cytosine and Guanine can be matched I believe. The pattern in which these are arranged in DNA(ie. AT GC CG, etc.) will determine traits
