Three nucleotide represent a codon, which, when translated from mRNA to tRNA, codes for a particular amino acid in a polypeptide chain.
If there are 12 nucleotides, the number of mRNA codons can be calculated by dividing the total number of nucleotides by 3, since each codon consists of 3 nucleotides. Therefore, with 12 nucleotides, there would be 12 / 3 = 4 codons.
A minimum of 600 nucleotides is necessary to code for a polypeptide that is 200 amino acids long because each amino acid is coded for by a sequence of three nucleotides in mRNA. This is due to the genetic code being triplet, where every three nucleotides represent one amino acid.
One amino acid is encoded by 3 nucleotides. That means 150 amino acids are encoded by 150*3=450 nucleotides. But there are also Start and Stop condons, which are also encoded by 3 nucleotides each. Therefore, I guess, the theoretical minimum is 450 nucleotides and the full (maximum) should be 450+ 3+ 3= 456 nucleotides.
A three-nucleotide sequence makes up a codon.
A DNA sequence consisting of 12 nucleotides will produce 4 mRNA codons. This is because each codon is made up of 3 nucleotides, so you can divide the total number of nucleotides (12) by the number of nucleotides per codon (3), resulting in 12 ÷ 3 = 4 codons.
DNA polymerase I removes the RNA nucleotides from the primer and adds equivalent DNA nucleotides to the 3' end of Okazaki fragments in prokaryotes.
The number of nucleotides in a DNA sequence can vary, but in general, a human DNA molecule contains about 3 billion nucleotides.

To calculate the number of nucleotides required to code for a specific polypeptide, you need to know the number of amino acids in the polypeptide. Since each amino acid is coded by a codon made up of three nucleotides, you would need 3 times the number of amino acids to determine the total number of nucleotides required. For a 150 amino acid polypeptide, the number of nucleotides would be 150 (amino acids) * 3 (nucleotides per amino acid) = 450 nucleotides.

The enzyme responsible for adding nucleotides to the 3' end of a growing DNA strand is called DNA polymerase.
