20 Amino Acids
3 base pairs (3 letters) code for 1 aminoacid and this 3 base pair sequence is called a codon.

The genetic code is based on a 3 base sequence because the anticodon on the transfer RNA consists of a 3 base sequence. Each transfer RNA carries one amino acid, and the anticodon, the area that attaches to the corresponding codon in the messenger RNA during translation, is only 3 bases long.

Assuming you do not have a typo in your question, a codon is a triplet of adjacent nucleotides in the messenger RNA chain that codes for a specific amino acid in the synthesis of a protein molecule.

300 nucleotides are needed to code for a polypeptide that is 100 amino acids long, because each amino acid is coded for by a sequence of 3 nucleotides (codon), and there are 100 amino acids in the polypeptide.
To code for a protein of 150 amino acids, the DNA molecule would need approximately 450 base pairs. This is because each amino acid is encoded by a sequence of three nucleotides called a codon. So, 150 amino acids would require 150 codons, which translates to 450 base pairs.
The DNA sequence TCAGCCACCTATGGA codes for the mRNA sequence UCAGCCACCUAUGGA, which translates to the amino acids Serine-Alanine-Threonine-Tryptophan. Therefore, this DNA sequence codes for 4 amino acids.
A deletion of one nitrogen base would result in a frameshift mutation in the DNA sequence that codes for proteins. This would likely affect all amino acids downstream of the deletion site, leading to a significant alteration in the protein's primary sequence and possibly its function.
Each triplet of nitrogenous bases on DNA, called a codon, codes for one amino acid. Therefore, the number of amino acids coded for by the original DNA model would be equal to the number of codons present in the DNA sequence. This would be determined by dividing the total number of nitrogenous base pairs in the DNA sequence by three.
There are 64 codons (3-base code) that represent 20 amino acids and 3 stop signals. Click on the related link to see a table of DNA codons and the amino acids for which they code.
