# There are 4998 nucleotides in a double-stranded DNA molecule. Determine how many amino acids the protein synthesized

There are 4998 nucleotides in a double-stranded DNA molecule. Determine how many amino acids the protein synthesized from this DNA sequence contains. The intron region accounts for 15% of the total number of nucleotides. Intron is a region of DNA that does not carry information about a protein molecule. Let’s determine how many nucleotides remain in the exon part of the DNA molecule: 15% = 4998 * 15: 100 = 749.7.
4998 – 749.7 = 4248.3 – this is how many nucleotides are contained in the exons of DNA.
Since a DNA molecule contains two chains, and protein synthesis occurs with only one, we calculate how many nucleotides are in one chain of a DNA molecule: 4248.3: 2 = 2124.15.
The genetic code is triplet, that is, one amino acid is encoded by three nucleotides. Accordingly, there are three times less amino acids than nucleotides: 2124.15: 3 = 708.05. Let’s round up the received answer to the nearest whole number: 708.05 = 708. Remember: The process of learning a person lasts a lifetime.
