Protein is made up of 100 amino acids. Determine the number of nucleotides in the DNA molecule that encodes this protein.
One amino acid is encrypted in three nucleotides at once. If the protein contains 100 amino acids, then the mRNA, which will be used for the synthesis of this protein, contains:
100 * 3 = 300 nucleotides.
The DNA chain along which this mRNA is built will also have 300 nucleotides. However, a DNA molecule consists of two strands. Therefore, in the DNA molecule encoding this peptide, there will be:
300 * 2 = 600 nucleotides.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
