Explanation:
Salvatore who is a typical adult eating a well balance diet chances would be he will not need then to take vitamin supplements which is the answer. A balance diet is needed to have good health. It means to eat plenty from the 4 main groups and limit smaller from 5th group.
Answer: The reason is because DNA polymerase which is the enzyme that catalyzes the synthesis of DNA has a 3'->5' exonuclease activity that double-checks each nucleotide after it is added.
Explanation: The 3'->5' exonuclease activity of DNA polymerase allows the enzyme to double-check and remove a newly added wrong nucleotide. It is highly specific for mismatched base pairs. When the DNA polymerase adds a wrong nucleotide to the growing strand, translocation of the enzyme to the position where the next nucleotide is to be added is halted, but the exonuclease activity of the DNA polymerase removes the incorrectly paired nucleotide so that replication can continue. The process of double-checking a newly added nucleotide and removal of any incorrectly paired nucleotide by the DNA polymerase is called proofreading.
The right option is; nucleotides
Nucleotides are the building blocks of DNA macromolecules.
Nucleotides are the building blocks (monomers) that make up a DNA molecule. Each nucleotide that constitutes DNA has three components which are; a five-carbon sugar (ribose or deoxyribose), a nitrogenous base, and a phosphate group. Nucleotides perform several important roles in the cell. They transfer chemical energy to cellular functions that require energy such as in proteins synthesis, and in the movement of the cell. Nucleotides are also involved in cell signaling.
