Eukaryotic cells maintain the correct balance of deoxyribonucleotides needed in a species DNA by ________.

Question

Quizplus · Accepted Answer

Eukaryotic cells maintain the correct balance of deoxyribonucleotides needed in a species DNA by controlling both the specificity and activity of ribonucleotide reductase at the same time. Ribonucleotide reductase is an enzyme that converts ribonucleotides to deoxyribonucleotides, which are used for DNA synthesis. This enzyme is regulated in a complex manner, with multiple levels of control, including allosteric regulation, post-translational modifications, and gene expression. By controlling both the specificity and activity of ribonucleotide reductase, eukaryotic cells ensure that the correct balance of deoxyribonucleotides is available for DNA synthesis, while also preventing the accumulation of toxic intermediates.
