Final answer:
Enzymes like DNA helicase and DNA polymerase are essential for unwinding DNA strands and adding complementary nucleotides during DNA replication, ensuring an exact copy of the genome is passed to new cells.
Step-by-step explanation:
Enzymes play a critical role in the process of DNA replication, which ensures that each new cell receives an exact copy of an organism's genome. During replication, enzymes such as DNA helicase unwind the DNA molecule and separate the two strands. Another key enzyme, DNA polymerase, then adds nucleotides one by one to the growing DNA chain that are complementary to the template strand. This process involves the synthesis of leading strands and lagging strands (via Okazaki fragments), with the leading strand synthesized continuously and the lagging strand synthesized in segments. DNA ligase and other enzymes and proteins also contribute to the completion and verification of DNA replication, ensuring the fidelity and accuracy of the process.
Enzymes play a crucial role in DNA replication. They unwind the DNA molecule, separate the two strands, and assist in the building of complementary strands along each parent strand. The enzyme DNA polymerase adds nucleotides one by one to the growing DNA chain that are complementary to the template strand. This ensures that each new daughter cell receives an exact copy of the organism's genome.
