Mark the following statements about the cell cycle as true or false. If a statement is false, correct it to make a true statement.
The main enzyme that builds the new DNA strands during DNA synthesis is RNA synthetase.

검증된 단계별 안내

Understand the context of the cell cycle: The cell cycle consists of several phases, including interphase (G1, S, G2) and mitotic phase (M). DNA synthesis occurs during the S phase of interphase.

Identify the role of enzymes in DNA synthesis: During the S phase, the main enzyme responsible for building new DNA strands is DNA polymerase, not RNA synthetase. RNA synthetase is involved in RNA synthesis, not DNA replication.

Evaluate the statement: The statement claims that RNA synthetase is the main enzyme for DNA synthesis. This is false because DNA polymerase is the correct enzyme for this process.

Correct the false statement: Replace 'RNA synthetase' with 'DNA polymerase' to make the statement true. The corrected statement should read: 'The main enzyme that builds the new DNA strands during DNA synthesis is DNA polymerase.'

Review the corrected statement: Ensure the corrected statement aligns with the biological process of DNA replication during the cell cycle and accurately reflects the role of DNA polymerase.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Cell Cycle

The cell cycle is a series of phases that a cell goes through to grow and divide. It consists of interphase (G1, S, G2) and the mitotic phase (M). Understanding the cell cycle is crucial for recognizing how cells replicate their DNA and prepare for division, which is fundamental in biology and medicine.

DNA Synthesis

DNA synthesis, or DNA replication, is the process by which a cell duplicates its DNA before cell division. This process occurs during the S phase of interphase and involves enzymes that synthesize new DNA strands complementary to the original strands, ensuring genetic continuity. The main enzyme responsible for this is DNA polymerase, not RNA synthetase.

Enzymes in DNA Replication

Enzymes play critical roles in DNA replication, facilitating the unwinding of the DNA double helix and the synthesis of new strands. DNA polymerase is the key enzyme that adds nucleotides to form new DNA strands, while other enzymes, such as helicase and ligase, assist in unwinding the DNA and joining Okazaki fragments, respectively. Understanding these enzymes is essential for grasping how DNA replication occurs accurately.
