Guida verificata passo dopo passo1
Understand the cell cycle: The cell cycle consists of interphase and the mitotic phase. Interphase is further divided into three phases: G1, S, and G2.
Identify the role of each interphase phase: G1 phase is for cell growth, S phase is for DNA synthesis, and G2 phase is for preparation for mitosis.
Focus on the S phase: During the S phase, DNA replication occurs, resulting in the duplication of DNA in the form of chromatin.
Differentiate between chromatin and chromosomes: During interphase, DNA is in the form of chromatin, which is less condensed than chromosomes.
Conclude that the S phase is responsible for DNA duplication: Since the S phase is dedicated to DNA synthesis, it is the phase responsible for the duplication of DNA in the form of chromatin.
