DNA Replication & Cell Division Coordination — NEET Biology
📚 Practice ConceptFurther, not every detail of replication is understood well. In eukaryotes, the replication of DNA takes place at S-phase of the cell-cycle. The replication of DNA and cell division cycle should be highly coordinated. A failure in cell division after DNA replication results into polyploidy (a chromosomal anomaly). You will learn the detailed nature of origin and the processes occurring at this site, in higher classes.
Assertion (A): DNA replication is restricted to a specific phase of the cell cycle in eukaryotes. Reason (R): In eukaryotes, DNA replication takes place during the G1 phase of the cell cycle.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT confirms DNA replication is restricted to a specific cell cycle phase, making the Assertion true. However, NCERT states “In eukaryotes, the replication of DNA takes place at S-phase of the cell-cycle” - the Reason incorrectly places replication in G1 phase instead of S-phase.
