|
|
the final number of chromosomes is reduced by half in both

Detailed explanation-1: -o, the correct statement is ‘In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage. ‘
Detailed explanation-2: -DNA replicates before actual cell division so that identical set of the genome of the parent cell is received by each daughter cell.
Detailed explanation-3: -Answer and Explanation: This statement is false. Prior to the start of meiosis II, the dividing cell will be in a stage called interkinesis that resembles interphase. However, unlike interphase, no further DNA replication will occur during this stage.
Detailed explanation-4: -DNA replication takes place in S-phase of the Interphase before Meiosis I begins.
Detailed explanation-5: -Which of the following occur in both mitosis and meiosis? Explanation: The separation of sister chromatids is the only item of the answer choices that occurs in both mitosis and meiosis.
