Chromosome duplication occurs prior to both mitosis and meiosis.Group startsTrue or False

True.

Chromosome duplication, also known as DNA replication, occurs prior to both mitosis and meiosis during the cell cycle's S phase (synthesis phase). In mitosis, which is the process of cell division that results in two genetically identical daughter cells, chromosome duplication ensures that each daughter cell receives an exact copy of the parent cell's chromosomes.

Similarly, in meiosis, which is the specialized form of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes, chromosome duplication also occurs before the meiotic divisions (meiosis I and meiosis II). This duplication is crucial as it allows for genetic material to be halved and redistributed among the resulting gametes while maintaining genetic integrity within the organism.

In summary, the statement is true because chromosome duplication is a fundamental process that is essential for both mitotic and meiotic cell divisions, facilitating accurate genetic distribution and maintaining genomic stability.
