Final answer:
The assertion that large tandem repeats exist near some centromeres, specifically in the pericentromeric regions of chromosomes 1, 9, and 16, is true. These regions are complex and contain various types of DNA sequences that contribute to chromosome function and division.
Step-by-step explanation:
The statement that large tandem repeats other than the alpha-satellite family are found within the vicinity of some centromeres, specifically in the pericentromeric regions of chromosomes 1, 9, and 16, is true. The human genome contains various types of repetitive sequences, including tandem repeats, interspersed repeats, and satellite DNA.
In relation to centromeres, which are key structural components essential for correct chromosome segregation during cell division, the pericentromeric regions often contain large tandem repeats. These repeats are crucial for the formation of a proper chromosome structure and function during mitosis and meiosis.
While alpha-satellite repeats are the primary DNA sequence component of functional centromeres, the pericentromeric regions may contain other tandem repeats that can play a role in chromosome stability and dynamics. This complexity reflects the intricate organization of chromosomes that goes beyond the familiar repeat structures of telomeres, which are meant to protect the ends of chromosomes.
