A structure that holds two duplicate chromosomes together is called a centromere. The centromere is a region of the chromosome where the two sister chromatids are joined and where the microtubules of the spindle apparatus attach during cell division to ensure proper chromosome segregation.
Chromosomes duplicate during the S phase of interphase in the cell cycle. This is when DNA replication occurs, resulting in each chromosome being duplicated to form two sister chromatids held together at the centromere.
If two elements are joined together it is a compound
Yes, nucleic acids can duplicate themselves through a process called replication, which involves unwinding the DNA double helix and synthesizing two new strands that are complementary to the original strands. This process ensures that genetic information is passed on accurately during cell division.
