WebSister chromatids are held together by proteins at a region of the chromosome called the centromere. Chromosomes undergo additional compaction at the beginning of mitosis. When fully condensed, replicated chromosomes appear as thick X-shaped structures that are readily observed under the microscope (see figure below). Web6 de abr. de 2024 · Sister chromatids are formed during DNA replication, when the DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. The resulting two identical DNA molecules remain joined together as sister chromatids until they separate during cell division.
