1.	at which point two sister chromatin are held together - ??
Answer» The condensed chromatin is folded and tightly coiled, like a coiled telephone cord, allowing the cell’s DNA to be packed into the nucleus.Before a cell can divide, it must first replicate its DNA so that each of the two daughter cells will receive a complete copy of the DNA. The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere.
