What is the relationship between the chromosome scaffold of dividing cells and the matrix of interphase cells

A. The same DNA fragments that are found within the nuclear matrix in vivo can be retrieved from the metaphase scaffold
B. Fragments containing MAR sequences can bind to a metaphase scaffold; it is likely that DNA contains a single type of attachment site.
C. In interphase cells the attachment site is connected to the nuclear matrix, whereas in mitotic cells it is connected to the chromosome scaffold.

#Unit 2. Cellular Organization

A. The histone H3 variant Cse4 is incorporated in the centromeric nucleosome.
B. The CBF3 protein complex that binds to CDE-III is essential for centromeric function.
C. The proteins that bind CEN serve as an assembly platform for the kinetochore and provide the connection to microtubules.
