QUESTION:
Why do the chromosomes line up in the middle of the cell?
ANSWER:
Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.

Answer:
After one round of replication, there will be only two layers one of 14 N and second of 15 N labelled. This is because of total conservation of template. If it was semi-conservative then an intermediate layer will be formed composed of one strand of 14 N and other strand of 15 N. This intermediate strand did not appear in this conservative replication state.
