Answer 1

Answer:

1.......Within chromosomes, DNA is held in complexes with structural proteins. These proteins organize the DNA into a compact structure called chromatin. In eukaryotes, this structure involves DNA binding to a complex of small basic proteins called histones.

2.....The point of attachment between two sister chromatids is called the centromere. The centromeres also serve as microtubule-organizing centers during prophase in an assembly called the kinetochore.

3.......The root tip has three main zones: a zone of cell division, a zone of elongation, and a zone of maturation.
