Chromatin is a part of the spindle apparatus
Explanation:
Chromosome is not only responsible for genetic material. Chromatin is that substance which consists of protein and DNA. Here DNA carries genetic instruction. Histones are main proteins of chromatin. It is also called the packaging of element for the DNA.
In two forms chromatin exist. One is euchromatin and another is heterochromatin. Euchromatin is less condensed and it can be transcribed. Heterochromatin is highly condensed and typically not transcribed. Chromosomal pathway regulates spindle assembly.
The biological term is a pedigree.
