If science is to be defined at,
science is a systematized body of knowledge. Science is where the organized set
of facts were obtained and is used as a tool, model or paradigm to gather such
evidential data. Science is not a fact but an existential body in which comprises
the study of the anatomy and physiology of a certain object by the means of
observation, hypothesis, experimentation, interpretation and conclusion of the
gathered facts. Or what others would describe the scientific process.

The mechanics of cytokinesis are not yet completely understood, but a great deal is known about the critical timing of its events and other aspects of the final step in the cycle of any one cell. The four stages of cytokinesis are initiation, contraction, membrane insertion and completion .
A bilayer of phospholipids.
Answer:
a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin
b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins
Explanation:
The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.
