The level of DNA packaging which is brought about by the formation of nucleosomes it looks like beads on a string.
In general terms, nucleosomes are termed as a basic unit of DNA packaging which is in eukaryotes.
It consists of eight segments of DNA wound. Nucleosomes form a fundamental unit which repeats the eukaryotic genomes to the nucleus by ensuring a well appropriate access to it.

The answer is nucleosomes in which a part of DNA that is wrap with proteins. In the nucleus the DNA forms with proteins that is called chromatin allowing the DNA to condense into a minute volume. Under the microscope this structure looks like a bead on a string.

Answer:

When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed.

How does the theory of endosymbiosis differ from the autogenous and horizontal gene transfer theories in explaining the evolutio

Llana [10]

<h3>Answer and Explanation;</h3>

Endosymbiotic theory explains the origin of chloroplasts and mitochondria and their double membrane. Mitochondria of eukaryotes evolved from aerobic bacteria living within their host cell and the chloroplasts of eukaryotes evolved from endosymbiotic cyanobacteria.
On the other hand according to the autogenous hypothesis, mitochondria and chloroplasts have evolved within the protoeukaryote cell by compartmentalizing plasmids or vesicles of DNA within a pinched off invagination of the cell membrane.

Endosymbiont theory is the theory that suggests that simple prokaryotic cells were engulfed by larger prokaryotes 1.5 billion years ago.
Autogenous theory is a theory that was proposed as an alternative to endosymbiont theory. proposes that eukaryotic organelles formed by infolding of the plasma membrane.
Horizontal gene transfer theory is an alternative to endosymbiont and autogenous theories for the origin of complex organelles in eukaryotes.
