DNA is divided into several linear bundles called chromosomes, are separated by a microtubular spindle during nuclear division
The DNA usually divides into a number of linear bundles referred to as chromosomes that are usually separated by a microtubular spindle during nuclear division.

Chromosomes are composed of Supercoils.
DNA molecules are spiraled into a double helix.
This helix is then wrapped around a special molecule called a Histone.
Histones are kept in place by the DNA and form structures called Nucleosomes.
Nucleosomes are then coiled even further into a huge structure called a supercoil.
The supercoil in then coiled even more and eventually forms a chromosome.
So, chromosomes are made from just two 'Supercoils'; [see Histone Proteins], the 10 nm beads for the thin coil and the 30 nm 'beads' for the thick coil.

What chemical complex is eukaryotic chromosomes are composed of a complex of 60 percent protein and 40 percent DNA?
Chromatin
Which came first Eukaryotes or oxygen Accumulation in the Atmosphere?
Oxygen came before Eukaryotes and this is known due to the fact that Eukaryotes need oxygen to live.
Where were the atoms in your body formed?
Everything is composed of atoms. So your atoms initially began forming inside the fertilised egg in which you began to exist.
What happens to chromatin when the cell divides?
Chromosomes pair up with their partners and then divide, and are distributed into cells after 2 nuclear divisions so that 4 cells are formed. Then these develop into gametes. The result is that each gamete contains half the normal number of chromosomes possessed by any ordinary body cell.
What is the definition of coal?
Coal is rock composed mostly of carbon, hydrogen, and oxygen. Coal is formed from the remains of ancient plants buried in the crust of the earth for millions of years.
What difference between chromosome of prokaryote and eukaryote?
Chromosomes of eukaryotes are composed of DNA and protein. Chromosomes of prokaryotes have DNA only.
Prokaryotes are distinguished from eukaryotes in that they have no?
Chromosomes
Of what materials are chromosomes composed?
Chromosomes are composed ofDNAHistone proteins
Loading During cell division what structures do the DNA of eukaryotes bunch into?
Chromosomes
How is the chromosomes in the eukaryotes different from the structer of chromosomes in prokaryotes?
in eukaryotic chromosomes it produces DNA to live and in prokaryotic chromosomes it is nothing but bacteria.
How does the structure of a chromosome differ in a prokayote and eukaryote?
Eukaryotic cells have a double membrane, surrounding the nucleus, the organelle that contains several chromosomes. The prokaryote chromosomes are dispersed within the cell and is not enclosed by a separate membrane
Number of origins of replication on the chromosomes of eukaryotes?
High
A tetrad is composed of?
Tetrads are formed of 2 homologous chromosomes, which are crossing over so there is a total of 4 chromatids. :D
Where chromosomes are in a cell?
Chromosomes are found in the nucleus of animal cells (eukaryotes). In bacteria and archaebacteria, they float freely in the organism.
Why does the adder's tongue fern have more chromosomes than eukaryotes?
because
During mitosis chromosomes are moved and separated through the use of spindles composed of?
microtubules. These microtubules are formed from the centrosomes and attach to the chromosomes at their kinetochores. As the microtubules shorten and lengthen, they pull the chromosomes apart, ensuring that each daughter cell receives the correct number of chromosomes.
Of what are chromosomes composed?
Chromosomes are DNA wrapped around histones
