What role do proteins play in enabling the enormous amount of DNA in a eukaryotic cell to lit into the nucleus and what are those proteins called?
Histones are proteins which help to tightly pack the DNA into the nucleus of eukaryotic cells. A histone octamer (8 histones together= 2 of H3, 2 of H4, 2 of H2A and 2 of H2B) is formed and the DNA is wrapped 1.65 times around these 8 tightly packed histones forming a nucleosome. There are many nucleosomes along the DNA and together they look similar to a pearl necklace, with the beads being the nucleosomes. The nucleosomes can then be packed together even more tightly (like in heterochromatin) by other proteins.

Name two differences between the heredity material of a prokaryotic cell and a eukaryotic cell?
Prokaryotic cells have a single circular chromosome, while eukaryotic cells have multiple linear chromosomes. Prokaryotic cells lack a nucleus and their DNA is not associated with histone proteins, whereas eukaryotic cells have a nucleus where their DNA is stored and packaged with histone proteins.
Is chromatin an organelle?
Yes it is an organelle.
What contains genetic material of a eukaryotic cell?
The nucleus holds the cells genetic material in eukaryotes. The genome of eukaryotes is sequestered to a membrane bound organelle called the nucleus. The nucleus is the site of replication and transcription.
Why does transcription occur in the nucleus and not in the cytoplasm in eukaryotic cells?
Transcription occurs in the nucleus of eukaryotic cells because that's where the DNA is located. The DNA in the nucleus serves as the template for making RNA, which is the first step in protein synthesis. The cytoplasm, where ribosomes are located, is where translation occurs, using the RNA made in the nucleus to build proteins.
Difference between eukaryotic cell and prokaryotic cell?
Eukariya means true nucleus.Main difference is Eukariyotes have a nucleus.Having membranous organells is identical to eukaryotes.
What role do proteins play in enabling the enormous amounts of DNA in the eukaryote cell to fit into the nucleus and what are the proteins called?
DNA that is not being "used" by the cell is wrapped up around proteins called histones.

How does eukaryotic cell us instructions from the nucleus to make proteins?
It nothing at all
How does a Eukaryotic cell use instruction from the nucleus make proteins?
It nothing at all
Does prokaryotic or eukaryotic cells contains nucleus?
No. Only the eukaryotic cells have a nucleus.
What are three components of a typical eukaryotic?
The three main components of a eukaryotic cell is the plasma membrane, cytoplasm, and nucleus. The plasma membrane consists of proteins, phospholipids, and cholesterol.

Are chromosomes found in the nucleus of eukaryotic cells?
there is no nucleus in eukaryotic cells, the chromosomes are found in the mitochondria
