DNA has a net negative charge (which is due to the phosphate backbone) and is Acidic nature and histones which have a pI of ~10 are basic and overall have a positive charge (histones are right in argenines and lysines). Opposites attract, + and - are attracted. :) hope this helps

DNA is wrapped around a special protein?
DNA is wrapped around histone proteins. They are called nucleosomes and resemble "beads on a string" when viewed closely.
What is the enzyme that unwinds the DNA from around the histone proteins?
Helicase
What is DNA tightly wrapped around?
The protein histone primarily.
How do chromosomes turn into DNA?
Replication chemicals trigger during cell replication trigger DNA to wrap tightly around histone octamers (histone proteins) to create nucleosomes, for DNA synthesis. This happens during the prophase stage of cell replication.
What are the names of the proteins DNA strands wind themselves around to condense into chromosomes?
Histone proteins
What is DNA wrapped around in a nucleosome?
They're called histone proteins. There are 8histones proteins in which a loop of DNA wraps around twice. Then another histone protein called the H1 linker binds them together.
What is the diameter of the DNA molecule?
The diameter of the alpha helix structure of DNA is 2nm, the diameter after having wrapped around the first histone is 11nm. That string wraps around another histone forming a 30nm chain, and so forth until you reach the chromasomal structure of roughly 700nm.
Does histones and DNA molecules relate to each other?
Histones are a part of DNA. Histones are actually 8 molecule of proteins joined together and the DNA strand wraps around the the histone in a circular manner. Histones are present on the DNA strand at regular intervals.
DNA is wrapped around a special protein?
DNA is wrapped around histone proteins. They are called nucleosomes and resemble "beads on a string" when viewed closely.
What is histone core?
A Histone Core is a group of Histone Proteins, mainly used in eukaryotes to package DNA strands into Nucleosomes. (Think of it like a spool for the DNA to wrap around, to be easily stored on a shelf)
What is the enzyme that unwinds the DNA from around the histone proteins?
Helicase
What is DNA tightly wrapped around?
The protein histone primarily.
What is the differences between a chromosome and a DNA molecules?
Somewhat the difference between a brick and a brick wall. Chromosomes are made up of DNA molecules collected in units called genes ( leaving all else aside ) with attendant proteins, such as the histone proteins DNA wraps around.
What is the DNA material within a cell that wraps around proteins called?
DNA wraps around proteins to form a prokaryotic cell.
What is histon?
A Histone Core is a group of Histone Proteins, mainly used in eukaryotes to package DNA strands into Nucleosomes. (Think of it like a spool for the DNA to wrap around, to be easily stored on a shelf)
How many times does DNA loop around the histone proteins in the nucleosome?
Twice
How do chromosomes turn into DNA?
Replication chemicals trigger during cell replication trigger DNA to wrap tightly around histone octamers (histone proteins) to create nucleosomes, for DNA synthesis. This happens during the prophase stage of cell replication.
