This is called a Chromatid. For example a Human Chromosome that is expanded at 32,000 micrometers long will loop {supercoil} around Histones and end up being just 6 micrometers long!

A portion of a DNA molecule wound around a spool of histone protein is called a?
Such a structure is called a Nucleosome
What organic substance is a nucleosome composed of?
Nucleosomes are the basic repeating units of chromatin which is a combination of DNA and proteins that make up the content's of a cell's nucleus. Nucleosomes are made of a histone octamer which is comprised of two of the following histones: H2A, H2B, H3, and H4. The histone octamer is bound and wrapped around approximately 146 base pairs of DNA and an additional H1 histone is added and is wrapped around 20 more base pairs.
Is chromatin made up of proteins and DNA or fats and proteins?
Chromatin is made up of DNA spirals. Chromatin makes up chromosomes.
How many different kinds of protein does one cell have?
There are thousands of different kinds of protein molecules in a typical cell. I personally researched this question for my homework and wound up finding the answer key, so I'm pretty sure it's the right answer.
What vitamin accelerates the healing of a wound?
if your asking for the vitamin, it would be vitamin c because it promotes collagen synthesis which is important for wound healing. other substances are also important in wound healing. protein is very much important for tissue repair and growth and adequate hydration is also good for faster healing.
A portion of a DNA molecules wound around a spool of histone proyein is called?
cell cycle

What causes the constriction in the condensed chromosome?
The Dna comprised chromosomes are wound around protein Histone Cores that are then in turn wound into a ten nanometer diameter strand that is then, in turn, wound into a thirty nanometer diameter strand - hense constriction.
What are strands of DNA wound around?
DNA coils around proteins called histones.
What structure allows enormous lengths of DNA to be folded into the nucleus?
The nucleosome. The nucleosome consists of DNA wound tightly around a protein called histone. This winding is sort of like coiling up a rope, and allows DNA to be packaged into a smaller space than would otherwise be achieved.

Is DNA made if chromosomes?
No. DNA is what chromosomes are made of. DNA is wound around proteins like thread on a spool, but since DNA is one long"string", the DNA is wound around many protein "spools", all of which are connected by DNA. This string of DNA/protein "thread on spools" is wound around itself, and wound around itself, and wound around itself a lot more, then (after a pretty intricate process) Wala! You have a chromosome.

How is a chromosome different from chromatin and how are they similar?
Chromosomes exist [in interphase] as de-condensed, or free, potential chromatin; while chromatin is chromosomes that are condensed [wound] around histone proteins. This condensation, or packing, of the chromosomes occurs in two stages: first the Dna strand is wound around Histone proteins that then spiral into The Ten Nanometer Fiber. This spiraled compact 10 nm fiber is then further wound up into the Thirty Nanometer Fiber, the chromatin, which is then further folded [condensed] into The Chromosomes.
Why there is a need to compact the DNA?
The 'short' Answer is 1.87 meters. Actually it is quite True that the linear length of Dna contained in a human Cell nucleus - typically 3 to 4 micrometers in diameter - is 1.87 meters long! "Folding" occurs in three phases - the first involves the winding of the Dna strand around histone proteins - next the strands of histone wound Dna are twisted into the 10 nm fiber. Then this 10 nm fiber is wound around itself into the 30 nm fiber: this is microscopically visualized as the Chromosome Strand(s).

When was Lace Around the Wound created?
Lace Around the Wound was created in 1989.
