DNA need to change periodically from a long double-helix chromatin molecule into a tightly wound-up chromosome?

When the DNA is an open chromatin molecule, portions of it are actively being transcribed by mRNA. The cell will then be using those instructions to manufacture amino acid chains and proteins. When the DNA winds up into a condensed chromosome it is preparing for mitosis, which would be very difficult to occur if the DNA were all stretched out.

Molecules consisting of DNA plus proteins?
A virus is such a molecule. Histones
How many DNA molecule in a chromatid?
Each chromosome is originally made of one DNA molecule.
When a chromosome has been duplicated it consists of two identical pieces attached together called?
A chromosome is a long, highly coiled strand of DNA. When the cell is undergoing replication, the DNA strand will replicate to form two identical copies, one copy goes to each daughter cell. However, a human cell consists of 23 paired homologus chromosomes to give 46 chromosomes in total.
Does each chromosome have a very long DNA molecule with hundreds of thousands of genes?
yes
After replication each chromosome harbors what?
two sister chromatids
Molecules consisting of DNA plus proteins?
A virus is such a molecule. Histones
What molecule makes up a chromatid?
Chromatin
What is the difference between a chromosome and a DNA molecule?
The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.
What is a single molecule of DNA and associated proteins?
a Chromosome
what organic molecule is found in the chromatin of cells?
DNA and protein
Which molecule is wound up to make a chromosome?
DNA molecule
A molecule of DNA is packaged and carried by a larger molecule called a?
Chromosome
What is the large molecule found in a chromosome?
GENETICS
Is a chromosomes a DNA molecule?
Yes, chromosomes are made of DNA and protein molecules called histones. Edit from another user: False, they're made of material called chromatin. Edit from user #3: Chromosomes and chromatin are actually the same thing, except in different form. Both chromosomes and chromatin are made up of a strand of DNA wrapped around histone protein, except chromatin is in a long and stringy form while chromosomes are a compacted and twisted version of chromatin.
Is euchromatin transcribed?
Euchromatin is a lightly packed form of chromatin which is the molecular substance of a chromosome. It is often but not always actively transcribing which means the information in a strand of DNA is copied into a new molecule of RNA.
What is the Long molecule in a chromosome?

How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
