Several; DNA is super-coiled in its chromosomal state. It coils like this with the assitance of packaging proteins such as histones, condensins and cohesins. Different chromosomes (and organisms) have different packaging ratios. For example, the shortest human chromosome has an un-coiled DNA length of about 14,000 micrometers. In its chromosomal state, it has a length of about 2 micrometers, giving it a packaging ratio of 7,000.
What else can I help you with?
Number of DNA molecules in a chromosomes?
Each chromosome contains a single DNA molecule that is highly compacted and coiled around proteins. This single DNA molecule contains all the genetic information for an organism.
Is it true or false The length of DNA ina chromosome may be as much as 10000 times as long as the chromosome itself?
True. The DNA in a chromosome is tightly packaged and condensed, so the actual length of DNA in a chromosome can be much longer than the physical length of the chromosome itself. This is possible due to the coiling and folding of DNA around histone proteins to form chromatin, allowing for a significant amount of genetic material to be compacted within a small space.
Is the chromosome a part of a DNA or is a DNA a part of a chromosome?
The second statement would be more correct.
What is the most broadest category to most specific category in genetic material in DNA?
genome -> chromosome -> DNA -> gene
How is a regular chromosome different from a super chromosome or duplicated chromosome?
A regular chromosome consists of a single, linear DNA molecule containing genetic information. In contrast, a super chromosome, often found in certain organisms, is a highly compacted structure that can contain multiple genes and regulatory elements, significantly enhancing gene expression and function. A duplicated chromosome, on the other hand, consists of two identical sister chromatids joined at the centromere, resulting from DNA replication prior to cell division, and serves to ensure accurate segregation of genetic material during mitosis or meiosis.

What makes up a chromosome?
A chromosome is made up of DNA, protein, and RNA. The DNA contains the genetic information necessary for an organism's growth and development, while the proteins help the DNA stay organized and compacted within the chromosome structure. RNA is involved in various functions related to gene expression and regulation.

How many DNA strands constitute a chromosome?
every and any DNA strand can constitue to a chromosome :)
Is the chromosome a part of a DNA or is a DNA a part of a chromosome?
The second statement would be more correct.
How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
How many DNAmolecules make up each original chromosome?
A chromosome is formed from a single DNA molecule.
Is the chromosome number reduced by mitosis?
No,because mitosis is basically the movement of the organelles,during interphase (previous to the phases of mitosis) DNA is replicated and the cell grows. Although it may seem the DNA is being abolished,it isn't. DNA is actually being compacted in mitosis,not disappearing.
At the beginning of cell division DNA and the proteins associated with the DNA coil into a structure called an?
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
What are the 4 types of DNA?
autosomal dna, X chromosome, Y chromosome,and mitochondrial
