Where in the cell would you find chromosomes?

You would find them in a nucleaus inside the cell.


What consists of DNA tightly coiled around proteins?

Chromosomes


What basic protein forms the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes?

Histones are the basic proteins that form the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes. These proteins help to package and condense the DNA within the cell nucleus.


In eukaryotic cells each chromosome has?

In eukaryotic cells, each chromosome has one or more DNA molecules, which are tightly coiled around proteins called histones. These DNA-histone complexes form chromatin fibers, which condense further to create distinct chromosomes during cell division.


How is Eukaryotic DNA organized?

Eukaryotic DNA is organized into chromosomes within the nucleus. DNA is wrapped around histone proteins to form nucleosomes, which further condense into chromatin fibers. These chromatin fibers coil and fold to compact into X-shaped structures called chromosomes during cell division.


Chromosomes is composed of DNA and proteins which are tightly compacted and condensed?

Yes, chromosomes are made up of DNA wrapped around histone proteins. This complex structure allows the genetic material to be tightly compacted and condensed, ensuring that it can be organized and efficiently segregated during cell division.


What eukaryotic chromosomes contain both DNA and protein tightly packed together to for a substance?

Eukaryotic chromosomes contain both DNA and protein tightly packed together to form Chromatin. Chromatin consists of DNA tightly coiled around histones. DNA and histone molecules form nucleosomes. These are all part of the structure of chromosomes.


What are chromosomes mostly made of?

Chromosomes are mostly made of DNA, which contains the genetic information of an organism. DNA is tightly coiled around proteins called histones to form chromatin, which then condenses into visible chromosomes during cell division.


How does the structure of a chromosome differ in a prokayote and eukaryote?

Eukaryotic cells have a double membrane, surrounding the nucleus, the organelle that contains several chromosomes. The prokaryote chromosomes are dispersed within the cell and is not enclosed by a separate membrane


What is the difference between prokaryotic and eukaryotic cells' DNA?

One main difference is that prokaryotic cells have a single circular chromosome located in the nucleoid region, while eukaryotic cells have multiple linear chromosomes housed inside a membrane-bound nucleus. Additionally, prokaryotic DNA is not associated with histone proteins, unlike eukaryotic DNA which is tightly wrapped around histones.


What is the role or proteins in a chromosome?

Chromatin is tightly coiled and wrapped around proteins called histones to form structures called chromosomes


Where chromsomes are found?

Chromosomes are found inside the nucleus of a cell. They are composed of DNA tightly wrapped around proteins called histones. Humans typically have 46 chromosomes, which come in 23 pairs.
