Where in nucleic acids is genetic information stored?
Genetic Information are stored in chromosomes [ usually in nucleus ] :)
What is the job of the nucleus?
The Nucleus hold DNA
Description of chromosomes?
Chromosomes are counted differently depending on the stage of the cell cycle. To count the number of chromosomes, one could count the number of functional centromere. The number of DNA molecules is usually the number of chromatids.
What is the difference between chromatin and chromosome?
A chromosome is a strand of DNA with proteins, that is usually found within the cell's nucleus. On the other hand, chromatin is a mass of genetic material containing DNA, RNA, and various proteins that forms chromosomes.**before mitosis, the DNA is loose in the nucleus in the form of chromatin. When the DNA begins to undergo mitosis the chromatin condenses to form the chromosome.The difference between chromatin and chromosomes is that chromosomes help to make up chromatin. Chromatin is made up of DNA and proteins, and is what makes the nucleus of a cell. Chromosomes make up the DNA.
What is the major differences between a bacterial cell and the cell of other organisms?
All bacterial cells do not have a nucleus but the cells of other animal have nucleus which is usually spherical or oval in shape inside it there are chromosomes that form a dense tangle referred to as chromatin.
What is centromeres?
Chromosomes are thread like structures usually present in the nucleus that become visible only during cell divisions. Most chromosomes consist of two arms that extend out from a specialized region of DNA , called Centromere.
Where are chromosomes found in multicellular organisms?
Chromosomes are found within the nucleus of the cell (in Eukaryotic cells). There are also usually smaller chromosomes in the mitochondria and chloroplasts.

What category of cells does not have a nucleus or organelles?
Prokaryotes. These type of cells usually only have a genetic strand of chromosomes, some organelles (not membrane bound ones though) and no nucleus. These will usually be germs, viruses, and etc. Eukaryotes that the other type that are found to be all animal cells and they are completely different. They have membrane bound organelles and a nucleus.
What is the job of the nucleus?
The Nucleus hold DNA
Is chromosomes found in Golgi apparatus?
No, they aren't. They are found in the nucleus when the cell is in the division process.
Where is Chromosomal DNA located?
Chromosomes are located in the nucleus of a cell in eukaryotes. In prokaryotes (which lack a cell nucleus) chromosomes are circular in shape usually found attached to the plasmid membrane. Smaller circular DNA known as plasmids are also found in the prokaryotic cells and are thought of as smaller versions of chromosomes.

Where are the chromosomes of most organisms located?
In prokaryotic cells, the chromosome is attached to the cell membrane and is a single plasmid. In eukaryotic cells the (usually multiple) chromosomes are enclosed within the nucleus.

Where are the chromosomes situatedin a normal cell?
In eukaryotes (animals, plants, fungi, algae) chromosomes are found in the nucleus.There is also DNA in mitochondria and chloroplasts, which is usually referred to by terms like "mitochondrial DNA" or "the chloroplast genome". The word "chromosome" is not generally used for this DNA.Prokaryotes (bacteria) have a single chromosome in a region of the cell called the nucleoid. Scientists do not use the term "nucleus" for prokaryotes, as there are no membranes inside the cell, and therefore no nuclear membrane. So, no nucleus!The nucleus.
What color is Lugol's iodine?
The color of the chromosomes stained in a onion cell is usually a deep purple.
