In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
<span>Cho finds a dinosaur tooth while on a school field trip. She has found an original-remains fossil . </span>Original remains can be
changed, as minerals in nearby sediments
are stored into the porous areas of an
animal’s hard parts (teeth in this instance) after the soft parts have
decayed. This happens with dinosaur bones and teeth. <span>

Answer:
Genome, chromosomes, and genes are all different DNA structures related to each other.
Explanation:
The genome is the set of hereditary material of an organism, the sequence of nucleotides that specify the genetic instructions for its development and functioning and that are transmitted from generation to generation, from parents to children.
The genome is organized into chromosomes, chromosomes are X-shaped supercoiled DNA structures. Each species has a characteristic number of chromosomes. In the human species each somatic cell has 22 pairs of autosomal chromosomes and one pair of sexual chromosomes (X and Y).
A gene is a unit of DNA information that encodes a functional product, such as proteins. Genes represent approximately 1.5% of the genome. Each gene have a location within the chromosomes called locus.
