Gene- DNA - Chromosome- Nucleus
Explanation:
A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organisms cell and also pass genetic traits to offsprings. Hence, it is the molecular unit of heredity in living organisms.
The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A,C,G,T).
In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.
The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).
