chromosomes
A gene is a segment of DNA that codes for a protein.
chromatin. whereas the highley condensed linear sequence of dna which contains many different genes is called a chromosome
DNA --> RNA --> Proteins -----------------------------------------That simple.
When proteins are manufactured in a cell, they are always made in the form of a linear molecule, that is just one long sequence that goes in a straight line. That is because it is easier for cells to do it that way. Linear sections of DNA produce linear sections of RNA which then serve as the template for the synthesis of linear sections of protein. But once the protein is manufactured, it will in most cases fold up into some kind of three dimensional structure. The shape of the folded protein is essential to whatever biological function it has.

DNA in Eukaryotic cells are linear. DNA in Prokaryotic cells are circular.

All nuclear DNA in eukaryotes is linear DNA. Eukaryotic chromosomes, such as those in human cells, are linear DNA molecules spooled around support proteins called histones.
protein and DNA
DNA tells a ribosome how to assemble a protein.
That depends. DNA undergoing replication is assisted by varieties of proteins to make a new strand. Also, in order for DNA to be coiled into chromosomes, the DNA must be wrapped around the protein histone. But in the actual structure of DNA, no, there are no proteins.

Hepatitis B virus contains a linear DNA which is inclosed by nucleocapsid.
DNA determines a protein's shape by determining the sequence of the amino acids in a protein.
