DNA contains the genetic instructions for a living cell's function. Chromosomes are thread-like structures that contain DNA and histone proteins.
A chromosome is a loosely defined term, and vary widely among different organisms.
DNA is a set of instructions, and chromosomes help fit the DNA molecules into a cell's nucleus. Chromosomes are essential units for cellular division and replication to insure genetic diversity.

ProfessorDNA is the molecule that carries genetic information in organisms, while chromosomes are structures made of DNA and proteins that contain the genetic material. Chromosomes are thread-like structures found in the nucleus of cells and are composed of tightly coiled DNA. DNA is the building block of chromosomes, with each chromosome containing large amounts of DNA.
The difference between DNA and a chromosome has to deal with an intermediary- genes. DNA is deoxyribonucleic acid, which is a nucleic acid. It is made up of four bases- adenine, cytosine, guanine and thymine. When these four bases are arranged in a segment, it is called a gene. When these segments of DNA or genes are compactly coiled so that it can be easily duplicated and separated, it is called a chromosome. So DNA compose genes, and chromosomes make sure that the genetic information is neatly and compactly stored for replication and transport to another cell created via mitosis or meiosis.

What is the difference between a chromosome and a DNA molecule?
A chromosome is a condensed structure of DNA and proteins found in the nucleus of a cell, while a DNA molecule is a long, linear molecule that carries genetic information in the form of genes. Chromosomes contain multiple genes and are visible under a microscope, while DNA molecules are individual strands that make up chromosomes.
How can you tell the difference between the original and replicated part of each chromosome?
In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
What is the order of size between codon chromosome nucleotide DNA and nucleosome?
The order of size from smallest to largest is as follows: nucleotide, codon, DNA molecule, chromosome, nucleosome. A nucleotide is the basic building block of DNA, a codon is a sequence of three nucleotides that encode for a specific amino acid, DNA is a long molecule that carries genetic information, a chromosome is a condensed structure of DNA, and a nucleosome is a structural unit of DNA wrapped around a core of histone proteins.
What is the difference between chromosomes and nucleosomes?
Chromosome Nucleosome
What is the most broadest category to most specific category in genetic material in DNA?
