The following earlier provided answer, I believe, is wrong:

"A gene is not a single structure or thing. It is made up of the micro-structures that determine a trait. These micro-structures are primarily chromosomes. Chromosomes are pieces of DNA. A single strand of DNA stretched out would be about 3 feet long. A common analogy is that DNA is like the strands of a necklace and the chromosomes are the beads. There are two strands of DNA that intertwine forming a pattern called the "Double Helix"

basically, a gene is part of a chromosome. which all falls underneath DNA"

To my understanding, a chromosome consists of a single DNA string (up to 2 meters long if unfolded) that is tightly curled up around many protein molecules (histone) and around itself (much like old telephone wires after years of use). The resulting bundle is called a chromosome.

A Gene is a particular section of the chromosome's DNA string. There are many such sections on the DNA string - thus it contains (also calls 'codes') many genes - in humans between 500 and 4500 depending on what chromosome. One gene contains information for producing one particular protein. It is the sequence of bases (T, C, G or A) in the DNA gene section that defines which protein.

The beginning and end of a gene section is marked by a start and a stop sequence ( also called codons) of a gene. In DNA the start can typically be the base sequence ATG and the stop sequence typically TAA, TGA or TAG.

Humans have 23 pairs of chromosomes. Each chromosome has a different DNA string. Thus some times you see people wrinting that a chromosome is only a part of a person's DNA. By that, they mean all the DNA in the body - whcih of course is true, since you have 23 different pairs of chromosomes. But that should not be misunderstood as "a chromosome is part of a DNA string" as frequently seen on the net.
Genes are to be found on Chromosomes.

And Chromosomes are singular pieces of DNA, which contain many genes, regulatory elements and other nucleotide sequences.

What is the relationship between chromosomes and genes and between genes and DNA?

Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.


What best expresses the relationship between genes and DNA?

Genes are segments of DNA that contain instructions to make proteins. DNA serves as the genetic material carrying the genetic information that determines an organism's traits through the expression of genes. Genes are the functional units of DNA, carrying out specific functions in the cell.


What are the links between DNA genes chromosomes and proteins?

Chromosomes are long strands of DNA which are held together by proteins.


What is a sentence explaining the relationship between DNA genes and chromesones?

DNA is the hereditary material that contains genes, which are specific sequences of nucleotides that code for proteins and determine traits. Chromosomes are structures within cells that organize and package DNA, with each chromosome containing many genes. In essence, genes are segments of DNA located on chromosomes, and together they play a crucial role in genetics and inheritance.


What is the difference between a chromosome and a DNA molecule?

The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.

What is the difference between DNA genes chromosomes?

Genes are basic units of Inheritance and are the templates for the creation of proteins, whereas Chromosomes are the molecular structures within the nucleus that contain genes.


What is the difference between chromosomes and genes?

Chromosomes are structures within cells that contain DNA, while genes are specific segments of DNA that provide instructions for a particular trait. Chromosomes house many genes, along with other DNA sequences, and are inherited in pairs, one from each parent. Genes determine specific traits, such as eye color or blood type.


How does DNA show relationships between organisms?

it shows genes and different genes


What is the difference between intergenic and intragenic regions in a genome?

Intergenic regions are stretches of DNA located between genes, while intragenic regions are parts of a gene itself.


Are genes in DNA or are DNA in geans?

genes are in DNA

What is the relationship between genes and proteins?

DNA Genes and Proteinthe gene is a subunit of DNA, one strand of DNA is copied into mRNA which is then translated into proteins


What is the difference between recombination and transformation?

Recombinants take up the plasmid but do not incorporate it into the DNA. Transformants take up the plasmid and integrate it into the DNA. Recombinants wouldn't express the new genes while Transformants will.


What is the difference between Cells and Genes?

Cells are the basic structural and functional units of living organisms, containing all the necessary components for life. Genes, on the other hand, are segments of DNA that contain instructions for building proteins and determining traits. Genes are found within cells and are passed down from parents to offspring.


What is the differences between a chromosome and a DNA molecules?

Somewhat the difference between a brick and a brick wall. Chromosomes are made up of DNA molecules collected in units called genes ( leaving all else aside ) with attendant proteins, such as the histone proteins DNA wraps around.


Difference between chromosomes and genes?

Chromosomes are structures that contain genes, which are the functional units of heredity. Genes are specific segments of DNA that encode information for producing proteins, while chromosomes are made up of DNA and protein and contain many genes. Chromosomes are organized in pairs in a cell's nucleus, while genes are the specific units on chromosomes responsible for inherited traits.
