Is DNA and genes the same in Biology?
I have read a couple of books and these are not clear to.
I know only one thing - that is that I know nothing.

To put it simple: your genes are part of your DNA.
In the beginning there was nothing, which exploded.

It would be polite to say thankyou to the person or people who answered your previous questions, as you post another one. Otherwise people will start to think either you don't read the answers, or you don't thank people who make an effort to help you. Just some friendly advice...

Hope can halp.
DNA (deoxyribonucleic acid) carries the genetic information in the body’s cells.
A gene is a distinct portion of a cell’s DNA. Genes are coded instructions for making everything the body needs, especially proteins.
So, gene is part of DNA.

DNA- Deoxyribonucleic Acid..DNA is the chemical component of chromosomes,which are located in the nucleus of every cell.Stretches of DNA code for genes.
Gens-a segment of DNA that codes for a protein,which in turn codes for a trait(skin color,tone,eyes...etc),a gene is a stretch of DNA..
so genes are part of DNA..

I have read a couple of books and these are not clear to. DNA is the structure that supports genes. It is the stuff that genes are made of. Genes and alleles are expressed in different forms of DNA, but they are not identical.

Genes contain DNA (deoxyribonucleic acid). DNA is the chemical basis of heredity. Think of it this way: DNA is in genes, genes are on chromosomes. When "mapping" all genes on all human chromosomes was first seriously conceived, it was called the Human Genome Project - a combination of gene and chromosome.

The following illustration explains all.  The black figure is that of a DNA. The pink line is elongated DNA with genes on it . Source: Wikipedia.

I don't agree with that at all. There is no such thing as " a DNA". DNA is an uncountable noun - it is a chemical, like "water" or "salt" or "sugar". Chromosomes are made up of genes. You can have " a gene". Genes are made of DNA. That image (I can't find the original in Wiki - can you post a link?) seems to show a chromosome - like this image.  Consider a bag of lollipops. The full bag with all the lollipops is like a chromosome. One lollipop is like a gene. "Sugar" is like "DNA".

Thanks DragO sir for correcting my grammar. And here is the link you asked for; https://en.wikipedia.org/wiki/Gene

Thank you!
What a strange image - when I see it (the original in Wiki) it has all the parts labelled, but when I copy it, all the words disappear!
