DNA has been around for billions of years, dating back to the earliest forms of life on Earth. It is the genetic material that carries instructions for the development, functioning, growth, and reproduction of all living organisms. The discovery of the structure of DNA was made in 1953 by James Watson and Francis Crick.

What is it called when long strands of DNA are wrapped around themselves?
It is called DNA supercoiling. This coiling helps to compact the long strands of DNA into the small space inside a cell.
What are strands of DNA wound around?
DNA coils around proteins called histones.
Does DNA have chromosomes in it or is it the other way around?
Chromosomes are made up of DNA. DNA wraps around proteins called histones to form structures called nucleosomes, which then coil and condense to create chromosomes. Each chromosome contains a single, long DNA molecule.
What form is when DNA is in long strands prior to coiling?
The form DNA takes when it is in long strands prior to coiling is called chromatin. Chromatin consists of DNA wrapped around proteins called histones, and it is the uncoiled and extended form of DNA that allows for gene expression and replication.
Chromosomes are strands of DNA wrapped around?
Chromosomes are not long strands of DNA. Genes are one form of long strands of DNA, specfied by meny amino acids, which are in turn specified by a codon, or three nucleotide bases. DNA actually coils or wraps around the chromosomes during certain stages of development.

Did Watson and Crick invent DNA?
No. DNA wasn't "invented", it's a naturally occurring substance that's been around about as long as life on Earth has been around. They didn't even "discover" it; by the time they were working on it, it had been known for about 100 years. What they did (with a great deal of largely-unacknowleged-at-the-time help from Rosalind Franklin) was figure out the molecular structure.

How long has guns been around?
As long as guns have been around.
Is DNA made if chromosomes?
No. DNA is what chromosomes are made of. DNA is wound around proteins like thread on a spool, but since DNA is one long"string", the DNA is wound around many protein "spools", all of which are connected by DNA. This string of DNA/protein "thread on spools" is wound around itself, and wound around itself, and wound around itself a lot more, then (after a pretty intricate process) Wala! You have a chromosome.
