It's been around since God created Earth.
chromatin
DNA coils around proteins called histones.
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.
Yes. Chromosomes are DNA that have been wound around histones to form nucleosomes. The nucleosomes that have condensed are what forms the complete chromosomes.
Telescopes have been around since before the 1500's.
The average human DNA, if stretched out, would be about 3 meters long. Not quite long enough to stretch around the earth.
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.
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.

how long has deforestation been around
As long as guns have been around.
Real time PCR has been around for over twenty five years. It was revolutionized in the mid 1980's. Real time PCR helps view how much is increased in a DNA sample.
