It's been around since God created Earth.
It is called DNA supercoiling. This coiling helps to compact the long strands of DNA into the small space inside a cell.
DNA coils around proteins called histones.
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.
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 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.
It is called DNA supercoiling. This coiling helps to compact the long strands of DNA into the small space inside a cell.
how long has deforestation been around
As long as guns have been around.
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 the london eye been around for
As long as So Random has been around.
DNA coils around proteins called histones.
