It wraps around histones and coils into a fiber
Acetylation is the compacting of a DNA molecule, making it more compact and reduces its ability to be transcribed.
True. Before DNA can replicate itself, it must condense and coil up on itself to form more compact structures called chromosomes. This compactness helps to organize the genetic material and ensure that it is efficiently replicated during cell division.
DNA can compact itself through a process called DNA condensation, where it wraps around proteins called histones to form structures called nucleosomes. These nucleosomes then coil and fold into higher-order structures, ultimately leading to the highly compacted form known as chromatin. This compaction allows the long strands of DNA to fit within the nucleus of a cell.
Supercoiling of DNA helps to compact the long DNA molecule into a smaller space within the cell. This compact form makes it easier to fit inside the cell's nucleus and helps regulate gene expression by affecting the physical accessibility of the DNA. Supercoiling also plays a role in DNA replication and gene regulation.
It is more compact and is protected against certains types of damage.
they break apart and they find other DNA strands and form more DNA strands.

DNA replication
DNA arranges itself into a double helix.
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.
The universal DNA code can make a copy of itself.
The DNA code that can move itself into the cytoplasm is ribosomes.
