How does dna fit into a cell
WebTo make it all fit, the DNA is tightly wound into structures called chromosomes and packaged into a membrane-bound compartment in the cell, called the nucleus. Many organisms are diploid, meaning they have two copies of every chromosome-one from their mother and one from their father. WebCellular DNA is never bare and unaccompanied by other proteins. Rather, it always forms a complex with various protein partners that help package it into such a tiny space. This DNA-protein...

WebThe length of a chromosome greatly exceeds the length of the cell, so a chromosome needs to be packaged into a very small space to fit within the cell. For example, the combined length of all of the 3 billion base pairs [1] of DNA of the human genome would measure approximately 2 meters if completely stretched out, and some eukaryotic genomes ...
