Each chromosome has a single strand of DNA.
chromatin
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
DNA strands.
The structures are called chromosomes.
The nucleus contains chromosomes which contain strands of DNA.
In a cell, the tangles of long strands of DNA form the
chromosomes
Chromosomes are long strands of DNA which are held together by proteins.
Strands of DNA are bundled into structures called chromosomes in a cell. Chromosomes are made up of DNA wrapped around proteins called histones, and they contain the genetic information needed for cellular functions.
In chromosomes which are stored in DNA strands.
