chromosomes
Chromozome
Chromosomes, which are made of DNA and proteins, hold hereditary information in the cell's nucleus. DNA contains the genetic instructions that determine an organism's traits.
The hereditary information of the individual is held in the nucleus. The nucleus is what holds the chromosomes which contain genes.
DNA
Chromosomes, specifically the DNA molecules wrapped around proteins called histones, hold the genetic information in a cell's nucleus. This genetic information contains the instructions for cellular processes and heredity.
chromatin or chromosomes
DNA
The nucleus holds the genetic information of a cell.
The nucleus holds DNA, which is the chemical makeup of the cell.
The nuclear envelope, also known as the nuclear membrane, surrounds and holds together the nucleus in eukaryotic cells. This double-membrane structure helps control the movement of molecules in and out of the nucleus.
An organism's hereditary information is held in its DNA (deoxyribonucleic acid), which is a molecule that contains the genetic instructions for development, functioning, growth, and reproduction. DNA is organized into structures called chromosomes, which are located in the nucleus of cells.
In cells they are in DNA. In virus they are in DNA or RNA
