Answer the following 2
questions using complete sentences: what type of cells contain dna? which cells in the human body have chromosomes?

The cell containing DNA is known as the nucleus. Chromosomes are located in the nucleus of every cell.

1) Eukaryotic cells are cells which contain a nucleus and organelles, and are packed up by a plasma membrane. Examples of organisms that have eukaryotic cells are protozoa, fungi, plants and animals. All of these types of cells contain DNA.Genes are composed of DNA, and it is predicted that there are over 3 billion basepairs in the human genome.
