The type of cells that have DNA inside a nucleus are called eukaryotic cells. These cells are characterized by the presence of a membrane-bound nucleus, which contains the cell’s genetic material.
In contrast to prokaryotic cells, like bacteria, which do not have a nucleus and their DNA floats freely in the cytoplasm, eukaryotic cells organize their genetic material within the nucleus. This organization allows for more complex regulation of gene expression and greater protection of the DNA.
Eukaryotic cells can be found in various organisms, including plants, animals, fungi, and protists. For instance, human cells, which are eukaryotic, have multiple linear chromosomes stored within the nucleus. This structure plays a crucial role in cell division, DNA replication, and overall cellular function.
