Cell nucleus

Cell nucleus
In cell biology, the nucleus (from Latin nucleus or nuculeus, kernel) is an organelle, found in the majority of eukaryotic cells, which contains most of the cell's genetic material.

Cell nucleus (a cell's information center)
The cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis occur.

Structure in a cell nucleus that carries the genes. Each chromosome consists of one very long strand of DNA, coiled and folded to produce a compact body. They become more compact and visible during metaphase of cell division.

caption: In the cell nucleus, RNA is produced by transcription, in much the same way that DNA replicates itself. RNA, however, substitutes the sugar ribose for deoxyribose and the base uracil for thymine, and is usually single-stranded.

aren't five kingdoms of life, we know-and it's very well established-that there are three domains of life, the bacteria, the archaea, and the eukaryotes. The bacteria and the archaea are the prokaryotes. They're both organisms without a cell nucleus.
