What does a cell nucleus contain?

DNA molecule, biology

A cell nucleus is a membrane enclosed organelle found in eukaryotic cells. Nucleus contains all of the genetic information a cell has, in the form of DNA. It also contains various proteins. For example proteins, histones, are what DNA strands wrap around to form chromosomes. Furthermore, both DNA replication as well as transcription happens in the nucleus. Transcription is the process of creating RNA from DNA template. Thus, RNA is also found in the nucleus. After it is formed, it oftentimes, gets modified and then goes outside of nucleus through the nuclear pores. RNA, can then start translation (process of creation of proteins from RNA template).
