The eukaryotic cell’s genetic instructions are housed in the nucleus and carried out by the ribosomes
The nucleus is surrounded by the nuclear envelope, a double membrane perforated by pores.
The inner membrane is lined by the nuclear lamina, a layer of protein filaments that helps to maintain the shape of the nucleus.
Most of the cell’s DNA is located in the nucleus, where it is organized into units called chromosomes, which are made up of chromatin, a complex of DNA and proteins.
The nucleolus, a dense structure visible in the nondividing nucleus, synthesizes ribosomal RNA (rRNA) and combines it with protein to assemble ribosomal subunits, which then pass through nuclear pores to the cytoplasm.
