nucleus

These non-coding RNAs usually carry out their functions either in the nucleus, where the cell's DNA is located, or in the cytoplasm, where most cellular processes occur.

In the Milky Way, only the central nucleus has star densities remotely comparable, and that region still contains only about one thousandth of the stars needed for the little-red-dot models.

However, the study revealed that HSL also resides inside the nucleus of fat cells.

Isotopes are different versions of the same element that vary only in the number of neutrons in the nucleus and therefore in their mass.

Researchers can also reposition damaged DNA inside the nucleus to test how its location influences repair.
