What structure carries genetic information in eukaryotic cells?

The structure that carries genetic information in eukaryotic cells is the nucleus. The nucleus is often referred to as the control center of the cell, as it houses the cell's DNA, which contains the instructions necessary for the development, functioning, growth, and reproduction of the organism. The DNA is organized into chromosomes within the nucleus, and during cell division, these chromosomes ensure that genetic information is accurately passed on to daughter cells.

In contrast, while mitochondria do contain their own DNA, their primary role is in energy production through cellular respiration. Ribosomes are responsible for protein synthesis, translating the genetic code into proteins but do not store genetic information. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell, but it also does not contain genetic material. Thus, the nucleus remains the central structure for storing and managing genetic information in eukaryotic cells.
