Verified step by step guidance1
Understand that genes are segments of DNA that contain the instructions for building proteins and are crucial for the functioning of living organisms.
Recognize that the primary location of genes in eukaryotic cells is within the nucleus, where the majority of the cell's genetic material is organized into chromosomes.
Acknowledge that genes are also found in mitochondria, which have their own small circular DNA, known as mitochondrial DNA, inherited maternally.
Note that the cytoplasm does not contain genes, but it is the site where protein synthesis occurs, using the genetic instructions transcribed from nuclear DNA.
Clarify that the cell membrane does not contain genes; it functions as a barrier and communication interface for the cell.
