Web6 de dez. de 2024 · December 6, 2024 by Brianna. Eukaryotic cells are able to regulate gene expression by controlling the proteins that are produced from those genes. They do this by controlling the activity of the enzymes that are responsible for translating the genetic information contained in the DNA into proteins. By controlling the activity of these … WebAlexa Jacob. The Endoplasmic Reticulum in a eukaryotic cell is the transport network of the cell and it extends from and connects the nuclear membrane to the plasma membrane of a cell. But then whenever we draw a diagram of a typical plant or animal cell, we never extend it to the plasma membrane- we always leave it somewhere in the cytoplasm.
