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. WebThe archaeal proteins are smaller (320–330 residues) than their eukaryotic counterparts (410–450 residues). They have been isolated and shown to have primer synthesis …
