This chunk became the, Gene expression is the ability of a gene to produce a biologically active protein. The largest subunit is called the 60-s (svedberg - unit of measurement for time) and the smallest as the 40-s. All cells share certain structural and functional features and they
The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life. However, unlike an animal cell, plant cell membranes have an extra enclosure called a cell wall. The Origin of Eukaryotic Cells A major difference is the presence in eukaryotes of a nuclear membrane, which prevents the simultaneous transcription and translation that occurs in prokaryotes. These two observations are not unrelated to each other.
Eukaryotic cells have a true nucleus, bound by a double membrane. The characteristics of living cells are: Introduction
