RNA processing in prokaryotic cells

BioEssays, 1993
AbstractRNA processing in Escherichia coli and some of its phages is reviewed here, with primary emphasis on rRNA and tRNA processing. Three enzymes, RNase III, RNase E and RNase P are responsible for most of the primary endonucleolytic RNA processing events. The first two are proteins, while RNase P is a ribozyme.

Magnetic Inclusions in Prokaryotic Cells

Microbiology, 2003
Prokaryotic cells may contain one of two types of magnetic intracellular structures, either crystalline magnetosomes or noncrystalline magnetic inclusions. In a magnetic field, the locomotor behavior of cells containing magnetosomes is categorized as magnetotaxis, whereas noncrystalline magnetic inclusions cause a passive attraction of cells containing

Functional Inclusions in Prokaryotic Cells

International Review of Cytology, 1988
Publisher Summary This chapter reviews the functional inclusions in prokaryotic cells. Inclusions are visible expressions of cell metabolism. The inclusion is an integral part of the cell's metabolic machinery, it is important in adjusting the environment of the cell, thereby regulating certain metabolic events, or might represent a product of the ...

Single-cell model of prokaryotic cell cycle

Journal of Theoretical Biology, 2014
One of the recognized prokaryotic cell cycle theories is Cooper-Helmstetter (CH) theory which relates start of DNA replication to particular (initiation) cell mass, cell growth and division. Different aspects of this theory have been extensively studied in the past. In the present study CH theory was applied at single cell level.

Prokaryotic Cell Structure and Function

2021
Prokaryotes are single-celled organisms comprising of bacteria and archaea. The cells have different morphologies that vary in shape, size and arrangement as well as there are certain structural differences varying from organism to organism. The internal structure of a prokaryotic cell has been studied in great details which became possible due to ...

Programmed Cell Death in Prokaryotes

Critical Reviews in Microbiology, 1997
Programmed cell death (PCD), also referred to as apoptosis, is a cellular "suicide" mechanism, based on information from its own internal metabolism, environment, developmental history, and genome. This system was described in eukaryotes continuously along evolution, through amoebae, nematodes, insects, and animals.

Comparative Biology of Prokaryotic Resting Cells

1973
Publisher Summary This chapter examines the comparison of the properties of various types of resting cells formed by prokaryotes. It also describes the formation of the resting stage, the resting cell, and the germination. The chapter largely emphasizes on the comparative aspects of resting cells.

Prokaryotic Cell–Cell Interaction

2010
Cell wall components are used by many microorganisms for interactions with and within their habitat. A few examples of interactions between microbial cells are described here, covering the biological system and the cell surface components used for these interactions.

Characteristics of Prokaryotic and Eukaryotic Cells

2022
This chapter explains the characteristics of prokaryotic and eukaryotic cells. It starts by looking at the diversity of cells before moving on to talk about the characteristics of the Bacteria and Archaea. Cells were first identified through the phospholipid membrane, which is common to all life.

Cell Division in Prokaryotes and Eukaryotes

2022
This chapter discusses cell division in prokaryotes and eukaryotes. Life on Earth depends on cell division and the transfer of genetic information which triggers the propagation and evolution of species. Unlike the reproduction of eukaryotes, prokaryotes adopt asexual reproduction strategies such as binary fission, budding, or fragmentation.
