In news:

Prokaryotic symbionts are common in invertebrates and play an essential metabolic role in deep-sea hydrothermal vent communities.
This basic difference in how prokaryotes and eukaryotes function allows for the isolation of natural products or development of new materials that inhibit the growth of prokaryotes, yet have no toxic effects on eukaryotes .
A cross-section of a prokaryotic cell, as depicted in the upcoming scientific journal Invisible Monsters: Man's Struggle Against a Miniature Nemesis.
Whatever the case, the interim "B" might be a prokaryote version of the proposed Oakland Streetcar Project, which would run all the way from Jack London Square to Piedmont Avenue, near Kaiser Hospital.

In science:

Multiple coding regions in prokaryotic translation (Shine-Dalgarno sequences) can be modeled as a sequence of initiation (sinks) and termination (sources) sites.
Ribosome recycling, diffusion, and mRNA loop formation in translational regulation
Though there have been a variety of insights into the combinatorial aspects of transcriptional control, the mechanism of DNA looping as an agent of combinatorial control in both prokaryotes and eukaryotes remains unclear.
Concentration and Length Dependence of DNA Looping in Transcriptional Regulation
In the setting of transcriptional regulation, there are a host of regulatory architectures both in prokaryotes and eukaryotes which require the interaction of sequences on the DNA that are not adjacent [4, 5, 6, 7].

Magnetism, FeS colloids, and Origins of Life
As discussed at length by Zeh et al. (2009), eukaryotic genomes contrary to prokaryotic ones have a very low relative amount of sequences coding for RNA or proteins: non-coding ones cover the vast majority of DNA.

Systematic Approach on Differences in Avian Viral Proteins Based on Carbon Composition
In prokaryotes, such as bacteria, the main DNA is arranged in a single chromosome, which has the shape of a ring.

In contrast to prokaryotic epigenetic switches just mentioned, modeling eukaryotic epigenetic silencing involves studying a spatially extended bistable system.

The surprisingly diverse ways that prokaryotes move.
The hydrodynamics of swimming microorganisms
A computation of the frequency of each trinucleotide in the 3 frames of genes, in a large gene population (protein coding region) of both eukariotes and prokaryotes, has established in 1996 that the distribution of trinucleotides in these frames is not uniform.

Template-directed biopolymerization: tape-copying Turing machines
However, in spite of the gross architectural similarities between the polymerases in prokaryotic and eukaryotic cells, there are significant differences in the primary sequences of these machines.
Template-directed biopolymerization: tape-copying Turing machines
Ribosomes found in nature can be broadly divided into two classes: (i) prokaryotic 70S ribosomes, and (ii) eukaryotic 80S ribosomes; the numbers 70 and 80 refer to their sedimentation rates in the Svedberg (S) units.
