Sentences with phrase «not eukaryotes»

Not all eukaryotes harbor the classical aerobic mitochondria.

Though newly discovered Asgard group are not eukaryotes, they share some important similarities — including genes that were thought to exist only in complex cells.

Cyanobacteria are relatives of the bacteria, not eukaryotes, and it is only the chloroplast in eukaryotic algae to which the cyanobacteria are related.

Not exact matches

We evolved from other eukaryotes, but eukaryotes do not automatically evolve to be humans.

If you are still contemplating your first encounter with these little eukaryotes, then, fear not... just grab yourself a refrigerated pizza or bread dough from the store!

Although some amoebas presumably can not have sex and divide by mitosis, others are among the eukaryotes that can have sex — a process that can most simply be defined as ripping a genome in half and later recombining it.

But the way archaea DNA twists around histones isn't identical to the coils of DNA seen in eukaryotes.

«So it's not as uniform as in eukaryotes,» says coauthor Karolin Luger, a biophysicist and Howard Hughes Medical Institute investigator at the University of Colorado Boulder.

«It doesn't really matter which eukaryote you look at, whether it's amoebas or plants or humans or fish or insects or anything,» says coauthor John Reeve, a microbiologist at Ohio State University.

The advent of the nucleus — which differentiates eukaryotes (organisms whose cells contain a true nucleus), including humans, from prokaryotes, such as bacteria — can not be satisfactorily explained solely by the gradual adaptation of prokaryotic cells until they became eukaryotic.

Unlike bacteria, some archaea also contain histones, but researchers weren't sure whether these microbes spool DNA around the protein bobbins the way eukaryotes do.

I would be surprised if such eukaryotes did not date back to at least 3.0 billion years before the present.

In particular, one of the enzymes needed for the synthesis of important glycoconjugates had not yet been identified: the apicomplexan organisms do not have the GNA1 enzyme that fulfils this function in animals, plants and other eukaryotes.

Most biologists typically recognize three official branches of life: the eukaryotes, which are organisms whose cells have a nucleus; bacteria, the single - celled organisms that may or may not possess a nucleus; and archaea, an ancient line of microbes without nuclei that may make up as much as a third of all life on Earth (See «Will the Methane Bubble Burst?»

The researchers predict that, when Loki is finally isolated or cultured, «it will look more like an archaeon than a proto - eukaryote and will not have internal compartments or a vesicle - trafficking network.»

Yeasts, like humans, are eukaryotes: They have complex DNA packaged in chromosomes and riddled with introns (pieces of DNA that don't contribute to the final protein) and «junk DNA» with no known purpose.

Mitochondria provide energy for most eukaryotes, but not for a new microbe living in the guts of a chinchilla.

It became clear that the history of all eukaryotes can not be reconstructed in any sensible tree based on one gene.

He notes that this adds to a long line of studies showing that bacteria are more and more similar to eukaryotes and are not just «bags of enzymes.»

«We're still not very good at predicting genes in eukaryotes,» said Claire Fraser of The Institute for Genomic Research in Rockville, Maryland.

The reason for the disparity may be that the standard computer annotation method was largely developed for the genomes of simple (prokaryotic) organisms, not for the more complex sequences found in the genomes of humans and other eukaryotes.

This discovery means there are not two lines of descent of life but three: the archaebacteria, the true bacteria and the eukaryotes

A green alga with throat - and stomach - like structures can swallow and digest bacteria when deprived of light, further bolstering Lynn Margulis's widely accepted idea that the origin of the plant - powering chloroplast was a fortuitous bout of indigestion.Termed «Endosymbiotic Theory», the idea is that early nucleated cells called eukaryotes ate bacteria that managed to escape digestion but also couldn't escape their captors.

$ 2,500 «Beyond bacteria» Deeper shotgun metagenome and virome characterization of one sample, plus additional marker gene sequencing (16S rRNA, 18S rRNA and ITS, for you sequencing wonks) to characterize not just the bacteria but also the viruses, microbial eukaryotes (like giardia), and fungi in your gut.

In eukaryote organisms (almost all large organisms, such as animals, plants, and fungi, but not bacteria), DNA forms a complex with proteins that are called histones.

These were the eukaryotes — mainly plants and animals, whose cells had a nucleus — and the prokaryotes, such as bacteria, whose cells did not.

Our results imply that the genomes of haplodiploid and of diploid higher eukaryotes do not differ systematically in their recombination rates and associated parameters.

With the sequencing and annotation of genomes and transcriptomes of several eukaryotes, the importance of noncoding RNA (ncRNA)- RNA molecules that are not translated to protein products - has become more evident.

Not just bacteria, but also Archaea, Eukaryotes, and Viruses — and all down to the species and strain level.»

I'm not really sure what a genome is, let alone terms like «electrophoresis» or «eukaryotes.»
