18 мая 2018 г. · We have identified 39 group I introns in a wide range of archaeal phyla, including examples of group I introns and BHB introns in the same host gene.

10 авг. 2023 г. · Yes, introns are there in archaea too, but with a far less frequency than in eukaryotes (as I understand!). Does a prokaryotic genome contain introns? - Quora What are introns, and why is it absent in prokaryotic cells? What is the purpose of introns in eukaryotic genomes ... - Quora Другие результаты с сайта www.quora.com

2 янв. 2002 г. · Introns in protein-coding genes are ubiquitous in eukaryotic cells, but pre-mRNA splicing has yet to be reported in archaeal and its viral genomes.

Until recently, it appeared that archaeal introns were spliced by a process specific to the archaeal domain in which an endoribonuclease cuts a ...

23 нояб. 2024 г. · Post-transcriptional modification is simpler than in eukaryotes, since most archaean genes lack introns, although there are many introns in ...

All known archaeal introns are bulge-helix-bulge (BHB) introns, with the exception of a few group II introns.

The cisternal elements are usually tubular and form tortuous arrays in the peripheral cytoplasm and the juxtanuclear area. These cisternae branch repeatedly.

Introns are found in various tRNA genes in all the three kingdoms of life. Especially, archaeal and eukaryotic genomes are good sources of tRNA introns. Structural Characteristics of... · Appearance of Intron...
