Domain archaea does not contain introns

WebWhich is true regarding genomes of Archaea? a. Archaeal genomes are generally larger than those of Bacteria. b. Unlike Bacteria, Archaea do not show a strong correlation between genome size and ORF content. c. Archaea have fewer genes for carbohydrate metabolism, transport, and membrane biosynthesis. d. WebIntrons are rare in Bacteria and Archaea (prokaryotes), but most eukaryotic genes contain multiple splicesomal introns. Discovery and etymology [ edit ] Introns were first discovered in protein-coding genes of adenovirus , [4] [5] and were subsequently identified in genes encoding transfer RNA and ribosomal RNA genes.

WebJan 12, 2024 · Archaea is a group of primitive prokaryotes that based on their distinct characteristics form a separate domain from bacteria and eukaryotes. The term ‘Archaea’ is derived from a Greek word, ‘archaios’ which means primitive or ancient, indicating the primitive structure of these organisms. WebJun 7, 2012 · But, it does not contain introns and repetitive sequences. Furthermore, prokaryotic genes exist as clusters that regulate by a single promoter. And also, this single chromosome is circular and touches with the cell membrane from some points. Structurally, prokaryotic genome is more compact than eukaryotic genome. guna helminth https://triplebengineering.com
