Are there introns in prokaryotic genes? Does ribosomal RNA have introns? Do prokaryotes have exons? What are introns and what are exons? a) Introns are noncoding regions of DNA and exons are coding regions of DNA. Do archea have introns?
Why do Eukaryotes have so much more non-coding DNA than Prokaryotes? In eukaryotic cells, how are genes that are needed together made active at the same time? Like eukaryotes, bacteria and archaea enclose their DNA in a nucleus. True or false? Explain. How many types of RNA and DNA are...
Prokaryotes, on the other hand, are single-celled organisms such as bacteria and archaea. ... They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus,prokaryotes have no mitochondria...
In prokaryotes, transfer of DNA from a donor cell to a recipient cell is mediated by direct cell–cell contact. CONSPECIFICS Members of the same species. FITNESS A measure of the capacity of an organism to survive and reproduce. HOLLIDAY JUNCTIONS Cross-shaped junctions at which four strands of...
To answer the question why eukaryotic cells release vesicles, we may learn from prokaryotes. Bacteria release outer membrane vesicles, resembling microparticles, which act as “multi-purpose carriers”. They contain signalling molecules for other bacteria, deliver toxins to host cells and exchange DNA ...
Answer and Explanation:1 There are several genes which help the brain-eating amoeba (Naegleria fowleri)do its functions. Naegleria fowleri is a eukaryotic pathogen which... Learn more about this topic: Virulence Factor | Definition, Examples & Bacteria ...
Although the International Committee of Systematics of Prokaryotes supports the taxonomy that is described above, it is not used consistently in the literature. Readers may therefore come across a compromised taxonomy that many chlamydial researchers have adopted, which eliminates the genus Chlamydophila...
As the evolutionary story is usually told,first came the prokaryotes: the archaea and bacteria, which are often envisioned as simple bags of enzymes without an intricate structure. Which is true of Archaea? Which is true of archaea?They contain many documented human pathogens. They have unique ...

Why are inclusion bodies encapsulated in prokaryotes? Why are the cells in the stratum corneum dead? Why does cellular respiration occur? Why is cellular respiration important to the biosphere? Why do bacteria show characteristic cellular shapes and arrangements?
