What represents a difference between viruses and viroids?
Viroids are plant pathogens that consist of a short stretch (a few hundred nucleobases) of highly complementary, circular, single-stranded RNA wthout the protein coat that is typical for viruses. The smallest discovered is a 220 nucleobase scRNA (small cytoplasmic RNA) associated with the rice yellow mottle sobemovirus (RYMV). In comparison, the genome of the smallest known viruses capable of causing an infection by themselves are around 2 kilobases in size. The human pathogen hepatitis D issimilar to viroids.A virus is a small infectious agentthat can replicate only inside the living cells of organisms. Viruses infect all types of organisms, from animals and plants to bacteria and archaea.
Can you see a viroids pathogen in a light microscope?
Viroids are smaller than viruses and cannot be seen using a light microscope as they lack a protein coat. They are typically detected using molecular techniques like PCR.
Infectious naked strands of RNA are called?
Infectious naked strands of RNA are called viroids. Viroids are small, circular pieces of RNA that can infect plants and disrupt their normal growth and development.
What is a infectious agent composed of a simple strand of RNA with no protein component?
A infectious agent composed of a simple strand of RNA with no protein component is called a viroid. Viroids are smaller and simpler than viruses, consisting only of a short, circular RNA molecule. They can infect plants and disrupt their normal growth processes.
Do all viruses have an envelope?
No. I don't think so.
Which is the smallest virus infecting human beings?
The human rhinovirus, the virus that causes common colds, is the smallest human-infecting virus, with an average diameter of about 30 nanometers. Other viruses such as smallpox are around 10 times larger, at 300 nanometers.
Describe the 4 kingdoms that comprise the domain prokarya?
The domain Prokarya consists of the kingdoms Bacteria, Archaea, Viruses, and viroids. Bacteria and Archaea are single-celled organisms with prokaryotic cells, while viruses and viroids are acellular infectious particles. Bacteria are diverse and found in various environments, while Archaea are often extremophiles. Viruses and viroids are not considered living organisms and require a host for replication.
How do viroids and prions compare with viruses?
Viroids are small infectious agents consisting of a short, single-stranded RNA molecule, while prions are misfolded proteins without nucleic acid. In contrast, viruses are composed of genetic material (DNA or RNA) surrounded by a protein coat. Viroids and prions lack the ability to replicate independently, unlike viruses which require a host cell for replication.

What kinds of microbes are there?
I) Prions II) Viroids III) Viruses IV) Archaebacteria V) Eubacteria, and VI) The Protists.
Is the smallest living organism?
I think currently the smallest living organisms are thought to be "viroids", which are smaller than viruses. Scientists are still figuring out exactly what viroids are, and do, but they are able to replicate, which means they are life.
Can you see a viroids pathogen in a light microscope?
Viroids are smaller than viruses and cannot be seen using a light microscope as they lack a protein coat. They are typically detected using molecular techniques like PCR.
What are 2 non-living pathogens?
Viruses and prions are examples of non-living pathogens. Viruses require host cells to replicate, while prions are misfolded proteins that can cause disease by inducing other proteins to misfold.
What basic structure do viruses share?
Unlike prions and viroids, viruses consist of two or three parts: all viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Viroids do not have a protein coat and prions contain no RNA or DNA. In short, just say that all viruses have a protein coat and either DNA or RNA.
How are viroids and prions the same?
Both Viroids and Prions have nucleic acid, but Viroids have no outer protein coat.
Why is so little known about viroids?
Why is so little known about viroids
How are bacteria unlike virusesviroidsor prion?
Bacteria are single-celled prokaryotic organisms that can reproduce independently and have cellular structures, including a cell wall and metabolic machinery. In contrast, viruses, viroids, and prions are acellular entities; viruses require a host cell to replicate, viroids consist of short RNA strands without a protein coat, and prions are misfolded proteins that induce misfolding in normal proteins. Additionally, bacteria can carry out metabolic processes and respond to stimuli, while viruses and prions do not exhibit metabolic activity.
