A Viroid is similar to a Virus, but is smaller and consists of only a strand of RNA, while a Virus is larger and can have either DNA or RNA strands.

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.
How do viruses and cellular organisms differ?
Viruses are not classified as living, while cellular organisms are. Viruses are essentially a protein case with mRNA inside. Cells are far more complicated.
Infectious naked strands of RNA are called?
Viroids
Are bacteria and viruses living things?
Virioids and Viruses are 'psuedo-living' entities, and cannot truly be called 'living creatures'. To be classified as 'alive', an organism needs to meet several criteria, like the ability to respond to stimuli, grow, develop, reproduce, etc. The only one of these characteristic viruses, viroids and prions share with living creatures, is the ability to repoduce. They are self-replicating pieces of DNA or RNA, sometimes covered with a coat of proteins, and do not show any other characteristics of being a living creature.
Do all viruses have an envelope?
No. I don't think so.
What are 2 non-living pathogens?
viruses and viroids.
How do viroids and prions compare with viruses?
they both doesn't have nucleus Type your answer here...
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.
What is the smallest known life form?
I believe that is what biologists call "viroids", which are much smaller than viruses, and as of yet are not completely understood. but if your asking for the answer for your homework and its not "viroids" its definitely "microbes" your welcome 100% on my tests ;)
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.

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
The only known infectious agents that lack genetic material are A. certain viruses. B. prions. C. viroids. D. none of the above D?
It is B Prions
