What are the two structures that all viruses have in common?
RNA (Ribo-nucleic Acid) and a Protein coat called the capsid.
Is viruses a producer or consumer?
Neither - viruses do not eat. There are debates about whether viruses are a form of life, or organic structures that interact with living organisms.
What structures are found in all viruses?
All viruses contain genetic material (DNA or RNA) and a protein coat (capsid) that surrounds and protects the genetic material. Some viruses also have an outer lipid envelope that is derived from the host cell membrane.
Are viruses living structures based on the 7 properties of life?
Viruses are not considered living structures because they do not exhibit all the properties of life. While they can replicate and evolve, they lack the ability to carry out metabolic processes, respond to stimuli, or maintain homeostasis independently. Viruses rely on host cells to reproduce, making them dependent entities.
What structures do viruses have that allow them to identify a specific type of cell and attach to it?
good
Do viruses have endospores?
No, viruses do not have endospores. Endospores are a dormant form of certain bacteria that allow them to survive harsh conditions, while viruses lack the cellular machinery to form such structures. Viruses are much simpler entities compared to bacteria.
Why growing or cultivation of viruses is of medical importance?
-to isolate and identify viruses in clinical specimens -prepare viruses for vaccines -to research in detail the viral structures, multiplication cycles, genetics, and effects on the host cells
Does viruses have chloroplasts?
No, viruses do not have chloroplasts. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. Viruses are not living organisms and do not have cellular structures like chloroplasts.
Does a virus have hyphae?
No, viruses do not have hyphae. Hyphae are branching, thread-like structures that make up the body (mycelium) of fungi. Viruses are a different type of microorganism that are not composed of cells and do not have structures like hyphae.
What is the structure of a virus like?
Viruses are ranges in different sizes and structures. HIV, HBV, influenza are all spherical in shape. Phages like T phages carry an icosahedral structures. M13 phages, ebola appear as hair like (or tube) structures. TMV appears as rod like structure.
Do virus have starch granules?
No, viruses do not have starch granules. Starch granules are complex carbohydrate structures typically found in plants and some algae, used for energy storage. Viruses are simpler entities that lack the cellular machinery necessary to produce or store such structures.
Can viruses reproduce by themselves?
No. Viruses must invade a host cell and hijack its resources to replicate itself.
