Viruses (biological)

They are definitely not the same. First of all, there are many other agents that can cause infections (bacteria, protozoa, fungi, prions). Then there is also a difference between a virus and a viral infection, the former being the agent of infection, the latter the process of infection itself.

Viruses can contain either DNA or RNA, but not both. DNA viruses have genetic material made of DNA, while RNA viruses have genetic material made of RNA. Some viruses have single-stranded genetic material, while others have double-stranded genetic material.

The virus uses a capsid; a protein structure.

Bacteria use a peptidoglycan cell wall with one or two cell membranes.

Protazoa use different methods. Some have VSP or VSGs; proteins attached to their cell membranes that protect them. Some do not and only have a cell membrane.

Yes, bacteria are named using binomial nomenclature, which consists of two parts: the genus name and the species name. For example, Escherichia coli is the scientific name for a common bacterium often found in the intestines of humans.

It all depends on the virus. It may be a lytic or a lysogenic infection. In a lytic infection, the virus inserts its DNA into host cell and replicate itself until the cell bursts and releases the new copies to infect other host cells. In a lysogenic infection, the virus inserts its DNA and gains control over the host cell, shutting it down and makes copies of itself like lytic infection, but the host cell does not burst.

Protein synthesis is important for viruses because the virus forces the host cell to make proteins that the cell does not need, but the virus does to repoduce. Protein synthesis is important for cells because the proteins are essential for all cellular activites.

Virology is the branch of science that deals with the study of viruses, including their structure, classification, evolution, and interactions with their hosts. It encompasses various disciplines such as molecular biology, genetics, immunology, and epidemiology to understand the behavior and impact of viruses on living organisms.

Our bodies are constantly regenerating cells. I believe all cells are identical as they begin to grow and at some point in their growth cycle they take on an identity which is mapped out in the cells DNA, so cells all "look" alike and then become a lung cell, a liver cell, a skin cell,... so something triggers the cell to change and grow into a specific type of cell. Cancer results when that cell does not change into the needed cell and instead grows out of control. This can be caused by damage to the cells DNA. We know radiation can damage DNA. It is believed solar radiation from to much sun exposer can result in skin cancer. Most people to not realize radioactive material in tobacco is the cause of smokers getting lung cancer. radiation is only one know cause of cancer, I believe we do not know what causes most cells to become cancerous and not grow normally . Maybe a geneticists could expand on my answer

Viruses lack the ability to carry out essential life processes on their own, such as metabolism, growth, and reproduction. They can only replicate inside a host cell by hijacking the host's cellular machinery. Therefore, viruses are considered to be non-living entities until they infect a living organism.

Viruses are considered parasitic because they require a host cell to replicate and reproduce. They hijack the host cell's machinery to make copies of themselves, which can harm the host cell in the process. This dependence on a host cell for replication is why viruses are often classified as obligate intracellular parasites.

Viruses aren't as "living" as the other three that you mentioned. The only thing viruses have in common with them is that they move. Viruses do not eat, breath, grow, or reproduce. They do reproduce, but not independently.

Instead of taking over the host right away, many viruses go into a dormant stage, which means that they wait for the right time and climate (which could even take over a year, like most symptoms of HIV, for example) to do their job. Also, viruses do not attack until inside the cell wall. From there, the virus sends genetic material into the cell membrane, and the cell immediately goes to work reproducing the virus.

The only reason viruses care to survive is to reproduce, and we don't know why.

The first paragraph should have mainly answered your question, I just wanted to make sure you know the important facts--they help. Please give feedback! Thanks.

Viruses reproduce rapidly by hijacking host cells and utilizing their resources to make copies of themselves. Once inside a host cell, the virus replicates its genetic material and assembles new viral particles. This process can happen quickly, leading to a rapid increase in the number of virus particles in the infected individual.

Red blood cells do not serve as antigen-presenting cells. Antigen-presenting cells include dendritic cells, macrophages, and B cells, which play a crucial role in initiating immune responses by presenting antigens to T cells.

The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.

Bacteriophage is a type of virus that infects bacteria. It uses its protein capsid to inject its genetic material into a bacterial cell and replicate. Pilus is a structure found on bacteria that can be used for conjugation, the transfer of genetic material between bacterial cells.

Influenza virus is neither prokaryotic nor eukaryotic. It is classified as a type of virus, which is considered non-living and contains genetic material (RNA or DNA) surrounded by a protein coat. Viruses are distinct from cellular organisms and do not fit into the categories of prokaryotic or eukaryotic.

phages can range from 50nm to 200nm.This dimension dont favorizied virused to enty intairlly into their host bacteria.Cell wall of bacteria it is composed of peptidoglycan a glicoprotein that it protect bacteria again enviromental stress and agents.For this reason phages have evolved to inject their genome to the host bacteria.

Small pox is a viral disease which have no generic or specific name .

Tail pins in bacteriophages help the virus attach to the host bacterial cell by interacting with specific receptors on the cell surface. Once attached, the tail pins facilitate the injection of the viral genetic material into the host cell for replication.

Influenza is caused by a virus. its straight up a virus...

A host cell for a virus is a cell that the virus can infect and hijack to replicate itself. The virus enters the host cell, takes over its machinery to produce more virus particles, and then spreads to infect other cells.

Human papillomavirus (HPV) is caused by a group of more than 200 related viruses. These viruses are transmitted through intimate skin-to-skin contact and can infect epithelial cells, leading to various types of HPV-related conditions, including warts and cervical cancer.

Bacteria are considered living organisms because they can reproduce, metabolize, and respond to stimuli independently. They have a cellular structure with organelles and can carry out cellular processes. In contrast, viruses are not considered living organisms because they cannot reproduce, metabolize, or respond to stimuli on their own - they require a host cell to replicate and carry out their life cycle.
