What do viruses have to rely on for replication?
They rely on their host. They can not reproduce on their own, so they are not considered living. They inject genetic information into a host cell and make the cell produce more viruses.
The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is?
The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is the injection of only the viral nucleic acid into the host cell. Viruses that infect bacteria are specifically called bacteriophages.
What are the 3 rules that DNA replication must follow?
DNA cannot replicate de novo (i.e. there must be a free 3' OH group to attach nucleotides to) Replication must go from 5' to 3' The two strands of DNA are antiparallel Complementary base pairing
What must occur before replication can begin?
The replication of DNA occurs whenever the cell needs the S shape division. This happens since when we divide, enough DNA is needed to be pass on to our daughters.
What organisms do not grow or show any nutritional patterns and have no observable activity except replication which can be accomplished in the cytoplasm of a living cell?
Viruses, but they are not organisms because they are not alive.
What do viruses have to rely on for replication?
They rely on their host. They can not reproduce on their own, so they are not considered living. They inject genetic information into a host cell and make the cell produce more viruses.
What do viruses do with their DNA?
viruses do replication with their DND
What are properties of viruses?
viruses are non cellular , they have no sexual or asexual reproduction they reproduce by replication
What cells do the cell theory apply to?
plants and animalsmulticellular organisms fungi
Viruses must rely on the -- for reproduction?
host cell (and its machinery for protein synthesis, and it's enzymes for the metabolic processes required)
What is a virus replication that includes the lysogenic cycle?
temperate viruses
Both viruses and cells are able to replicate their genetic material What is the main difference in their replication processes?
Viruses require host cells, whereas cells provide their own replication mechanisms.
What is viral replication?
Viral replication is the process of creating viruses. This can only occur once a virus has infected a cell - because viruses cannot replicate by themselves (they need to use a host cell).
What is need for viruses to grow?
They need a living cell. It is essential for replication.
Do viruses move independently or dependently?
Some viruses can move parts of their body, but most viruses rely on their hosts.
Is HIV able to make copies of itself without the aid of another organism?
No HIV, like all viruses lacks the machinery for self replication. Viruses instead must infect a host cell and hijack the cell to make more viruses. In the case of HIV, it must infect a living human cell in order to copy itself.
What is exogenous virus?
I believe, exogenous virus exist as: "replication competent viruses that are transmitted horizontally in mice, while endogenous viruses exist as germline sequences that are usually not replication competent by may recombine with exogenous viruses during the course of infection." This would refer to exogenous retroviruses.
