Why retro virus is RNA virus?
Because retro virus has only RNA as genetic material. Its replication is in reversal order known as Reverse Transcriptase.
Which virus is transcribed from RNA to DNA to RNA during the replication cycle?
The general class of these viruses is retrovirus.
Why rna virus is more mutant than dna virus?
during replication RNA-polimeraze it make a lot of erros.In this ways RNA viruses it mutate faster than DNa viruses.
How is retrovirus different from DNA virus?
Retro virus has reverse transcription in its replication cycle. In other words, rna is template for synthesis of dna. With dna virus, there is no reverse transcription in the replication cycle. Dna is the template for dna synthesis.
What nucleic acid does the Ebola virus consist of?
The Ebola virus consists of single-stranded RNA (ssRNA) as its nucleic acid. This RNA is negative-sense, meaning it must be converted into a positive-sense RNA by the viral RNA polymerase before it can be translated into proteins. The viral genome encodes several proteins essential for the virus's replication and pathogenicity.
What may contain DNA or RNA but not both?
Viruses can contain either DNA or RNA, but not both. However, some viruses may have both DNA and RNA at different stages of their replication cycle.
If RNA extracted from a virus was injected into a host cell the cell will not begin to make new viruses.?
If RNA extracted from a virus is injected into a host cell, the cell may begin to produce new viruses, provided the RNA is infectious and the host cell has the necessary machinery to translate and replicate the viral RNA. For many RNA viruses, the injected RNA can serve as a template for translation into viral proteins and for replication of new viral genomes. However, if the RNA is non-infectious or lacks necessary elements for translation and replication, the host cell will not produce new viruses.
What is the method of action of nucleoside analogs?
Nucleoside analogs interfere with viral replication by being incorporated into viral DNA or RNA during replication, which disrupts the normal functioning of the virus. This disruption prevents the virus from replicating efficiently and ultimately leads to its inhibition.
Viroids differ from viruses by what?
Viroids differ from viruses in that they are composed of a single-stranded circular RNA without a protein coat, while viruses have genetic material made of DNA or RNA enclosed in a protein coat. Viroids also do not encode proteins, relying on host enzymes for replication, whereas viruses typically encode proteins that contribute to their replication.
What enzyme manufactures DNA that is complementary to a virus's RNA?
The enzyme that manufactures DNA complementary to the virus's RNA is called reverse transcriptase. Reverse transcriptase converts the viral RNA into DNA, which can then be integrated into the host cell's genome. This process is a key step in the replication cycle of retroviruses like HIV.
Is yellow fever virus DNA or RNA?
Yellow fever is a single stranded RNA virus (ssRNA)
Does rabies virus contain RNA or DNA?
Rabies virus is a RNA virus, specifically a negative-sense single-stranded RNA virus.
