What else can I help you with?
Is influenza single strand or double strand RNA?
It is single stranded RNA. Importantly, it is also a segmented genome that allows it to have large genetic diversity.
Is it true or false that hiv uses reverse transcriptase to make ds RNA copies of its DNA genome?
False. HIV uses reverse transcriptase to make single-stranded RNA copies of its RNA genome.
Are enteroviruses RNA viruses?
Yes, enteroviruses are RNA viruses belonging to the Picornaviridae family. Their genome is composed of single-stranded RNA.
What is an antigenome?
An antigenome is a complementary strand of RNA from which the genome of a virus is constructed.
Which RNA makes the proteins go back to the original RNA to make DNA?
The RNA that facilitates the reverse transcription of RNA back into DNA is called reverse transcriptase. This enzyme is often associated with retroviruses, such as HIV, which utilize it to convert their RNA genome into DNA, allowing integration into the host's genome. The process enables the viral RNA to be replicated and expressed as a part of the host's DNA.

False. HIV uses reverse transcriptase to make single-stranded RNA copies of its RNA genome.
RNA viruses are also called?
Viruses with RNA as their genetic material are called retroviruses. They use the enzyme reversetranscriptase to transcribe their RNA genome into DNA, which is then inserted into the host's genome.
Are enteroviruses RNA viruses?
Yes, enteroviruses are RNA viruses belonging to the Picornaviridae family. Their genome is composed of single-stranded RNA.

Is west nile a DNA or RNA virus?
West Nile virus is a virus with a single stranded RNA genome (ssRNA)
What enzyme matches RNA nucleotides to complementary DNA nucleotides?
The enzyme that matches RNA nucleotides to complementary DNA nucleotides is called reverse transcriptase. It is used by retroviruses like HIV to convert their RNA genome into DNA before integrating it into the host cell's genome.
What is the purpose of transcriptase?
Reverse transcriptase is the viral enzyme responsible for making a DNA copy of the RNA genome from a retrovirus. As such, it is technically known as an RNA-dependent DNA polymerase. This is opposite to the usual flow of genetic information from DNA to RNA to protein. This allows a virus with an RNA genome to make copies of itself that can be integrated into the DNA of its host.
Why is bacteria are different from protozoa?
Bacteria have simple genomes and are prokaryotes Protozoa are eukaryotes with more complex genomes (the ameoba has a 670 billion base pair genome! compared to the human 3.2 billion)
Is the HIV virus double-stranded?
No, HIV is a retrovirus - it has a single-stranded RNA genome.
Are DNA genomes found in all organisms and viruses?
yes, but many viruses do not have DNA genome, but RNA genome.
