What else can I help you with?
Do viruses contain RNA?
yes
What are viruses genetic materia?
Viruses contain either DNA or RNA.
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.
Viruses contain DNA and RNA true or false?
Yes. Although not both together, a virus contains a nucleic acid, either single stranded or double stranded DNA or RNA.
Does Virus contain both DNA and RNA?
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.
Is there anything that does not contain DNA?
Yes. Anything that isn't an organism will not contain DNA. For example, rocks do not have DNA. Additionally, some viruses have RNA instead of DNA although viruses would be covered by the first category mentioned.
Does RNA virus have Reverse transcriptases in them?
The RNA viruses that contain reverse transcriptases are collectively called retroviruses among which are: HIV, human immunodeficiency virus (AIDS); RNA tumor viruses (leukemia)
What is the difference between DNA viruses and RNA viruses?
There are several differences for example; most DNA viruses use the DNA polymerases of of the host cell to synthesize new genomes along the templates provided by the viral DNA, in contrast to replicate their genomes, RNA viruses use virally encoded polymerases that can use RNA as a template. RNA viruses usually retain their RNA within capsids, whilst DNA viruses are less "packaged" usually retained within say a head, or a capsomere. The main difference of course, is that DNA viruses contain either a doubled stranded DNA (dsDNA) or a single stranded (ssDNA), and RNA viruses contain dsRNA or ssRNA. There are of course several other differences, but these are the ones I know of.
Do viruses need to contain genetic material?
They need either DNA or RNA.
What genetic material is in both viruses and bacteria?
Both viruses and bacteria contain genetic material in the form of DNA or RNA. Viruses can have either DNA or RNA as their genetic material, while bacteria typically have DNA as their genetic material.
Do all viruses have protein coats?
yes
Do virus have protein coat?
Yes. Viruses contain a protein coat called a capsid. Inside this capsid will be DNA or RNA but never both. Viruses that contain RNA are called retroviruses. They also contain the enzyme reverse transcriptase that allows them to convert RNA into double-stranded DNA once it infects a cell.
