What else can I help you with?
Some organisms use singlestranded rather than doublestranded DNA In these organisms which enzyme would probably not be needed for DNA replication?
Some viruses have single stranded DNA molecules. These viruses do not have the machinery to synthesise the DNA on their own. They insert their DNA in a living cell where the DNA synthesis takes place.
What viruses have Rna in their core rather than Dna?
They are called Rna viruses. Rna retro-viruses are a different and somewhat more complex matter.
What are antiretroviral drugs?
Antiretroviral drugs inhibit the reproduction of retroviruses--viruses composed of RNA rather than DNA.
Do all organisms have DNA?
Yes. DNA is the fundamental blueprint for all life on Earth.That depends on your definition of Life.Are viruses alive? Some say yes and some say no. Some viruses have DNA, and some only have RNA. So if you consider viruses a form of life, then some do not have DNA. RNA virus examples are SARS and Hepatitis. If you don't consider viruses alive, then yes, all forms of life (that we know of) higher than a virus contains some form of DNA. You can find out more at the link below.
Is viruses solid?
Viruses are not solid objects. They are microscopic infectious agents that consist of genetic material (either DNA or RNA) enclosed in a protein coat. They are considered to be particles rather than solid structures.
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.
Are DNA genomes found in all organisms and viruses?
yes, but many viruses do not have DNA genome, but RNA genome.
Is single strand DNA or RNA more commonly found in viruses?
RNA is more commonly found in viruses than single-strand DNA.
Is single-stranded DNA or RNA more commonly found in viruses?
RNA is more commonly found in viruses than single-stranded DNA.
What are the two types of nucleic acids viruses may have?
Viruses can have either DNA or RNA (a virus will never have both at the same time, although some viruses can have each one separately at different stages of their life cycles). RNA viruses are much more common than DNA viruses.
Do viruses have circular DNA?
Some viruses have circular DNA genomes while others have linear DNA genomes. The shape and structure of viral DNA can vary depending on the type of virus.
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.
