RNA
West Nile virus contains strands of RNA.
West Nile virus is a virus with a single stranded RNA genome (ssRNA)
Ebola is a retrovirus so the genetic material is single-stranded RNA (ssRNA)
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.
West Nile virus does not have a nucleus because it is not a cellular organism; it is a virus. Viruses are made up of genetic material (either DNA or RNA) surrounded by a protein coat, and they lack the cellular structures that define living cells, such as a nucleus. Instead, they replicate by infecting host cells and hijacking the host's cellular machinery.
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
An uracil base is in RNA but not in DNA
RNA has the base uracil that DNA does not have.
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.
Comparing DNA and RNA, some key differences include: DNA is double-stranded, while RNA is single-stranded; DNA contains deoxyribose sugar, RNA contains ribose sugar; DNA has thymine base, RNA has uracil base; DNA is found in the nucleus, RNA is found in the cytoplasm; DNA is stable, RNA is less stable; DNA is the genetic material, RNA is involved in protein synthesis. These are just a few of the many distinctions between DNA and RNA.
Uracil is a nucleotide found in RNA but not in DNA. In RNA, uracil replaces thymine, which is found in DNA.
