What is the difference between RNA virus and DNA viruses?
The genetic material of a virus can be either DNA or RNA. The viruses that contain DNA as their genetic material are called the DNA viruses. RNA viruses, on the other hand, contain RNA as their genetic material. DNA viruses are mostly double-stranded while RNA viruses are single-stranded.
What are the differences between DNA virus and RNA viruses quizlet?
What are some differences between the replication of DNA and RNA viruses? DNA – Enter the host cell’s nucleus where the viral DNA is replicated. RNA is produced which moves into the host cell cytoplasm where viral proteins are produced. Some viruses with DNA may integrate their viral DNA into the host’s normal DNA.
Is Covid an RNA or DNA virus?
COVID-19, short for “coronavirus disease 2019,” is caused by the novel coronavirus SARS-CoV-2. Like many other viruses, SARS-CoV-2 is an RNA virus. This means that, unlike in humans and other mammals, the genetic material for SARS-CoV-2 is encoded in ribonucleic acid (RNA).
What are the 3 differences between DNA and RNA?
So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
Which is not a difference between RNA and DNA?
Answer and Explanation: The correct answer is: (c) DNA contains alternating sugar-phosphate molecules whereas RNA does not contain sugars. See full answer below.
What is the difference between replication in DNA virus RNA virus and retrovirus?
DNA viruses contain DNA in the genome while RNA viruses contain RNA. The replication of DNA viruses occurs inside the host’s nucleus while it occurs in the host’s cytoplasm in RNA viruses. The main difference between DNA and RNA viruses is the type of genetic material and replication inside the nucleus.
Which stage of the viral life cycle is the most different between DNA and RNA viruses?
Replication: After the viral genome has been uncoated, transcription or translation of the viral genome is initiated. It is this stage of viral replication that differs greatly between DNA and RNA viruses and viruses with opposite nucleic acid polarity.
What are the 3 basic differences between DNA and RNA?
What is the biggest difference between DNA and RNA?
Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.
How do viruses get their DNA or RNA?
Viruses make use of an enzyme called a ‘polymerase’ to copy their genetic code. DNA viruses make use of the enzyme ‘DNA polymerase’ – DNA polymerases are able to proofread the newly copied viral DNA and go back and fix errors (like the ‘spell check’ function). DNA viruses therefore have fewer mutations when they are copied. RNA
Can a virus contain both RNA and DNA?
Yes,a virus can have both RNA and DNA. Take the example of retrovirus. They have two single stranded RNA. But when they are in host the RNA is transcripted into DNA. The DNA is used for further RNA formation,coding for protein of the virus. Then the virus forms again and attack another cell.
How does RNA compare to DNA?
DNA has the bases adenine,thymine,guanine,cytosine. RNA has the bases adenine,uracil,guanine,cytosine.
Do viruses have both DNA and RNA?
Viruses typically store their genetic information encoded in molecules of either DNA or RNA — either one or the other but not both. In April of 2012, however, scientists at Portland State University discovered an unusual virus with a genome made from both RNA and DNA.
