what is difference between dna virus and rna virus?

Compared to DNA virus genomes, which can encode up to hundreds of viral proteins, RNA viruses have smaller genomes that usually encode only a few proteins.

What is the difference in what they do? DNA stores and transmits genetic information. RNA acts as a template for making proteins.

Unlike double-stranded DNA, RNA is a single-stranded molecule in many of its biological roles and consists of much shorter chains of nucleotides. ... While the sugar-phosphate "backbone" of DNA contains deoxyribose, RNA contains ribose instead.

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.

We observed that DNA viruses are able to attack both human cellular and metabolic processes simultaneously during infections. On the other hand, RNA viruses preferentially interact with human proteins functioning in specific cellular processes as well as in intracellular transport and localization within the cell.

All true viruses contain nucleic acid—either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid)—and protein. The nucleic acid encodes the genetic information unique for each virus. The infective, extracellular (outside the cell) form of a virus is called the virion.

An RNA virus is a virus that has RNA (ribonucleic acid) as its genetic material. ... Viruses with RNA as their genetic material which also include DNA intermediates in their replication cycle are called retroviruses, and comprise Group VI of the Baltimore classification.

The DNA is a double-stranded molecule, while the RNA is single-stranded- formed from the DNA during transcription. Based on that, another difference between both is that the DNA polymerase manufacture double-stranded DNA while the RNA polymerase manufacture a single-stranded RNA.

Structural differences. DNA is double stranded, forms a double helix (the two strands spiral around each other) is stable and stays in the nucleus. RNA is single stranded (except in rare cases), can fold into complex 3D shapes, is relatively unstable and can leave the nucleus.

So DNA and RNA nucleotides differ according to which five-carbon sugar is present, and whether the nitrogenous base thymine or uracil is present. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil.

Viral families are grouped based on their type of nucleic acid as genetic material, DNA or RNA 6. DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. RNA viruses have typically ssRNA, but may also contain dsRNA.

RNA is different from DNA is three ways: (1) the sugar in RNA is ribose not dioxyribose; (2) RNA is generally single-stranded and not double-stranded; and (3) RNA contains uracil in place of thymine.

DNA and RNA are different from their structure, functions, and stabilities. DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Also, DNA is double-stranded and RNA is single-stranded which is why RNA can leave the nucleus and DNA can't.

Summary of Differences Between DNA and RNA DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable.

Also, RNA nucleotides contain ribose sugars while DNA contains deoxyribose and RNA uses predominantly uracil instead of thymine present in DNA. ... This base is also a pyrimidine and is very similar to thymine. Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA.

What are the similarities and differences among viral genomes? All viral genomes are composed of nucleic acid and carry genes. They differ in that some genomes are DNA whereas others are RNA. Some are single stranded and others are double stranded.

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.
