Difference Between ssDNA and dsDNA

dsDNA is the double stranded DNA whereas ssDNA is the single stranded DNA, and although both of them carry genetic material they have a number of differences (Table 1).

What does ssDNA mean?

Anti-single-stranded DNA [ssDNA] is sometimes also measured. It is non-specific and gives no useful information to a physician. Patients who do not have anti-dsDNA usually have a related antibody, anti-Sm.

Is there a single stranded DNA?

They can be divided between those that have two strands of DNA in their genome, called double-stranded DNA (dsDNA) viruses, and those that have one strand of DNA in their genome, called single-stranded DNA (ssDNA) viruses.

What is the difference between ssRNA and dsRNA?

The key difference between ssRNA and dsRNA is that ssRNA has only one strand of RNA while dsRNA is made up of two complementary siRNA or miRNA strands. RNA or ribonucleic acid is a type of nucleic acid which is made up of ribonucleotides. ... Lighter particles are ssRNA viruses, while denser particles contain dsRNA.

Why DNA is double stranded and RNA is single stranded?

DNA was chemically more stable than RNA so it was possible to maintain greater length of DNA in comparison to RNA. RNA has hydroxyl group (OH) present on the 2' carbon. This hydroxyl group invites hydrolysis reaction and so it was not possible to maintain long length RNA molecule.

What does a high ssDNA mean?

A high level of anti-dsDNA in the blood is strongly associated with lupus and is often significantly increased during or just prior to a flare-up. When the anti-dsDNA is positive and the person tested has other clinical signs and symptoms associated with lupus, it means that the person tested likely has lupus.

What is anti Sm antibody?

Background: Anti-Smith (Sm) antibody is a highly specific antibody for systemic lupus erythematosus (SLE). ... The longitudinal association between disease activity and anti-Sm antibodies was also evaluated in total patients and in those with anti-Sm antibodies.

What viruses are DNA based?

DNA viruses comprise important pathogens such as herpesviruses, smallpox viruses, adenoviruses, and papillomaviruses, among many others.

What viruses are DNA viruses?

DNA virus: A virus in which the genetic material is DNA rather than RNA. The DNA may be either double- or single-stranded. Major groups of double-stranded DNA viruses (class I viruses) include the adenoviruses, the herpes viruses, and the poxviruses.

Are all viruses DNA?

Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.

Why is RNA virus more dangerous?

RNA viruses generally have very high mutation rates compared to DNA viruses, because viral RNA polymerases lack the proofreading ability of DNA polymerases. The genetic diversity of RNA viruses is one reason why it is difficult to make effective vaccines against them.

What does RNAi stand for?

Introduction. RNAi stands for 'RNA interference', which is the silencing of gene expression by the administration of double-stranded RNA (dsRNA).

What is DNA virus and RNA virus?

DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. ... 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.
