What is the structure of adenovirus?
The adenovirus particle consists of an icosahedral protein shell surrounding a protein core that contains the linear, double-stranded DNA genome (Fig. 67-2). The shell, which is 70 to 100 nm in diameter, is made up of 252 structural capsomeres.
Are adenoviruses DNA viruses?
Adenoviruses are medium-sized (90-100 nm), non-enveloped icosohedral viruses with double-stranded DNA. More than 50 types of immunologically distinct adenoviruses can cause infections in humans.
What is adenovirus known for?
Adenoviruses are common viruses that typically cause mild cold- or flu-like illness. Adenoviruses can cause illness in people of all ages any time of year. You can protect yourself and others from adenovirus infection: wash your hands often with soap and water for 20 seconds.
What are the genomic properties of adenovirus?
The adenovirus genome is a single linear molecule of double-stranded DNA (26 163–48 395 bp) containing an inverted terminal repeat (ITR) of 30–371 bp at its termini, with the 5′ ends of each DNA strand linked covalently to a virus-coded terminal protein (TP). The nucleotide composition is 33.6–67.6% G + C.
What viruses are DNA viruses?
DNA viruses comprise important pathogens such as herpesviruses, smallpox viruses, adenoviruses, and papillomaviruses, among many others.
How are adenoviruses different from other viruses?
There are many different types of adenoviruses, so people can get infected more than once. These viruses don't have a “season” like other viruses (the flu, for example), so infections can happen at any time of the year.
What kind of DNA does adenovirus have?
double-stranded DNA genomeAdenovirus (Ad) has a linear, double-stranded DNA genome with inverted terminal repeats at each end that contain the origins of viral DNA replication.
Which of the following is not a DNA virus?
Rabies virus is not a DNA virus (option-c). Genome of Herpes virus is double-stranded DNA which is linear in structure. Rabies virus has RNA in its genome which is antisense and single-stranded. Bacteriophage is a virus which kills bacteria.
