DNA

(biochemistry)

DNA

deoxyribonucleic acid; a nucleic acid that is the main constituent of the chromosomes of all organisms (except some viruses). The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA is self-replicating, plays a central role in protein synthesis, and is responsible for the transmission of hereditary characteristics from parents to offspring

It is noteworthy that in SV40 transformed mouse 3T3 cells hexose transporters are relocated from microsomal membranes to plasma membrane, suggesting that oncogenic DNA viruses utilize not only transcriptional regulation of glucose transport but also alterations in transporter trafficking during transformation [54].
The evidence for persistence of viral genetic material in cells transformed by DNA viruses is summarized:
In a paper published August 17, 2012, in the journal Cell, HHMI early career scientist Harmit Malik at the Fred Hutchinson Cancer Research Center and Nels Elde, a former postdoctoral researcher in Malik's lab who is now at the University of Utah School of Medicine, report on one way that double-stranded DNA viruses keep up with the ever-changing defenses of the immune system.
Indeed, SV40 may be the most extensively studied of all DNA viruses due to its conveniently small genome and its many historical and current uses in genetic engineering, molecular biology, and cancer research.
Human papilloma viruses are double stranded circular DNA viruses.
Hepatitis C is an RNA virus - RNA viruses mutate much more than DNA viruses, making it harder for the body's immune system to locate and destroy them.
Recurrent respiratory papillomatosis (juvenile laryngeal papillomatosis) is a rare disease caused by herpes simplex, one of the DNA viruses, (1,2) but it is the most common benign neoplasm of the larynx and the most common cause of hoarseness in children.
Human polyomaviruses are nonenveloped DNA viruses measuring approximately 45 nm in diameter.
DNA viruses probably also came from very ancient times, maybe before the separation of the three domains (2).
In particular, he notes, viruses that have RNA rather than DNA for genetic material make numerous errors during replication and appear to have none of the "proofreading" mechanisms that help DNA viruses eliminate such mistakes.
Colonno has co-authored over 135 original scientific articles on a wide variety of RNA and DNA viruses, presented to worldwide regulatory agencies, and presented his original research at major scientific and medical meetings.
