On the other hand, viral proteins are rich in intrinsic disorder. Some of the intrinsically disordered regions are heavily used in the functioning of viral proteins. Others likely have evolved to help viruses accommodate to their hostile habitats. Still others evolved to help viruses in managing ...
What kinds of nucleic acids do viruses contain? Viruses are particles that: a. contain DNA or RNA which can be injected into a cell. b. have an exterior coat composed of protein. c. can contain an enzyme which catalyzes the reaction to make DNA from the viral RNA. d. All of these ...
The importance of eIF-2 as a regulatory mechanism for protein synthesis is illustrated by the wide variety of strategies employed by viruses to down-regulate PKR. Thus, Vaccinia virus encodes K3L protein, which resembles eIF-2 and acts as...
including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
The replication initiator proteins of viruses in this genus are called Rep (Rep1 or Rep68/78), rather than NS1. All members of the genus are homotelomeric, and their virions contain equivalent numbers of separately packaged positive or negative DNA strands, between 4.7 and 5.1 kb in size....
DNA vaccines have been developed against various fish viruses, including rhabdoviruses, herpesviruses, orthomyxoviruses, betanodavirus, togaviruses, birnaviruses, and iridovirus. A recombinant DNA vaccine containing the puK-SPDV-poly2#1 plasmid, encoding several proteins from SAV-3 (CLYNAV), has ...
There are different types of flu vaccines, all of which are similarly effective. Some vaccines contain influenza viruses that have been chemically disrupted (inactivated), so they cannot replicate. Others, known as subunit vaccines, contain only purified virus antigens (proteins that elicit an immune...

Ribonucleic acid (RNA) is a molecule found in cells that does many tasks for the human body, including the transformation of DNA information into proteins. Learn about RNA viruses and their replication strategies. Explore the features and viruses of RNA, such as double-stranded, positive and neg...
How are DNA, RNA, and proteins related in the cell? Why do larger viruses have DNA and not RNA? RNA viruses mutate and evolve faster than other viruses. Why? All living organisms have both DNA and RNA. A virus has either DNA or RNA but not both. So what does that tell us about ...
