A virus is the smallest infectious agent which only replicates in a living host as plant, animal, and bacteria. Without a host cell, it cannot do its metabolic activities. They are made up of DNA and a protein coat called the capsid.Answer and Explanation: (a) A ...
The concept of mRNA vaccines was initially developed in the 1990s9,10. The basis of this technology is the delivery of mRNA encoding an antigen from a target pathogen to the host’s cells. These cells then produce the antigen, which the immune system recognizes as foreign, resulting in an ...
Typically the protein coat, or capsid, of an individual virus particle, or virion, is composed of multiple copies of one or several types of protein subunits, or capsomeres. Some viruses contain enzymes, and some have an outer membranous envelope. Many viruses have striking geometrically regular...
virus des animaux, proteine, virus de los animales, proteinas, herpetoviridaeAlthough herpesviruses have a wide host range and their genomes vary substantially in size, the nucleocapsid appears to be a conservative element of viral design. The capsid shell is icosahedrally symmetric ( T = 16),...
Keywords: mycovirus; phytopathogen; virus; fungi; RNA interference 1. Introduction Theobroma cacao L. is one of the most important cash crops in many tropical regions of the world, with planted areas comprising ~8.2 million ha [1]. The nuts are used to make chocolate and cosmetics [2]. The...
Ad is a non-enveloped virus that is known to mostly cause infections of the upper respiratory tract but can also infect other organs such as the brain and bladder. It possesses an icosahedral protein capsid that accommodates a 26- to 45-kb linear, double-stranded DNA genome. The Ad genome...
Channel catfish virus (CCV) has the gross morphology of a herpesvirus, although no relationship to other herpesviruses is evident from the sequences of its proteins. To examine CCV capsid architecture more closely, we have determined its structure by cryoelectron microscopy and three-dimensional ...
