Virosome. A virosome is a drug or vaccine delivery mechanism consisting of unilamellar phospholipid membrane (either a mono- or bi-layer) vesicle incorporating virus derived proteins to allow the virosomes to fuse with target cells. Viruses are infectious agents that can replicate in their host organism, however virosomes do not replicate.
Virome refers to the assemblage of viruses [1][2] that is often investigated and described by metagenomic sequencing of viral nucleic acids [3] that are found associated with a particular ecosystem, organism or holobiont. The word is frequently used to describe environmental viral shotgun metagenomes. Viruses, including bacteriophages, are ...
Liposome. Scheme of a liposome formed by phospholipids in an aqueous solution. Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size ...

A chromosome is a package of DNA with part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome -forming packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA ...
Illustration of a eukaryotic cell membrane Comparison of a eukaryotic vs. a prokaryotic cell membrane. The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).
Viroplasm. Viroplasms (green) in cells infected with rotavirus (top), and uninfected cells (bottom). (Immunofluorescent stain) A viroplasm, sometimes called " virus factory " or " virus inclusion ", [1] is an inclusion body in a cell where viral replication and assembly occurs. They may be thought of as viral factories in the cell.
A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. [ 1 ][ 2 ]Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes ...
