WHERE TO GO NOW. While R-404A, the most popular refrigerant for commercial supermarket refrigeration, is labeled as needing POE oils, the industry has introduced a range of HFC refrigerants that do work with a range of lubricants, including mineral oil, for specific retrofit applications.
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers.The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres.The capsid encloses the genetic material of the virus.uring this process, new capsid subunits are synthesized according to the genetic material of the virus, using the protein biosynthesis mechanism of the cell. During the assembly process, a portal subunit is assembled at one vertex of the capsid.
Rating Newest Oldest. Best Answer: A capsid is the protective protein coat that surrounds a virus. It has 2 functions: 1) protects the nucleic acid of the virus from attack by host's defensive cells 2) attaches to a specific receptor site of a cell membrane. Source(s): Jake Â· 6 years ago.
