It is quite intriguing that most virus capsids are either icosahedral or helical in structure. Presumably, these two structures were the ideal structures to protect a viral genome and accessory proteins within a virus particle.elical Capsid. Helical capsids are usually formed from one protein that interlocks to form a helix-like structure around the viral genome. They are usually more common among viruses that infect plants, though influenza, measles, mumps and rabies viruses all have helical capsid structures.
1 RF modulator converts AV to RF channel.  Consumes 9 VDC input voltage and offers Antenna interfaces/ports for reliable transmission.
Radio Frequency, or RF, is the mode of communication that is used by most radio devices, from deep space communication networks to cell phones. CB radios use RF transceivers.Some TV remote controls use RF. Cordless phones use RF. A standard radio is the most obvious receiver of radio signals.RF is used to send signals to remote control toys. Wireless routers use RF technology.ome TV remote controls use RF. Cordless phones use RF. A standard radio is the most obvious receiver of radio signals.
