Viruses are the infective particles present in the environment which encloses their genetic material which could be wither RNA or DNA enclosed in the protein coat.
The protein coat is made of the capsomers which are arranged in the tubular structure forming capsid. The viruses do not contain the metabolic machinery of their own that is the reason that they do not have replication or transcription or translation machinery. For this they are dependent on the host organisms as they use their machinery.
Magnetic reversal proves seafloor spreading because we can see the polarity of the Earth's magnetic field in rocks. As magma cools, particles in it get “frozen” in the direction of the magnetic field. ... The magnetic evidence shows that the oldest rocks are far away from the ridge and the newest rocks are closest.
