All of the following are general properties of Viruses except -
Properties of viruses 

Viruses are obligate intracellular parasites
They lack enzymes necessary for protein and nucleic acid synthesis and are dependent for replication on the synthetic machinery of host cells → so, they cannot grow in cell-free culture media.
They do not have a cellular organization.
They are unaffected by antibacterial antibiotics.
They contain only one type of nucleic acid, either RNA or DNA, never both.
They multiply by a complex process and not by binary fission.
The extracellular infectious virus particle is called the virion.
With few exceptions, viruses are very heat labile.
May contain both DNA and RNA
Form extracellular infectious particles
Heat labile
Not affected by antibiotics
