Please solve the riddle, how can a virus encode a protein larger than the size of its genome?
Viruses can be express their genome by cellular machinery that can support their life cycle than can encode a very few of their own genes initially by a polyprotein that can undergoes the proteolytic processing and the molecular genetics analyses of viral gene expression have revealed many processing events that are mediated by virus-encoded proteinases. The biochemical activity and the structural analyses of the viral enzymes reveal the remarkable similarities of cellular proteinases. The proteinases reactions that are catalyzed by viral proteinases are not so simple enzyme interactions rather than the processing steps that are highly regulated and can coordinate with other viral processes and are very frequently involve in the participation of other factors.
The viruses with large DNA genomes that can encode hundreds of proteins called as giruses and are being discovered with increasing frequency which review the concentrates of viruses with in the genome excess of 300 kb and also focuses on partially characterized viruses with in annotated genomes.Viruse that have adopted a parasitic lifecycle that reprogram it to neglect to its own vital functions and instead of devote itself of making many replicas of the virus and then it can lyses the cell to spread to new cells, The viruses that are enigmatic with respect to genes and particle structure results in means of replication and transmission that are not considered for further DNA-containing viruses that have genomes ranging more.
The repeating subunits of viruses to assemble capsids at the minimal genetic expense can also protect their precious genetic cargo in the harsh of extracellular environment that can be seen, unnecessary genes that are reusing the blueprints for proteins that needs a greatest abundance in viral genomes that are parsimonious of lacking the long stretches of noncoding the DNA that can be with in extraneous nucleotides and some viruses that have also eliminated individual start and stop signals for each of their protein that can found in cellular genomes rather than protein encode gene.
