Question

What are the advantages & disadvantages of an infomation transfer system that uses a physical pattern/template

Answer 1

Having the template it can be folded to store then opened to use.

It can be permanently tailored to use by specialized differentiating cell lineages as they progress through development stages.

It can have built in regulation or control documentation encoded along with translatable reading frames.

It can be hidden from tampering ( inside cell membrane at least but some go further with it hidden inside nucleus). When inside a nucleus it can have more controls added to template transcriptions and the transcripts. This aids in allowing intercellular communication to cross coordinate cell regulation in multicelled organisms.

It can be self referential for repair. Having the information in chemically different base pairs ensures protection from both bases being altered simultaneously and the information lost.

A disadvantage is the template can be usurped as by a virus for its own use.

The template machinery is complicated and expensive to maintain and repair. This is a reason single celled organisms are less involved and less specialized that multicelled organisms that can afford to invest more resources in template handling, repair to go with the intercellular coordination/communication.
