To replicate, a virus or its genetic material must be in a living 
.

BlackTom AI · Accepted Answer

The statement asks what a virus or its genetic material must be in order to replicate.
Since viruses cannot carry out metabolic processes on their own, they require the cellular machinery of a living cell to copy their genetic material and assemble new viral particles. Therefore, the missing word is 'cell.'
If we consider the nature of viruses, they are inert outside host cells and rely entirely on the host cell's enzymes, ribosomes, nucleotides, and energy to replicate. This is contrast to cellular life, which can perform replication and metabolism independently to some extent.
There aren’t alternative options provided in the list to evaluate here (the only option is the blank label). However, it’s important to note that claiming replication occurs without a living cell would ignore the reliance viruses have on host cell machinery, and would contradict established virology concepts.
In summary, replication of a virus requires being inside a living cell where the host’s molecular tools enable genome replication and virion production.
