Steps of Viral Replication, Overview

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Most viral infections proceed through six steps in order: attachment, entry, uncoating, replication, assembly, and release of new virions.

Show

A bacteriophage attaches, injects its genome, replicates inside the host, assembles new phages, then lyses the cell to release them.

Watch for

Skipping a step, such as failing to uncoat the genome, halts the cycle — a virus cannot replicate past a blocked step.
