Verified step by step guidance

Understand the basic structure of a virus, which typically includes genetic material (DNA or RNA), a protein coat called a capsid, and sometimes an envelope.

Learn about the viral replication cycle, which includes several key steps: attachment, penetration, uncoating, replication, assembly, and release.

Recognize that the envelope is a lipid membrane that some viruses acquire from the host cell during the release phase of viral replication.

Identify the process of budding, where the virus acquires its envelope. During budding, the virus exits the host cell by wrapping itself in a portion of the host's cell membrane, forming the envelope.

Differentiate between the steps of viral replication: attachment is when the virus binds to the host cell, penetration is when the virus enters the host cell, and uncoating is when the viral capsid is removed to release the genetic material.
