검증된 단계별 안내

Step 1: Understand the key terms related to viruses and their life cycles. For example, 'uncoating' refers to the process where the viral capsid is removed to release the viral genome inside the host cell.

Step 2: Identify the term 'prophage' as a dormant virus integrated into the bacterial genome, which corresponds to an inactive virus within a bacterial cell.

Step 3: Recognize that a 'retrovirus' is a virus that uses reverse transcriptase to transcribe DNA from its RNA genome.

Step 4: Match 'bacteriophage' to a virus that specifically infects bacteria.

Step 5: Define structural components such as 'capsid' as the protein coat of a virus, 'envelope' as the membrane surrounding some viruses, and 'virion' as the complete, infectious viral particle.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Virus Structure and Components

Viruses consist of a protein coat called the capsid that encases their genetic material. Some viruses also have an envelope, a lipid membrane derived from the host cell, which surrounds the capsid. Understanding these components is essential for identifying terms like capsid, envelope, and virion (the complete virus particle).

Virus Life Cycle and Latency

Viruses can enter dormant states within host cells, such as prophages in bacteria or proviruses in eukaryotic cells. These latent forms integrate into the host genome and can reactivate later. Recognizing these concepts helps distinguish between active infection and viral latency.

Virus Types and Effects on Host Cells

Different viruses infect different hosts, such as bacteriophages infecting bacteria and retroviruses using reverse transcription to replicate. Additionally, viral infections can lead to cellular changes, including benign tumors or cancer, highlighting the impact of viruses on host cell behavior.
