In What Order Do The Steps Of Viral Replication Take Place Quizlet?

What is the function of the cilia found around the inner surface of the windpipe in the respiratory tract )?

The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways.

Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms..

What 2 components do all viruses contain?

The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

How many viruses can be in a single drop of blood?

One Drop Of Blood Can Reveal Almost Every Virus A Person Has Ever Had. A new experimental test called VirScan analyzes antibodies that the body has made in response to previous viruses. And, it can detect 1,000 strains of viruses from 206 species.

What are the steps involved in viral replication quizlet?

Terms in this set (7)Attachment or Absorption. Viral particle attaches to host cell via specific receptors on on the surface of the host cell. … Penetration. Entry of viral nucleic acid into host cell. … Uncoating. separation of nucleic acid from the protein capsid coat. … Integration. … Synthesis. … Maturation or Assembly. … Release.

What are the 4 steps in the correct order of virus infection?

Steps of Virus Infections (text version)Step 1: Attachment: The virus attaches itself to the target cell.Step 2: Penetration: The virus is brought into the target cell.Step 3: Uncoating and Replication: The enveloped virus loses its envelope, and viral RNA is released into the nucleus, where it is replicated.Step 4: Assembly: Viral proteins are assembled.More items…

Which is the correct order of viral infection cycle?

Virion assembly and the release from the cell constitute the exit. The life cycle of virus. The virus life cycle could be divided into six steps: attachment, penetration, uncoating, gene expression and replication, assembly, and release.

What are the two types of viral replication?

There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle.

Which stage of virus occurs first?

Attachment is the first stage in the infection process in which the phage interacts with specific bacterial surface receptors (e.g., lipopolysaccharides and OmpC protein on host surfaces).

In what order do the steps of viral replication take place?

Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release.

What happens during the release step in the viral replication cycle?

During release, the newly-created viruses are released from the host cell, either by causing the cell to break apart, waiting for the cell to die, or by budding off through the cell membrane.

What are the five steps of virus replication?

Most productive viral infections follow similar steps in the virus replication cycle: attachment, penetration, uncoating, replication, assembly, and release.

Which of the following steps of viral replication occurs first?

Attachment. It is the first step of viral replication. The virus attaches to the cell membrane of the host cell. It then injects its DNA or RNA into the host to initiate infection.

Can your body kill a virus?

A third mechanism used by antibodies to eradicate viruses, is the activation of phagocytes. A virus-bound antibody binds to receptors, called Fc receptors, on the surface of phagocytic cells and triggers a mechanism known as phagocytosis, by which the cell engulfs and destroys the virus.

Can viruses replicate outside a living organism?

“The virus cannot reproduce itself outside the host because it lacks the complicated machinery that a [host] cell possesses.” The host’s cellular machinery allows viruses to produce RNA from their DNA (a process calledtranscription) and to build proteins based on the instructions encoded in their RNA (a process called …

In which step of the diagram does the virus release a protein?

Answer: The correct answer would be the step E. It represents the lytic cycle of the virus. The viral genome takes over the host cell machinery and used it for the synthesis of its protein coats and genetic material.
