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

Which of these structures are used by bacteriophages to attach?

Tail fibers: Tail fibers are used by bacteriophages to attach to host cell receptors.

The tail fibers are made up of five different proteins.

These proteins bind to each other to form a tail fiber..

Can Viruses grow and develop?

Living things grow. They use energy and nutrients to become larger in size or more complex. Viruses manipulate host cells into building new viruses which means each virion is created in its fully-formed state, and will neither increase in size nor in complexity throughout its existence. Viruses do not grow.

What is the correct sequence of events in viral reproduction quizlet?

adsorption, release, maturation, replication, assembly, penetration. adsorption to the host cells.

What are the two cycles of viral replication?

1: Lytic versus lysogenic cycle: A temperate bacteriophage has both lytic and lysogenic cycles. In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is incorporated into the host genome, where it is passed on to subsequent generations.

How Viruses are transferred?

Viruses can be transmitted in a variety of ways. Some viruses can spread through touch, saliva, or even the air. Other viruses can be transmitted through sexual contact or by sharing contaminated needles. Insects including ticks and mosquitoes can act as “vectors,” transmitting a virus from one host to another.

What must happen after the virus enters the cell for effective viral replication to take place?

For the virus to reproduce and thereby establish infection, it must enter cells of the host organism and use those cells’ materials. To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane.

Which body system is mainly affected by Creutzfeldt Jakob disease?

The pattern of symptoms can vary depending on the type of Creutzfeldt-Jakob disease (CJD). In sporadic CJD, the symptoms mainly affect the workings of the nervous system (neurological symptoms) and these symptoms rapidly worsen in the space of a few months.

How can we prevent virus replication?

One feasible way of stopping viral replication is to target the genetic machinery involved in the process – namely by cleaving, or splitting, the DNA or RNA strands so that they can no longer function correctly.

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

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

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.

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.

What is the protective protein coat of a virus called?

capsidA virus particle consists of DNA or RNA within a protective protein coat called a capsid.

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.
