The comparison and differences between icosahedral and filamentous symmetry of viruses with examples. Introduction: The viral capsid protects and encloses the genetic material of a virus. It is a proteinaceous structure that can be either symmetric or asymmetric. During replication or reproduction of a virus, the genetic material is inserted into the host cytoplasm and the capsid remains outside.

The comparison and differences between icosahedral and filamentous symmetry of viruses with examples.

Introduction:

The viral capsid protects and encloses the genetic material of a virus. It is a proteinaceous structure that can be either symmetric or asymmetric. During replication or reproduction of a virus, the genetic material is inserted into the host cytoplasm and the capsid remains outside.

Expert Solution & Answer

Explanation of Solution

The symmetrical capsid of virus can be of two types: icosahedral and filamentous. This symmetrical geometry proves to be advantageous in packaging the repeating protein units that are produced from the genetic material of the virus. The differences between these shapes of viral capsid are given below:

1. The icosahedral capsid contains 20 triangular faces and each face is formed by three identical proteins that are asymmetrical. The filamentous capsid is composed of monomers that spiral around the genome of the virus.

2. The size of an icosahedral capsid is fixed, however, the length of a helical (filamentous) capsid can be increased to include larger sized nucleic acid of virus.

3. The filamentous viruses contain tail fibers at their end that mediate attachment to host cell surface. The icosahedral virus contains glycoprotein spikes in their membrane envelope to aid in attachment.

4. The example of viruses having icosahedral capsid are human immunodeficiency virus (HIV) and herpes simplex virus. The examples of filamentous virus are Ebola virus, influenza virus, and tobacco mosaic virus.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
