A virus is a biological agent which requires a suitable host cell for its survival and replication. It replicates by using the biological mechanism of the host cells. It infects the prokaryotes as well as the eukaryotes and is responsible for causing many infectious diseases in other organism and in the human beings. The term virology refers to the study of viruses. There are various types of viruses and are categorized on the basis of the genomic characters of the viruses as well as the hosts.

Summary Introduction

A virus is a biological agent which requires a suitable host cell for its survival and replication. It replicates by using the biological mechanism of the host cells. It infects the prokaryotes as well as the eukaryotes and is responsible for causing many infectious diseases in other organism and in the human beings. The term virology refers to the study of viruses. There are various types of viruses and are categorized on the basis of the genomic characters of the viruses as well as the hosts.

Expert Solution & Answer

Explanation of Solution

The viruses are defined as a distinctive group of acellular, minute, obligate intracellular parasites and require a host in order to complete their life cycle. It typically consists of genetic material (either DNA or RNA) and is enclosed within a protein coat which forms a complete viral particle known as virion.

The minimal features that are needed to fit this definition include size, shape, structure, genome arrangement, host dependency, and symmetry of the viruses.

The viruses are smaller than the prokaryotes and its shape and size ranges between 20-300 nm (0.02 – 0.3 μm).

The viral genome is enclosed within a capsid which is a protein coat. It is formed by the structural units called capsomeres. The capsomeres are arranged in a specific pattern by surrounding the nucleic acids. The number of capsomeres varies from virus to virus and this gives the symmetry to the virus.

The viruses depend on the host cell for its survival and replication.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
