Summary Introduction

To determine: The structure of gram positive cell and its constituents.

Introduction: The bacteria are divided into various categories based on different parameters. Christian Gram devised a method to differentiate bacteria depending upon cell wall composition. . Gram stain demarcates the bacteria into gram-positive and gram-negative bacteria.

Fig.1: The structure of gram positive cell.

The gram positive cells are the cells that can retain the visualizing stain called Christian Gram stain. The gram positive cell is present in the gram positive bacteria. These cells have thick layer of peptidoglycan and several other features that are not present in a gram negative cell. The gram positive cells also have two unique molecules called teichoic acid and lipoteichoic acid that is not present in gram negative bacteria. The gram negative bacteria contains lipopolysaccharide that is exclusive to gram negatibe bacteria only. These are phospholipids that help in the attachment of the peptidoglycan with the phospholipid layer. the surface proteins are embedded in the peptidoglycan and acts as receptor for various cells and tissues.

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.
