The processes of transcription and translation as “coupled” in bacteria is described by Microbiologists. This term indicates that a bacterial mRNA can be undergoing transcription, when it is undergoing translation. a) The coupling of possible transcription and translation in bacteria is to be described. b) The possibility of coupling of transcription and translation in single-celled eukaryotes such as yeast is to be cheked. Introduction: Transcription is the process of synthesis of new RNA strands from the template one. There is a synthesis of an RNA strand from deoxy nucleotides of the sense strand. The formation of mRNA replaces the Thymine nucleotide with Uracil. RNA synthesis occurs in the direction of 5'-3' end. Any one of the DNA strands is selected for transcription. In bacteria, to save energy, the process is coupled –transcription and translation, while in eukaryotes, the process is divided and separate - transcription occurs in the nucleus and translation in the cytoplasm. In prokaryotes- the process is DNA-RNA-proteins, whereas in Eukaryotes- DNA-mRNA- RNA processing (posttranscriptional modification) - proteins.

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.
