Question

please number the answer and make them short and clear thanks!

Genetic regulation plays a huge role in organismal development. How does genetic regulation influence a developing embryo? On the following diagram of an operon, label the regulatory gene, promoter, operator and structural genes (assume the operon is oriented so that the proteins read it left to right). Write in the correct labels underneath the corresponding section on the diagram. Now indicate the region where the repressor proteins will bind to block the transcription of the structural genes. Humans (and other organisms too) produce far more proteins than we have genes. How is this possible, if genes are what code for the proteins? True False Scientists are particularly interested in the engineering and cloning of pigs because they hope to make pigs that can act as organ donors to humans. • Dolly and Cc: were cloned using the same technology: nuclear transfer technology. Choose either Dolly or Cc: and summarize the process by which she was cloned

Answer 1

Genetic regulation means regulation at the level of gene.

As you as known that transcription factor function in various expression of various gene.

In developing embryo, various transcription factor regulate and some genetic factor regulate the TRANSCRIPTION and thus translation and thus function of embryo which finally results in development of embryo.

The first dark blue region is the regulatory gene and then the pale blue and the white regions of the first white part containing gene is promoter and only the white part of this gene is operator which means operator is present within promoter.

Then the last 3 is the structural gene as assume Lac Z and Y and A

repressor will not to the operator regions and which will repress the transcription by affecting the binding of RNA polymerase with promoter regions

Human or many other can produce huge amount of protein in less amount of genetic material because , mature mRNA is produced after splicing ,is a process which cleaves the introns and add the exons and then exported to CYTOPLASM and makes protein by translation but this introns regions can be also added sometimes by alternative splicing and can results in different proteins.

False because there is huge difference in the organs and they will be treated as antigen.

Incase of Dolly, ovum and mammary gland cells was isolated and mammary cells was induced into GO phase.

From ovum nucleus was isolated and makes enucleated oocyte .

Then this two cells was fused and activated to make renucleated oocytes .

Then it was cultured in embryo culture and then it was implanted into the foster mother where development process happend and Dolly birth.

As there the genetic material used was of existing sheep , the newly originated Dolly will be clone of the sheep whose mammary gland cells were used.
