Southwestern Community College Biology DNA and Gene Expression Worksheet

Biology: complete the following worksheet by answering all the questions

Context:This assignment concerns a boy born without eyes. With any severe developmental difference, there couldbe a specific explanation in the DNA. You will be presented with several pieces of information. Your job isto look at the evidence and write some biological explanations.

Your Writing Assignment.Your goal is to use the evidence above to write a biological explanation about what might be happening inthe boy born without eyes. You should include:• Whether the boy’s karyotype can explain why the boy was born without eyes.• What is the function of Pax6 protein, using the information about the domain structure and geneexpression above.• How each mutation may affect the function of Pax6 protein and which would be more severe.• What it means for the boy to have only the 2 versions of the Pax6 (both of which have a mutation)and why he might have been born without eyes
