49. In cave-dwelling populations, a mutation to a CRE of Sonic hedgehog (Shh), a secreted from mesoderm cells and Pax6 gene expression by binding to specific causes increased dosage of this protein within the eye modules, a process known as: Paracrine; Enhances; Directly; Enhancer elements; Heterochrony Morphogen; Enhances; Indirectly; Membrane receptors; Heterotypy Paracrine; Represses; Indirectly; Membrane receptors; Heterometry Transcription; Represses; Directly; Silencer elements; Heterotopy factor that is Paracrine; Represses; Directly; Silencer elements; Heterometry

Question 50 (2 points) 50. Continuing with question #49 above, the increased dosage of Shh, or development of both the eye and jaw modules, a process known as increased size relative to the remainder of the skull, a process known as: Heterometry; Individualization; Negative allometry Heterotopy; Serial homology; Positive allometry Heterochrony; Pleiotropy; Positive allometry Heterometry; Pleiotropy; Positive allometry Heterotypy; Dissociation; Negative allometry affects the such that the jaws show

51. The of Pax6 in cave dwelling populations causes the DNA associated with this gene to be into Repression; De-condensed; Euchromatin Activation; De-condensed; Euchromatin Activation; Condensed; Heterochromatin Repression; Condensed; Heterochromatin Repression; Condensed; Euchromatin

52. Following question # 51 above, the histone enzyme, which the affinity of DNA to histone proteins. of Pax6 in cave dwelling populations is caused by charged group to Activation; Acetyltransferase; Adds; Negatively; Acetyl; Decrease Repression; Acetyltransferase; Adds; Negatively; Acetyl; Decrease Repression; Deacetylase; Removes; Negatively; Acetyl; Increase Activation; Deacetylase; Removes; Positively; Methyl; Increase Repression; Methyltransferase; Adds; Positvely; Acetyl; Decrease
