QUESTION 22 1. In this hypothetical Xenopus (frog) experiment, nodal protein secretion has been disabled. Based on what you know about the Pitx2 gene, which of the below treatments would be the most appropriate theoretical artificial pathway to proper internal organ organization? Introduction of Nodal protein globally on the embryo. Nodal protein will not affect internal organ organization because bilateral symmetry is controlled by Shh (Sonic Hedgehog). Regional internal delivery of Nodal protein to simulate paracrine delivery. Topical integration of Nodal protein into the ectoderm.

QUESTION NO. 1 Much of procollagen formation occurs in the endoplasmic reticulum and Golgi apparatus which requires signal peptide. All of the following statements about targeting a protein for the ER are true except A. signal peptide usually has a positively charged N-terminus and a stretch of hydrophobic amino acids. B. signal peptide emerging from a free ribosome binds signal recognition particle (SRP). C. signal peptide is usually cleaved from the protein before the protein is inserted into the ER membrane. D. docking protein is actually an SRP receptor and serves to bind the SRP to the ER. E. SRP and docking protein do not enter the ER lumen but are recycledQUESTION NO. 2 All of the following statements about telomerase are correct except A. the RNA component acts as a template for the synthesis of a segment of DNA.

Question 1. Suppose that the diagram below represents the genomic organization of an enzyme involved in eye pigment production in mice. Within the gene are four exons. Biochemical analysis has revealed that the active site of the enzyme is located in the C terminus of the protein. The nucleotide length of each exon and intron is shown. The dinucleotide sequence GT represents the 5’ splice site and the dinucleotide sequence AG represents the 3’ splice site. Both the 5’ and the 3’ splice sites must be present for splicing to occur. Assume that the first and second stop codons are located immediately after the first and second 5’ splice sites, respectively; the third and fourth stop codons are located near the 3’ end of exons 3 and 4, respectively; all these stop codons are in the correct reading frame. E) Suppose you isolate a mutant mouse that has white eyes. When you examine the size of the eye pigment enzyme produced by this mouse, you see that it is 400 amino acids long. Sequence…
