LFNG is a protein involved in early embryonic development. A mutation prevents LFNG protein from being made in the cell when it would normally be made. Which of the following is consistent with this observation? (Choose all that apply.) The mutation is early in the coding region of the LFNG gene and creates a very early STOP codon. The mutation is in a silencer of the LFPNG gene and prevents the silencer's normal function. The mutation is in the gene for a regulatory transcription factor for the LFNG gene and prevents the transcription factor's normal function. The mutation is in an enhancer of the LFNG gene and prevents the enhancer's normal function.

A mutation in the Pitx1 gene prevents development of pelvic spines in stickleback fish. Analyses of the presence and length of the gene, its mRNA transcript in pelvic tissues, and the protein produced in pelvic tissues show the following results: DNA sequence: normal length mRNA: none protein: none Which of the following is the most likely explanation for the mutation? a. It is a mutation in an enhancer region of Pitx1 that prevents a transcription factor from binding. b. It is a nonsense mutation in the Pitx1 coding region that changes a codon for an amino acid into a stop codon. c. It is a missense mutation in the Pitx1 coding region that changes a single amino acid. d. It is a mutation that deletes the entire Pitx1 gene.

A particular transcription factor binds to enhancers in 40 different genes. Predict the phenotype of individuals homozygous for a frameshift mutation in the coding sequence of the gene that specifies this transcription factor.
Mutations in the IL2RG gene cause approximately 30 percent of severe combined immunodeficiency disorder (SCID) cases in humans. These mutations result in alterations to a protein component of cytokine receptors that are essential for proper development of the immune system. The $I L 2 R G$ gene is composed of eight exons and contains upstream and downstream sequences that are necessary for proper transcription and translation. Below are some of the mutations observed. For each, explain its likely influence on the $I L 2 R G$ gene product (assume its length to be 375 amino acids). (a) Nonsense mutation in a coding region (b) Insertion in Exon 1, causing frameshift (c) Insertion in Exon $7,$ causing frameshift (d) Missense mutation (e) Deletion in Exon 2 , causing frameshift (f) Deletion in Exon 2, in frame (g) Large deletion covering Exons 2 and 3
