5. A new mutation that arose in one copy of gene X in a somatic cell resulted in the formation of a tumor. Which of the following pieces of evidence best describes how the new mutation directly caused the tumor? (A) Protein X normally stimulates cell division, and the mutation created an overactive version of protein X. (B) Protein X normally activates a growth hormone receptor, and the mutation decreased the stability of protein X. (C) Protein X normally prevents passage through the cell cycle, and the mutation created an overactive version of protein X. (D) Protein X normally regulates gene expression, and the mutation created an underactive version of protein X that blocked the cell cycle.

(46) A mutated form of protein p5x is found in patients with squamous cell carcinoma. In vitro studies show that the normal p5x molecule binds to DNA, and neoplastic cells accumulate in the G0 phase of the cell cycle. In contrast, the mutated form of p5x does not bin d to DNA. These finding are most characteristics of which of the following? (A) Growht factor receptors (B) GTP-binding protein (C) Nonreceptor tyrosine kinases (D) Oncogene proteins (E) Tumor suppressor gene proteins

10. Protein expression can be blocked by antisense oligonucleotides. Which mechanism enables antisense oligonucleotides to block protein synthesis? O Antisense oligonucleotides bind to ribosomes and inhibit their function. Antisense oligonucleotides bind to DNA in the nucleus and inhibit the synthesis o MRNA. Antisense oligonucleotides bind to ribosomal RNA (rRNA) and inhibit ribosome assembly. Antisense oligonucleotides bind to messenger RNA (MRNA) and prevents mRNA binding to ribosomes.

I. The retinoic acid receptor (RAR) is a transcription factor that is similar to steroid hormone receptors. Thesubstance (ligand) that binds to this receptor is retinoicacid. One of the genes whose transcription is activatedby retinoic acid binding to the receptor is myoD. Thediagram that follows shows a schematic view of theRAR proteins produced by genes into which one oftwo different 12-base double-stranded oligonucleotides had been inserted in the ORF. The insertion site(a–m) associated with each mutant protein is indicatedwith the appropriate letter on the polypeptide map.For constructs encoding proteins a–e, oligonucleotide 1(5′ TTAATTAATTAA 3′ read off either strand) wasinserted into the RAR gene. For constructs encoding proteins f–m, oligonucleotide 2 (5′ CCGGCCGGCCGG 3′)was inserted into the gene.NH2 f g h i j k l m COOHa b c d eThe wild-type RAR protein can both bind DNA and activate transcription weakly in the absence of retinoic acid(RA) and strongly in RA’s presence.
