- 3). Consider the four mutations (i-iv) described below: i. One of the mutations causing cystic fibrosis in humans is a deletion of three nucleotides that eliminates a phenylalanine at position 508 of the CFTR protein (D508). Normally, CFTR protein is localized to the plasma membrane, where it functions as a chloride ion channel. D508 CFTR is misfolded and all of it is degraded without ever reaching the cell surface. ii. The yeast transcription factor Gal4p contains a DNA-binding domain and a transcriptional activation domain. An allele with a deletion the gene portion encoding the activation domain encodes a truncated Gal4p containing only the DNA-binding domain. It binds to Gal4p target genes at appropriate binding sites in their upstream regulatory regions, but does not activate their transcription. In cells with both wild type and mutant forms of Gal4p, the truncated Gal4p binds more efficiently to target DNA sequences than wild type. iii. Mutations in the acid maltase gene in…Point mutations in multiple tumor suppressor proteins have been linked to cancer. For example changes in the gene for adenomatous-polyposis-coli protein (APC gene) may result in colorectal cancer. Consider the following DNA sense strand. 3'-TAC CGG TTG TGA AGC TGA ATC-5' (i) (ii) (iii) (iv) Derive the mRNA molecule from the given DNA strand sequence above, paying attention to the polarity of the molecule. Write down the polypeptide chain sequence arising from the mRNA molecule of the question above, using the table of the genetic code (Table Q1 overleaf) and indicate the C- and the N-terminus of the peptide chain. Point mutations of a cytosine (C) often lead to the dysfunction of the APC protein. Write down all possible polypeptide chains that can result from all possible DNA mutations of cytosines, disregarding a mutation in the MET/START and STOP codons. I Specify which of the point mutations identified in (d) are redundant?Which of the following statements most accurately represent chromatin state and transcription? Group of answer choices 1.Histone deacetylases promote closed chromatin and result in repressed transcription 2.Open chromatin is associated with hypoacetylation and has high levels of transcription 3.Histone acetyltransferases result in hypoacetylation and high levels of transcription 4.Hyperacetylation is associated with closed chromatin and low levels of transcription
- In diseases such as Creutzfeldt-Jakob disease (CJD), a normal prion protein becomes infectious and transforms other proteins. The "normal" protein and the "infectious" " prion protein are identical in primary structure; that is they are both composed of the same amino acids in the same sequence. What could identify the abnormal protein? 1. The difference could be that the "infectious" protein has undergone a repeated packaging by the Golgi apparatus. 2. The difference could be that the protein has become infected by a bacterium 3. The difference could be that the protein has mutated 4. The difference could be that the "normal" protein's shape; its secondary, tertiary, or possibly quaternary structure has changed.The beginning of the hexose kinase gene's sequence can be found below, the +1 nucleotide is underlined and bolded.

A possible way this inhibition may be relieved by an sRNA would be: Group of answer choices 1.The sRNA acts as a marker, flagging the inhibitory protein for ubiquitination and allowing translation to take place. 2.The sRNA acts as a decoy, sequestering the inhibitory protein and allowing translation to take place. 3.The sRNA acts as an enhancer, suppressing the inhibitory protein and allowing translation to take place. 4.The sRNA acts as a silencer, suppressing the inhibitory protein and allowing translation to take place. Which one is the correct?

- At 2:00 pm, you measured intracellular arginine at 100M. After addition of 200M of arginine to the cell, you, at 2:45 pm, measured intracellular arginine levels to be still at 100M. The most likely explanation is: Arginine bound to the active site of the repressor protein Arginine bound to the allosteric site of RNA polymerase Arginine was in excess in the cell and acted as an inducer Arginine was in excess in the cell and bound to the operator Arginine bound to the allosteric site of the repressor proteinFour terms and statements related to gene regulation in bacteria are listed below. Match the correct term to each of the four statements: Regulatory molecule that binds to operator region in DNA. 1. repressor Regulatory molecule that must be present at a site in DNA (such as promoter) so that transcription occurs. 2.
