Given the following schematic for a gene and its associated regulatory regions, answer the following questions by placing the correct letter in the provided blanks please put in the correct letter for the questions What region would provide cell type-specific expression of genes? region What site would significantly increase gene expression rates? = region What region or regions of this gene’s coding sequence are expressed as amino acids = region
Like Hurler syndrome, Fabry disease involves an abnormal accumulationof substances within lysosomes. However, the lysosomesof individuals with Fabry disease show an abnormal accumulationof lipids. The defective enzyme is α-galactosidase A, which is alysosomal enzyme that functions in lipid metabolism. The enzymaticdefect causes cell damage, especially to the kidneys, heart,and eyes. The gene that encodes α-galactosidase A is found on theX chromosome. Let’s suppose a phenotypically unaffected coupleproduces two sons with Fabry disease and one phenotypicallyunaffected daughter. What is the probability that the daughter willhave an affected son?
The protein known as tyrosinase is needed to make certain types of pigments. Tyrosinase is composed of a single polypeptide with 511amino acids. The molecular mass of this protein is approximately61,300 Da, or 61.3 kDa. People who carry two defective copies ofthe tyrosinase gene have the condition known as albinism. They areunable to make pigment in the skin, eyes, and hair. Western blottingis used to detect proteins that are translated from a particularmRNA. This method is described in Chapter 20 and also in experimentalquestion E4. Skin samples were collected from a pigmentedindividual (lane 1) and from three unrelated albino individuals(lanes 2, 3, and 4) and subjected to a Western blot analysis using anantibody that recognizes tyrosinase.
The process of gene expression involves:
Choose the statement that correctly characterizes regulated and/or constitutive gene expression. Regulated expression refers to gene expression that is either on or off, depending on the physiological or metabolic status of the cell. Constitutive expression refers to gene expression that is either on or off, depending on the physiological or metabolic status of the cell. Constitutive expression refers to gene expression that is always repressed in response to the absence of required nutrients or other metabolic molecules. Regulated expression refers to gene expression that is always on, regardless of the metabolic or physiological conditions in the cell. Regulated and constitutive expression are terms used to describe gene expression in prokaryotes only.
DNA and RNA are information molecules with different roles in gene expression. List three differences between these two types of molecules.
What role do the following cellular components play in thestorage, expression, or transmission of genetic information: nucleolus
Describe missense and nonsense mutations and how they are different from frameshift mutations. Be comprehensive and tailor your answer to explain the impact of these mutations on the protein expressed
Hydrogen bonds are important in DNA replication and transcription. They are relatively weak chemical bonds. Why is this a desirable feature for DNA? Describe the effect (s) of changing (mutating) the promoter on the transcription of the DNA strand/gene the promoter controls. What happens to protein synthesis if a nonsense codon is inserted into the gene? Explain why a point mutation does not necessarily change the original amino acid sequence. (Explain silent mutations) Choose any pentapeptide composed of five different amino acids. List the amino acids. Present one messenger RNA codon for each amino acids and the sequence of nucleotides on the DNA that originally coded for your pentapeptide.
Which of the following statament is NOT TRUE about gene expression? Lüffen birini seçin: O a. Gene expression is the process by which DNA directs the synthesis of proteins O b. During gene expression, the information encoded in genes is used to make specific polypeptide chains or RNA molecules. O c. The expression of genes that code for proteins includes two stages: replication and translation O d. Translation is the synthesis of a polypeptide using the information in the MRNA.
Heritable effects of gene expression that are not caused by a change in DNA sequence are called epigenic changes. What causes these changes?
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.
