- The process of cell modification from a generalized cell to one that performs a specific task is known as recombinant DNA O gene expression O cell differentiation gene developmentI. 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. Each…The following is true about epigenetic gene control: O epigenetic changes to the chromatin may result from childhood development epigenetic changes to the chromatin may result from chemicals in the environment O epigenetic changes to the chromatin may result in cancer O An example of a chromatin change is DNA methylation that prevents gene expression from that area of the DNA

O Galactose increases gene expression by inhibiting Gal80 O Galactose increases gene expression by binding Gal4 O Galactose decreases gene expression by binding RNA polymerase O Gal4 binds to the promoter O Gal80 binds to the promoter
- Match each example of mutation to the correct effect on function. Hypomorphic mutation Hypermorphic mutation Antimorphic mutation Neomorphic A deletion results in the loss of part of a protein and the protein retains some of its normal activity. A mutant allele makes a protein with increased cataytic activity. A mutant form of a transcription factor binds new DNA sequences to activate different genes. A mutant from of a receptor protein interferes with the function of the wild-type receptor through heterodimerization.Control of gene expression in eukaryotic cells occurs at which level(s)? Lüffen birini seçin: a. epigenetic and transcriptional levels O b. post-transcriptional, translational, and post-translational levels O c. only the transcriptional level O d. epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels O e. epigenetic, transcriptional, and translational levelsWhich of the following proteins is a combinatorial transcriptional regulator in Drosophila that affects the differentiation of multiple cell types?

- Select the incorrect statement: O A. Transcription produces an mRNA of a gene that leaves the nucleus. O B. A hydrophobic hormone-receptor complex may increase the expression of a specific protein by stimulating the transcription of more of that protein's MRNA. OC Protein synthesis is a two-phase process that includes transcription and translation. O D, In the process of transcription, the entire chromosome is copied by RNA polymerase.You observe that a particular gene is being transcribed during development. How can you tell whether the expression of this gene is under transcriptional or translational control?Below is a model of a signal transduction pathway that results in the transcribing of mRNA: Receptor protein Transcription factor Phosphorylation cascade DNA mRNA What is the best description of what would happen if the phosphorylation cascade resulted in a phosphate being attached to the transcription factor? O mRN would not stop being transcribed from the DNA. O The phosphorylation cascade would continue to release excess phosphates. O mRNA would stop being translated from the DNA. O Receptor proteins would not bind to the signaling hormone.
