In a eukaryotic cell, the hydrophilic ligand CUE binds the enzyme-linked receptor CUE receptor. Describe a realistic signal transduction cascade, that eventually leads to the transcription of the GRAD gene. The GRAD protein is secreted by the cell. Describe the critical steps in gene transcription, RNA processing and in translation, and which structures and organelles are involved. Include: organelles involved, transcription factors, amplification, RNA polymerase, a signal transduction cascade, ribosomes, how the signal reaches the nucleus, secretion from the cell and transcription factors.

In a eukaryotic cell, the hydrophilic ligand CUE binds the enzyme-linked receptor CUE receptor. Describe a hypothetical but realistic signal transduction cascade, that eventually leads to the transcription of the GRAD gene. The GRAD protein is secreted by the cell. Describe the critical steps in gene transcription, RNA processing and in translation, and which structures and organelles are involved. A detailed description of transcription and translation, and all proteins involved, is NOT expected, but a description of the main steps...

3. Prokaryotic and eukaryotic gene expression compared. Below is an incomplete table of prokaryotic and eukaryotic gene expression in comparison. Fill in the blank using PPT slides, notes and the textbook. Prokaryotic gene expression Eukaryotic gene expression Overview Steps Transcription and translation Yes Transcription and translation coupled? Gene structure No introns Epigenetic modification (chromosome remodeling) transcription, translation, RNA processing, protein processing Transcription in the nucleus and translation in the cytoplasm Interrupted gene with exons and introns RNAPI, II, III Which...
Part A What are three observations that suggested eukaryotic RNA was an intermediate between DNA and protein? Select the three observations. O DNA plays the major role in replication, which allows for sustainable transfer of genetic information. O RNA is transported out of the nucleus and into the cytoplasm where protein translation occurs. Three types of RNA are found in the cell, and all of them are involved in protein synthesis. O DNA is found in the nucleus and protein...

Last guy got it wrong - Thank you.
2. You discover a signal transduction pathway that regulates actin polymerization. SigC is the ligand, which binds to and activates a receptor tyrosine kinase (RTK). Activation of the RTK leads to the activation of the Ras protein, which then activates the protein kinase PK1 that phosphorylates the RingA protein on S34. When SigC plasma membrane phosphorylated, RingA binds EXTRACELLULAR to the gene regulatory SPACE inactive Ras protein activated Ras protein protein, AP1....
For the next group of questions consider a diploid cell from a eukaryotic organism with a total of ten chromosomes. After one round of the cell cycle is complete you observe a total of four daughter cells. During this cell division occurred and the resulting daughter cells are. mitosis; haploid with ten total chromosomes each mitosis; diploid with five total chromosomes each meiosis; diploid with ten total chromosomes each meiosis; haploid with five total chromosomes each Before the cell divided,...
