What is a second messenger? What are two second messengers that are involved in signaling pathways downstream of GPCRs and explain how they are produced?
long answer: If you wanted to compare a cardiac muscle cell with a skeletal muscle, how could you use RNA sequencing to identify genes that are differentially expressed? In your answer, explain this technique and describe what type of information you can learn from it. If RNA sequencing led to the identification of two genes, gene X and gene Y, what are two experiments you could do to study the functions of these two genes?

- Part A and B A. What below would be likely to lead to cancer development? A) Overexpression of a cell cycle checkpoint inhibitor B) Loss of expression of a growth factor that promotes cell cycle entry C) Overexpression of a receptor tyrosine kinase that promotes cell cycle entry D) Overexpression of a DNA damage repair enzyme E) Loss of expression of a regulatory transcription factor that activates transcription of a cyclin B. Taxols inhibit the proper function of microtubules and are frequently used as chemotherapy drugs. What is the function of microtubules during the cell cycle? A) They promote the G1 to S checkpoint B) They normally inhibit M phase from being completed C) They form the mitotic spindle E) They mediate DNA replication F) They form the cleavage furrow during cytokinesisarrow_forwardThe number and complexity of gene families linked with cell adhesion and cell signaling pathways has increased during many of the distinct transitions to multicellularity. Why would this be the case? Why is it unexpected that the emergence of multicellularity is frequently associated with an increase in gene families connected with cell–cell signaling?arrow_forwardAlmost all cells within an animal contain DNA with the same sequence, yet different cells can have very different properties and gene expression patterns. What are the primary mechanisms that facilitate the existence of distinct cell types in eukaryotes?arrow_forward
- which of the following correctly describes how protein kinase A can activate genes? A: nuclear protein kinase A is activated by cAMP to phosphorylate general transcription factors B: cytosolic protein kinase A is activated by cAMP to release the catalytic subunits, which move into the nucleus and phosphorylate CREB C: cytosolic protein kinase A is activated by cAMP to release the catalytic subunits, which move into the nucleus and phosphorylate general transcription factors D: G protein-coupled receptors may be desensitized by serine phosphorylationarrow_forwardYou are interested in studying a novel gene that appears to be involved in cancer. There is no information about the function of this gene. What would you do to obtain the cDNA for this gene? How would you express this gene and what expression systems might you utilize to study its function and why? How would determine the subcellular localization of this gene in eukaryotic cells? What are alternative methods in case one doesn't work? How would you purify and determine the 3-dimensional structure of this protein?arrow_forwardMyc is a family of regulator genes that code for transcription factors. c-myc was the first gene to be discovered in this family, and c-myc is dependent on mitogenic stimulation for its expression and function. c-myc transcribes a number of genes involved in G1/S cell cycle progression, such as CDK4 and cdc25A Which of the following are true for the c-myc gene? Select all that apply In cancer or transformed cells, the c-myc gene mutation would be recessive, and a loss of function mutation The c-myc gene is a tumor suppressor gene In cancer or transformed cells, the c-myc gene mutation would be dominant, and a gain of function mutation The c-myc gene is a proto-oncogenearrow_forward
- Most organisms display a circadian rhythm, a cycling of biological processes that is roughly synchronized with day length. In Drosophila, pupae eclose (emerge as adults after metamorphosis) at dawn. a)Using this knowledge how would screen for Drosophila mutants that have an impaired circadian rhythm? b)In each case, how would you clone the genes you identified by mutation?arrow_forwardFor each of the following situations, provide a plausible explanation for how it could lead to unrestricted cell division.(a) Colon cancer cells often contain mutations in the gene encoding the prostaglandin E2 receptor. PGE2 is a growth factor required for the division of cells in the gastrointestinal tract.(b) Kaposi sarcoma, a common tumor in people with untreated AIDS, is caused by a virus carrying a gene for a protein similar to the chemokine receptors CXCR1 and CXCR2. Chemokines are cell-specific growth factors.(c) Adenovirus, a tumor virus, carries a gene for the protein E1A, which binds to the retinoblastoma protein, pRb. (d) An important feature of many oncogenes and tumor suppressor genes is their celltype specificity. For example, mutations in the PGE2 receptor are not typically found in lung tumors. Explain this observation. (Note that PGE2 acts through a GPCR in the plasma membrane.)arrow_forwardWhat kind of response is seen via temperature stress in Drosophila? Are these kinds of elements conserved in all organisms? What is the role of the final protein element translated?arrow_forward

Phosphorylation of BETA at the amino acid Tyr98 causes BETA to be degraded by the proteasome, thus limiting its abundance. A mutation in the codon encoding Tyr98 changes this residue to Cys, which cannot be phosphorylated. What is the best description of this mutant allele?a) antimorphb) hypermorphc) hypomorphd) amorphe) neomorpharrow_forward
