Which of the following is NOT true about the mechanics of cellular circadian clocks? 1. Timeless gene encodes for TIM, which is the master clock regulator by destableizing the PER protein each morning 2. CLK and CYC regulate the transcription of the Period gene 3. Doubletime (DBT) delays the accumulation of the PER protein in the cytoplasm 4. The CRY protein is primarily responsible for entrainment.

Insulin-like growth factor (IGF) is a peptide hormone (ligand) that binds and activates IGF receptor tyrosine kinase. Once the ligands bind the receptors, the cell undergoes cell division and multiply. Therefore, IGF is important for the growth of muscle and bone tissues during puberty. The way the IGF hormone works is that the hormone-bound IGF receptor tyrosine kinase increases the levels of cyclins inside of the cell and promotes the progression of the cell cycle. Describe how receptor tyrosine kinase works in a general sense and how cyclins regulate the cell cycle.
Which of the following is not an internal or external factor that controls cell division? a Apoptosis is a special set of controlled steps in which a cell dies intentionally. b When a neighboring cell grows, its cell membrane is touching its neighbor. c Signal receptors on the inside of the cell membrane detect overstretching of the cell membrane when a cell gets too large. d chemical messengers like kinase and cyclin
Which of the following changes to the microtubule binding protein, Tau, commonly occurs in Alzheimerâ s and other neurodegenerative diseases? A Tau is hypo-phosphorylated and does not bind to microtubules to destabilize them. B Tau levels are so low in the cell that they only bind to some microtubules. C Tau is hyper-phosphorylated and does not bind to microtubules to stabilize them. D Microtubules are hyper-phosphorylated and do not bind to Tau.
Which of the following can be correctly deduced from the figure? Gj checkpoint- Souree Jane Reece, et al. Campbell Eiolagy Ninth Edituort. (San Francisco, California Pearson Henjamia The cell cycle control system proceeds on its own, driven by a built-in clock. This control system is subject to internal and external regulation at various checkpoints If a cell receives a go-ahead signal at the G1 checkpoint, the cell continues on in the cell cycle. If a cell does not receive a go-ahead signal at the Gl checkpoint, the cell continues on in cell cycle and goes into Go, a nondividing state. G1 is the restriction point. A. I, II and III B. I, II, and Iv C. I1, III, and IV D. I, II, III, and IV 1. II. III. IV. Which of the following is the correct sequence on the phases of mitosis? A. S-Phase, Metaphase, Interphase, Telophase B. Prophase, Metaphase, Anaphase, Telophase C. Prophase, Metaphase, Interphase, Telophase D. Interphase, Prophase, Metaphase, Telophase Which of the following event…
Figure 37.5 Heat shock proteins (HSP) are so named because they help refold misfolded proteins. In response to increased temperature (a “heat shock"), heat shock proteins are activated by release from the NR/HSP complex. At the same time, transcription of HSP genes is activated. Why do you think the cell responds to a heat shock by increasing the activity of proteins that help refold misfolded proteins?
TRUE / FALSE (if false put the correct word in) Voltage-gated sodium channels open to allow the influx of positive ions to move the vesicles containing neurotransmitters in synaptic transmission. During cleavage, daughter cells become smaller and smaller as interphase consists of S phase only. The inner cell mass consists of pluripotent cells.
Some muscle cells contain several nuclei per cell. Which of the following provides the most likely explanation for the way in which these cells came to have more than one nucleus? A B с D They underwent repeated mitosis simultaneously with cytokinesis. They underwent repeated mitosis but not cytokinesis. They underwent multiple S phases before entering mitosis. They underwent repeated cytokinesis but not mitosis.
A cell picks up mutations that allow it to move past the G1 and G2 checkpoints even if its growth factor is not present, These mutations a tightly to other cells and the extracellular matrix. As a result, this cell would .. O die O form a benign tumor form a malignant tumor that metasticizes O form a mass of normal tissue
A brain scan of an epileptic patient shows that the patient has clusters of neuronal cell bodies positioned in posterior periventricular zọne. A likely cause of this mislocalization could be a mutation in some repulsive guidance molecules in the extracellular matrix. a mutation in the Sonic Hedgehog factor which inactivates its function. O a mutation in the reelin protein at the marginal zone during development. O a defect in neuroepithelial cell mitotic process. a mutation in an astrocytes plasma membrane protein.
Diagram (just use arrows in the same way you diagrammed in a former test a stimulus leading to the activation of PKC, for example) in as much detail as possible what happens to a mammalian cell when it is irradiated, leading to when the cycle stops due to DNA damage. Include and name the famous mammalian checkpoint protein known by its molecular weight, as well as name another protein it activates. This other protein's function can be described by a 3 letter acronym that contains the letter K. Mention the acronym. 1.
