EpothiloneB: binds to b-tubulin and prevents depolymerization Many chemotherapeutic drugs target microtubules and microfilaments. Two drugs are listed below. One affects microtubules and one affects microfilaments. These drugs ACT ON THE NORMAL PROCESSES of cytoskeletal dynamics. Use your understanding of these processes to postulate on how the drug achieves its effect! Given the effect of the drug what stage or stages of the cell cycle might be affected by this drug? Explain your reasoning
2. How is ATP used in most cell processes? a. It binds to a substrate and provides energy when the phosphate group is released. b. indirectly, by providing electrons to an acceptor c. Hydrolysis of ATP is coupled to an endergonic reaction. d. It increases the efficiency of some key enzymes. e. none of the above 2. How is ATP used in most cell processes? a.

Question 1 Not yet answered Consider the following western blot for tubulin. Each lane represents a different cell line culture. What can be concluded from this blot? Points out of 2.50 P Flag question 191 97 64- 51 -B-Tubulin 39 28 19- Select one: a. Tubulins from different organisms vary in size O b. More than one statement can be concluded from this western blot c. Tubulin is expressed in all cell lines tested O d. The primary antibody used...
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...
How is the orientation of cell division related to cell fate / cell lineage in C. elegans?
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...
1. Describe how normal cellular processes (cell division and metabolism) contribute to aging. 2. Why are aging-related diseases, such as Alzheimer's, Parkinson's, cataracts, arthritis, osteoporosis, and cancer, becoming so common in the modern era?

Question 5 The term apoptosis means: 1-Cell death 2-Cell division 3-Cell growth 4-Cell metabolism
QUESTION 2: What are three kinds of cell division? What are the products of (# of cells and genetic makeup) of each? In what situations are they used? - 3 kind of cell division= Mitosis, meiosis, and binary fission I'm having a hard time answering the second and third part of the question. Please help!
