1. Your colleague is running an experiment on cell cycle. He grows cells in three conditions: control, addition of chemical X (which induces cell division), and addition of a chemical Y (which disrupts formation of microtubules). He adds each condition to a different microscope slide and stains the cells with fluorescent reagents to highlight the DNA. Only after he is done, he realizes that he forgot to label the slides! Below is a graph of the results he collected from each slide. To which experimental condition (control, Chemical X, or chemical Y) does each slide correspond to? Explain your rationale.

1. (a) Describe the generalized model of the cell cycle. Demonstrate how cyclins and cyclin-dependent kinases can regulate the cell cycle. (b). Describe three ways in which cells lose their ability to regulate their growth to become cancerous.

I need help with a biology question, thanks Match the following: Chromosomes are visible under the microscope during __________. Replication of the DNA occurs in the _____________ phase of the cell cycle. Preparations for genome separation are made in the __________ phase. The first part of Interphase Two daughter cells are formed paired with............... (Cytokinesis, S-synthesis phase, G1-gap one phase, G2-gap two phase, M-mitosis)

Cell A is actively engaging in growth and division. The cell encounters a damage in its DNA at a certain point in the cell cycle. What would be the reaction in the cells if the damage was sensed Before the R point is passed After passing the R point What would be the similarities and differences in the reaction in the cell in cases a and b? In your answer, briefly include the significance of the R point during the cell cycle

Cell Cycle: Mitosis The Cell Cycle and Mitosis Mitosis Worksheet The diagram below shows six cells in various phases of the cell evele. Note the cells are not arranged in the order in which mitosis occurs . Use the diagram to answer questions 1-5 Phases of the Cell Cycle D F 1. How can you tell which diagram(s) is/are the end of the cell division? 2. What are structures seen inside the nucleus? 3. Are the cells depicted plant or animal cells? Explain your answer.

Using a Venn diagram, compare and contrast DNA replication and DNA transcription. Make sure to include when they occur in the cell cycle and what they produce.

8) There is a photo below, where you can see dividing cells near the tip of an onion root under the light microscope, identify a cell in each of the following stages by circling: Metaphase, Anaphase, and Cytokinesis.

Which of the following is true of normal adult cells but NOT cancer cells? A. Cell death after a finite number of cell divisions B. Contact with other cells increases likelihood of division C. Large amount of telomerase present D. Do not care about cell density while culture

3.12) Draw, label and explain what is happening to the chromosomes, cytoskeleton and membranes at each stage of mitosis and interphase. To demonstrate deep thinking you should represent the mechanisms of each step and why the steps have to be in the order then are in because of the mechanisms. A design justification (a short paragraph) A description of how the work demonstrates your deep thinking (a short paragraph) A description of how you are using constructive feedback for continuous improvement, and giving constructive feedback to others (a short paragraph) The creation itself (or a representation of it)  asap please answer all

Can you help me fill in the graph below? This is a whitefish blastula cell and I have to fill in a time for each phase.
