Although it is relatively easy to visualize the components of cells, it is difficult to conceptualize how these components function Cell Analogy: Cell as Factory1) Nucleus: is comparable to the headquarters of a factory where managers will give timely instruction for the smooth running of the Created Date12/11/2019 6:49:25 PM Like any other developmental process, the cell division cycle is successful if the underlying steps take place in the right order [3]. They are similar to brakes on a car because brakes are used to slow down the car similarly to how tumor suppressing genes slow down cell To continue with the analogy: if the book you’d photocopied was a cookbook, the protein might be the food you cooked from the recipe. At its core, the cell cycle is Generate an analogy to describe the cell as the simplest unit of life to somebody who has not studied biology. The lock and key analogy is commonly used to describe the specificity of enzyme-substrate interactions. Cells do something similar when they replicate, or copy, their DNA. Cell replication regulation is often compared to a city's traffic control system. Replication begins at many origins scattered along Question: (4 points) We used an analogy in class that when cell cycle regulation gets out of control, resulting in a cancer, that it is like a speeding car-it can happen by the accelerator getting stuck, or Eukaryotic DNA replication is regulated to ensure all chromosomes replicate once and only once per cell cycle. The strands of the double-helix are separated, and two new strands are constructed by S DNA replication occurs G2 The cell prepares for cell division with the appearance of centrosomes M mitosis and cytokinesis occurs Some cells, like mature nerve cells or muscle cells, do not divide. Again keeping with the similarity to the centromere, this metaphor also has been used to describe the building of the kinetochore on the centromere (56). Study with Quizlet and memorize flashcards containing terms like cell division is important for unicellular (single-celled) organisms because, Using the brake pedal analogy, explain the impact on the cell We would like to show you a description here but the site won’t allow us. Biochemical signals act like traffic signs to manage when cells should replicate, and checkpoints help ensure this ~normal: each chromosomes loses the tip every time DNA copies itself, this limits how many times a cell can divide ~cancer: rebuild the tips of there chromosomes In all cells studied, DNA replication is regulated by recruiting the replication machinery or “replisome” to sites called origins on the chromosome (Figure 1). Proteins act as receptors, signaling molecules, and cell cycle regulators. . Except for budding Get your coupon Science Biology Biology questions and answers Use the zipper analogy to describe the basic process of DNA replication. Be sure to incorporate the observable features of living organisms, which distinguishes them Terms in this set (62) Model An analogy used by scientists, usually to describe or explain a phenomenon or process they cannot directly observe Biological Explanations brain, anatomy, For many years cell biologists watched the puppet show of DNA synthesis, mitosis, and cytokinesis but had no idea of what lay behind the curtain controlling these events. Except for budding Biotechnology Recipe Analogy The following is a good way to show the relationships among cell, nucleus, gene, chromosome, ribosome, replication, Eukaryotic DNA replication is regulated to ensure all chromosomes replicate once and only once per cell cycle. The cell-cycle control system How do proto-oncogenes and tumor suppressor genes regulate the cell cycle, and what analogy can be used to describe their roles? A team has unlocked a decades old mystery about how a critical cellular process called DNA replication is regulated. Even though this is not an exact analogy of the PCR process which will allow exponential replication of a DNA sequence, the purpose of this analogy is to The analogy "Stepping on the Accelerator" is used to describe how cell replication is regulated. Study with Quizlet and memorize flashcards containing terms like Wht did we use the analogy of 'Conducting the genetic orchestra' for the regulation of gene expression?, Define operon, trp operon The cell cycle is the name given to this sequence—a tightly regulated process that encompasses the birth, growth, division, and sometimes death of a cell. In particular, DNA replication and chromosome segregation Study with Quizlet and memorize flashcards containing terms like Using the analogy of the genome as a cookbook, what is the whole book? What is a single Figure 1. As an analogy to gene expression in Analogy - Cell Click to enlarge The cell is the basic unit of living systems. Cell items: DNA replication, Transcription, Nucleus, DNA, RNA transcript, Protein/polypeptide, Translation, RNA polymerase, Activator proteins, Ribosomes. DNA replication is semi-conservative. DNA replication is regulated in the cell cycle in Genes that prevent cell division from occurring too often. These three processes Question: How do proto-oncogenes and tumor suppressor genes regulate the cell cycle, and what analogy can be used to describe their roles?Group of answer choicesTumor suppressor genes There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which Eukaryotic DNA replication is regulated to ensure all chromosomes replicate once and only once per cell cycle. Cell replication requires intricate regulation for a cell to control its size and ensure symmetry while it The answer is: Cells receive signals through growth factors binding to receptors, initiating signaling pathways. Replication begins at many origins scattered along each chromosome. In the lock and key model, the enzyme molecule is We would like to show you a description here but the site won’t allow us.
