  • Protein Synthesis Lab Report

    between eukaryotes and prokaryotes leads to dissimilar processes of protein synthesis. The larger eukaryotes have a more intricate pathway associated with protein synthesis, due to both the biochemical structure of organelles and enzymes, and also the transport of genetic material within cell. In this essay I hope to explore the differences of gene expression between these two types of cells. A key difference between Eukaryotes and Prokaryotes is that Eukaryotes contain monocistronic mRNA molecules, meaning that the molecule will only code for cistron, and henceforth one protein. Conversely, Prokaryotic mRNA is polycistronic. This means that one mRNA molecule codes for multiple cistrons, resulting in the production of many proteins upon translation. Proteins produced from this polycistronic mRNA will likely have related function, for example each cistron may code for the subunits of the quaternary structure of a globular protein. Eukaryotes contain non coding sequences within their DNA known as introns, while these are absent in Prokaryotes. In order for translation to form the correct sequence for the corresponding polypeptide, eukaryotic mRNA introns must be spliced using a collective…

  • Systemic Lupus Erythematosus Essay

    Mok & Lau (2003) explain the pathophysiology as Defective immune regulatory mechanisms, such as the clearance of apoptotic cells and immune complexes, are important contributors to the development of SLE. The loss of immune tolerance, increased antigenic load, excess T cell help, defective B cell suppression, and the shifting of T helper 1 (Th1) to Th2 immune responses leads to B cell hyperactivity and the production of pathogenic autoantibodies. Systemic lupus erythematosus (SLE) is a…

  • Rna Synthesis Essay

    University of Glasgow and Dr. Pedra Hojkova in MRC Clinical Sciences Centre, Imperial College London who will provide me Hira-flox, Cabin1-flox, Ubn1-flox (molecules of Hira complex) and Zp3-Cre mouse line (oocyte-specific Cre recombinase) respectively. Both collaborators are working on H3.3 but in different context and therefore we will not compete with each other. 1.1 Characterise the phenotypes of Cabin1 and Ubn1 oocyte specific mutants I will breed each flox line to Zp3-cre mice for…

  • Allen Developing Mouse Brain Atlas (ADA) And

    potential experiment on humans. The terminology in this study does not allow for the layman to understand it. Outside research for the use of bag-of-words technique was needed as well as other areas of the study. Ninness 's (2012) study was reliable but used a smaller subject based. Had this study been done using one dataset would have made the study more generalized. This study was easier to understand and broke down the areas a bit better than the Zeng (2015) study. There is no comparison…

  • Cell Membrane: The Two Main Components Of Cells

    INTRODUCTION TO THE CELL The cell is defined as the smallest unit of life. It is originated from a Latin word cella meaning ‘small room’ a word used by Hooke (in the year 1665 while observing a cell with the microscope he built by himself) to describe the cells. The cell is considered as a living thing because it has the ability to metabolize, grow and reproduce. Before the invention of microscope, it was difficult to talk about cells as they were tiny and so not visible with the naked eyes but…

  • Prokaryotic And Eukaryotic Cells Essay

    Cell membrane- A cell membrane is a fine structure that can also be referred to as a plasma membrane. Both Eukaryotic and prokaryotic cells are enclosed by a cell membrane. The functions are to keep a steady shape of the cell and to control particles moving into and out of the cell. These particles may be ions or molecules. Cell wall- Prokaryotic cells have a cell wall whereas eukaryotic cells don’t. The cell wall is what provides shape and protects the cell components. Nucleus- Nucleus is only…

  • Importance Of The Nucleolus Using Raman Micropectroscopy

    Gene expression within a eukaryotic cell is directly impacted by the spatial organization of the nucleus [1]. Cellular organization is carried out at the chromosome-level [1], through means of chromosome folding, gene kissing, looping, nuclear lamina associations and protein-nucleic acid interactions within nuclear bodies. Observation of the nucleolus using Raman microspectroscopy may provide more insight into macromolecule density and distribution, as well as provide answers to the still…

  • Nucleus Research Paper

    Nucleus In each cell, there is one nucleus. It is in the center of the cell, and takes up about ten percent of the cell’s volume. It is a large, oval-shaped structure bound by a double membrane called the nuclear envelope. Inside the nucleus, are organelles called nucleoli, which assemble RNA and synthesize ribosomal subunits. Throughout the inside of the nucleus, is a substance called the nucleoplasm, which suspends the nucleus’ structures. The nucleus controls the activities of the cell to…

  • Organelle Failure Research Paper

    Organelle Failure Nucleus: The nucleus of a cell is, without doubt, one of the most important parts of the cell. The nucleus instructs every single part of the cell what to do, and what the different organelles need to do. The nucleus includes chromatin (protein and DNA). It also contains Nucleolus (nucleoli is plural). These nucleoli are responsible for ribosome production. If the nucleus were to suddenly malfunction, this would mean that the cell would have no directions, and nothing to…

  • Cloning Technology

    Technology today now allows us to address the idea of cloning. Cloning is creating an identical genetic copy of an organism or a cell. The process of this is there will be three subjects A, B, and C a body cell will be taken from A, the DNA will be extracted then an egg cell will be taken from B the nucleus removed. The DNA from A is fuse with the egg cell from B the fused cell develops into an embryo when it is placed in C the surrogate and then the clone is of subject A. To get to cloning…
