  • RNA Polymerases

    “However, the DNA-dependent RNA polymerase proved elusive until 1960, when it was independently identified in bacteria by Hurwitz and Stevens and in plants by the Bonner group” (p. 8325). There were also many experiments after these in which the scientists focused mostly on the mechanisms of the RNA polymerization (Kireeva, 2013). Kireeva also stated in her article that a group called the Chamberlin group focused on the pauses by E. coli RNA polymerase the group also focused on the…

  • Ebola Virus

    joint pain, liver inflammation, and decreased hearing capabilities among other difficulties. Those who survive can no longer transmit the disease. Negative sense, single stranded RNA (ssRNA) constitutes the virus’s genome. It is considered to be a negative sense because the RNA cannot be directly translated into functional proteins. It must first be transcribed into mRNA, which is complementary to the ssRNA, before it can be translated. The ssRNA is contained in virions that are cylindrical or…

  • Difference Between Bacteria And Eukaryotes

    eukaryotes is that genetic information is formed in protein and is converted into organization, function and cellular structure. Eukaryotes also have a replication of machinery that is found in bacteria but are more complex and larger. The phase of replication has more factors for helicase and primase complexes, it then loads onto a sliding clamp unit where polymerase is there as…

  • Neoplasm Case Study

    cancer has been made evident the use in studying this circadian clock gene is quite clear and the need for a more solid grasp on its mechanism is necessary to understand a possible treatment in cancer. For this experiment we chose a knockdown experiment through RNA interference (RNAi) of the timeless gene in order to observe the phenotypic outcome in planarian when this gene is absent. This is a known procedure for disturbing the function of genes in planarian (4). We made a double stranded…

  • Protein Molecules Essay

    Proteins Molecules Building materials for cells. Cells have organelles such as mitochondria, lysosomes, vesicles, etc. It is estimated that the body has over ten trillions cells Carry oxygen, build tissue, copy DNA for the next generation and do the work needed by the body. Deoxyribonucleic acid contains the blueprint for proteins and replication of itself mRNA transcribes DNA, tRNA translates mRNA into proteins. A pattern on nucleotide on a DNA strand is called a gene. The Central Dogma of…

  • Eukaryotic Synthesis

    Transcription is considered to be the first step of gene expression. It is known to be the process of making a copy of genetic information stored in a DNA strand into a complementary strand of messenger RNA (mRNA). The process of eukaryotic transcription can be separated into three phases, initiation, elongation and termination. This complex process involves various cell signaling methods as well as the activity of many enzymes. Genes are segments of DNA nucleotides located on a chromosome…

  • Central Dogma Of Molecular Biology

    Possible Modifications of Central Dogma of molecular Biology Introduction The central dogma of molecular biology is describes the transfer of genetic information within a biological system and was first stated by Francis Crick in 1956. The central dogma is the flow of genetic information as ‘’DNA makes the RNA and RNA makes the protein.’’All biological cells with few exceptions in some follow this rule. This flow takes place through three fundamental processes: replication, transcription and…

  • Protein Synthesis Paper

    This paper is going to describe the replication of DNA and RNA and the processes of transcription and translation of protein synthesis. What is DNA? DNA is a nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes,…

  • Lujo Virus Essay

    a. Introduction Lujo Hemorrhagic Fever is caused by a bi-segmented negative RNA virus that is one of several viruses known to cause viral hemorrhagic fever. The Lujo virus is part of the Arenaviridae family, which consist of several viruses categorized into two groups. The Lujo virus is categorized in the “Old World” group, which signifies that the virus in question was found in the Eastern Hemisphere, specifically the continent of Africa. The majority of the arenaviruses categorized in the…

  • Proteins: Large, Complex Macromolecules In Organisms

    The ribosome reads information along the mRNA and brings the amino acid together with help from transfer RNA. Transfer RNA has a cloverleaf shape with base-paired arms and an attached anticodon sequence. At the bottom of the tRNA there is an anticodon that pairs with a codon on mRNA. A codon is a sequence of three nucleotides. Codons are read, in order, by tRNA, which aligns with the codon and attracts the corresponding amino acid. It continues this same cycle, connecting amino acids, to make a…
