    who won the Nobel Prize in chemistry for his research on electrophoresis, adsorption analysis and his discoveries concerning the complex nature of serum protein. It is a technique used in laboratories in order to separate macromolecules based on molecular size and charge. • This technique applies a negative charge so proteins move towards a positive charge. This is used for both nucleic acids and proteins. Nucleic acids like DNA and RNA, while proteins

    Regulation of trp and ara operon trp operon: The trp operon is a group of genes that are used, or transcribed, together that codes for the components for production of tryptophan. The trp operon is present in many bacteria, but was first characterized in Escherichia coli. The operon is regulated so that when tryptophan synthesis are not expressed. It was an important experimental system for learning about gene regulation, and is commonly used to teach gene regulation. Discovered in 1953 by Jacques

  • Horizontal Gene Transfer In Eukaryotic Analysis

    518 Words  | 3 Pages

    In 1958, a molecular biologist named Francis Crick coined the term central dogma of molecular biology. The central dogma describes the process of how DNA is transcribed into RNA, which then get translate into proteins that is responsible for the traits expression in organisms (Crick, 1970). In eukaryotic, DNA are stores within structures known as chromosomes, which are inherited from the parental organisms, this process is known as vertical gene transfer. In contrast, bacteria can undergo horizontal

  • Regeneration In Biology

    1276 Words  | 6 Pages

    In biology, regeneration is the process of renewal, restoration, and growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.[1] Every species is capable of regeneration, from bacteria to humans.[2][3] Regeneration can either be complete[4] where the new tissue is the same as the lost tissue,[4] or incomplete[5] where after the necrotic tissue comes fibrosis.[5] At its most elementary level, regeneration is mediated

  • Forensic Entomological Analysis

    639 Words  | 3 Pages

    There are a variety of widely practiced molecular genotyping used in a forensic entomological investigation, which can be beneficial when it comes to using DNA-based specimen identification, as well as the identification of insect gut contents, and the characterization of the population of genetic structure of forensically insect species. As with most of the live sciences, forensic entomology increasingly uses the tools of molecular biology with the impact of attracting researches and performing

  • Myrtle Rust Fungus

    program was initiated by the Australian government, which conducted surveys in NSW in 2010, the data collected from the surveys shows that the fungus has already been recorded on 107 host species in 30 genera. Understanding the genome: Advanced molecular biology techniques

  • Polymerase Chain Reaction Process

    906 Words  | 4 Pages

    The polymerase chain reaction or known as (PCR) is a scientific technique used in molecular biology to amplify a specific DNA sequence.It can be used very quickly and efficiently to produce millions or billions of copies of single DNA sequence. Polymerase chain reaction or PCR uses repeated cycles of heating and cooling to make the copies of specific DNA. High temperature is necessary to break weak hydrogen bond that binds the two stands of DNA together and as a result multiple copies of a

  • Drosophila Melanogaster In The Fruit Flies

    366 Words  | 2 Pages

    From the primary literature, briefly summarize two studies that have used Drosophila as a model organism in a genetic or evolutionary context (Twenty Five Marks). The aggressive behaviour of the Fruit flies (Drosophila melanogaster) have been observed in a study to see the reaction of various neurobiological factors. Several techniques are used in the study including behavioural and genetic techniques. In the brain of the Drosophila melanogaster, neurotransmitters dopamine and octopamine as well

  • Dot Blot Analysis

    The technique is often used in research to detect specific proteins which have extracted from cells. In this process, a mixture of proteins separated based on two distinguishing properties which are molecular weight and antibody binding specificity. According to the procedure, proteins first separated based on size which have to perform with SDS-PAGE. Next, the proteins from the gel are then transferred to a polymer membrane (PVDF or nitrocellulose) to

    to amplify a DNA (Templeton, 1992). Later on in 1985, Kary B. Mullis invented the Polymerase Chain Reaction (PCR) which is used today in different fields, such as scientific research, clinical diagnostics and criminal investigations. PCR is a molecular biology tool that is used to amplify a fragment of DNA to generate thousands to millions of copies. This technique is based on an enzymatic reaction which is controlled by thermal cycling, where every cycle consists of heating and cooling steps. The
