  • Polymerase Chain Reaction And Gene Therapy

    The role of polymerase chain reaction(PCR) and Gene therapy in medicine. PCR was developed by Kary Mullis in the 1980s. It is a method in which a single copy of DNA is amplified. Using this technique which has a specific sequences ,millions of copies of DNA can be produced. In this process, many other conditions including several enzymes and primers are involved. This application of PCR extent from research to the commercial sector. Denaturation:- The reaction mixture is heated up to…

  • Peptidomimetics Essay

    same biological effect. The demand for modified peptides with improved stability profiles and pharmacokinetic properties is driving extensive research effort in this field. Many structural modifications of peptides guided by rational design and molecular modeling have been established to develop novel synthetic approaches. A significant impact of structure-based drug design has emerged over recent years in the discovery of novel peptidomimetics and nonpeptides. Such reesearch has been catalyzed…

  • Dna Recombination In Genetic Engineering

    Abstract DNA recombination is basically generation of the new DNA sequence in genome by exchange of DNA strands. Recombination generally but not necessarily occurs between similar DNA sequences and provides genetic variation, genome integrity [1]. There are four main ways being identified to produce recombinant DNA; homologous recombination in which physical exchange of DNA sequences occur between the homologous chromosomes, illegitimate recombination occurs between DNA sequences sharing low…

  • Cytokinesis In Onion Lab Report

    Observation of mitosis in Onion root tips Answer the following question to its full explanation: 1. What is Cytokinesis? Compare and contrast cytokinesis between plant and animal cells. Cytokinesis is the last step in cell division, where the cytoplasm divide and the two daughter cells appear. In Animals, the cytokinesis processes occurs through cleavage. Firstly, in the old metaphase plate position, a cleavage furrow is formed. On each sides of the furrow, a contractile ring formed of actin…

  • What Is The Difference Between Saw1 And Pgex-Saw1 Primer

    The number of base pairs for the PGEX-KG (original) plasmid and PGEX-KG SAW1 (clone gene) is different. PGEX-KG- Saw1 has 794 bp more than original plasmid. The single digestion for both PGEX-KG and PGEX-KG-Saw1 will make a single cut in their respective restriction sites. The clone and original plasmids will become linearized and the PGEX-KG-Saw1 will be longer than PGEX-KG because of the insertion of Saw1. However, the insertion Saw1 can be isolated from the clone plasmid by doing double…

  • Dmitri Ivanovski's Leadership Style

    Dmitri Iosifovich Ivanovski (1864-1920) was a famous botanist, plant physiologist, and microbiologist (Lechevalier, 1972) who lived in Russia. He is considered one of the founders of virology. Ivanovski also did work with tobacco plants, mosaic disease, soil microbiology, and fermentation. Ivanovski’s life was very interesting. His early years were spent in a small village in Russia. In his later life he went to different universities and participated in many scientific experiments, lectures,…

  • DNA Fingerprinting In Forensic Science

    DNA Fingerprinting Introduction Background: DNA fingerprinting is one of the great discoveries of the late 20th century,that has revolutionized forensic investigations. (Roewer 2013) The complete DNA of each individual is unique, with the exception of identical twins. It is this difference that can be used by forensic scientists to match specimens of blood , tissue, or hair follicles to an individual with a high level of certainty. A DNA fingerprint, therefore, is a DNA pattern that has a…
