DNA Function and Aging Gavriel Boroosan Yeshiva Ohr Yisrael All living organisms consist of cells. Cells contain mainly internal structures and are highly complex. There are three main types of cells: archaea‚ prokaryotes‚ and eukaryotes. Prokaryotes are single celled‚ archaea are organisms often found in extreme environmental condition‚ and eukaryotes are multi-cellular organisms which include humans and animals ("Cells - Structure and Function‚" n.d.). While all types of cells contain deoxyribonucleic

DNA synthesis inhibitors Nucleic acid inhibitors are chemicals which inhibit the production of nucleic acids including both DNA and RNA. DNA and RNA inhibitors inhibit enzyme action in DNA replication in the same way as the topoisomerase inhibitors we discussed earlier. Topoisomerase inhibitors (1) (10) are chemicals which interfere with the enzymes that allow DNA strands to separate and to re-join‚ a process that is required for the division of bacteria and without which DNA cannot effectively

DNA replication: DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. The cell cycle includes interphase‚ prophase‚ metaphase‚ anaphase‚ and telophase. Each strand of the original double-stranded DNA molecule serves as template

Carl Woese Carl Woese used phylogenetic taxonomy of 16s ribosomal RNA to begin to define Archaea as a separate domain of life from eukaryotes and bacteria. It is important to note that though Woese defined the archaea in 1977 they would not be accepted as a separate domain of life from bacteria until the mid 80s. Importance of 16srRNA: 1. Universally distributed 2. Functionally homologous 3. Sequences are conserved 4. Molecule should reflect evolutionary change in organism as a whole Although

Computing Computer Science & Engineering DNA Computing Computer chip manufacturers have discovered that sooner or later the physical speed and miniaturization limits of silicon chip is bound to hit a wall‚ therefore they need a new material to produce faster computing speed with fewewr complexity. DNA‚ the material are genes are made of‚ is being used to built the next generation of microprocessor. A nascent technology that uses DNA molecules is to build computers that are faster than

DNA is the most important for life One of the most complex and mysterious aspects of contemporary science is the constitution of life. While it goes without saying there are an enormous amount of components that collaborate to achieve the most effective and efficient components of life‚ it’s also clear that some of these molecular components contribute to the actual function of living system more than others. This essay argues the DNA is the most important molecule for life. Deoxyribonucleic

DNA FINGERPRINTING Background Reading - Nelson Biology and Campbell Biology Purpose - To understand the basics of DNA fingerprinting used in the Canadian courts for crime convictions and paternity suits. Introduction The process of DNA fingerprinting was developed by Professor Alec Jeffreys at Leicester University in 1984 as a form of genetic analysis. It was first used in the law courts of England in 1987 to convict a man in a rape case. It has now been used successfully in many crime and paternity

BIOTECHNOLOGY RECOMBINANT DNA technology 1. This is a modern biotechnological advance ‚ in which a desired gene fragment can be inserted in to a cloning vector and the resulting DNA (Recombinant DNA) can be amplified in suitable host. 2. A vector can be a plasmid‚ cosmid‚bacterophage‚retroviruses‚ animal and plant viruses or artificial chromosomes like YAC‚ BAC‚or HAC.(Yeast artificial chromosome‚ bacterial........) 3. The rec. DNA produced can be amplified or cloned in a suitable vector

complexity of ourselves and of other forms of life (1). Significant developments have been made in gene monitoring techniques specifically in DNA microarrays which only very recently revolutionized genome expression analysis (1). Despite continuous improvements and modification to the technique‚ DNA microarrays are still no more than a glass microscope slide studded with individual immobile nucleotide fragments (1‚ 2). The fundamentals of DNA microarrays are set on complementary base-pairing (3)
