1 DA and rotein Synthesis - Life is a Three Letter Word! - CATER TES What is DA? DA is the control molecule of life. DA has three major functions: 1. DA CTRLS CELLULAR ACTIVITIES including reproduction. DA carries a CDE. Genetic instructions are encoded in the sequence of bases DA from male + DA from female = genetic information of offspring in sexual reproduction. DA instructions RA molecules proteins on which all forms of life are based.. DA MAKES EXACT CIES F ITSELF to pass onto other cells. RELICATI 3. DA UDERGES MUTATIS mutations and recombinations in DA molecules are the source of life's diversity. Linked to the Theory of Evolution explains all the species that have lived on this Earth. The Structure of ucleic Acids DA & RA are LYMERS of Each nucleotide is composed of: 1. a pentose (5 carbon). a group 3. a nitrogenous there are two types of bases: i) URIES - have a ring structure (adenine & guanine) - - C - - C nucleotide: base = Adenine nucleotide: base = Guanine ii) YRIMIDIES - have a ring structure (thymine, cytosine, uracil) 3 C - - C nucleotide: base = Thymine - - C nucleotide: base = Cytosine - - C eotide: base = Uracil RA LY nucl age 1

RELICATI - DA making identical copies of itself DA s structure has a natural mechanism for reproducing itself. Before a cell can divide, DA must be duplicated. This duplication process is called RELICATI. each strand of DA can be viewed as a template: like a potter's mold, it can produce a "reverse image" copy of itself (a complementary copy). Each new strand of DA produced has a sequence of bases exactly complementary to the template strand. Sequence of Events in Replication: 1. UZIIG: the DA double helix (helicase), and the two strands of DA separate; hydrogen bonds between the bases unwinding unzipping = breaking bonds 3
4 . CMLEMETARY BASE AIRIG: new nucleotides move in to pair up with bases of each strand of DA. These new nucleotides are always floating around within the nucleoplasm. 3. ADJACET UCLETIDES BD: sugarphosphate bonds form between adjacent nucleotides of the new strand to complete the molecule. The new molecule winds into a double helix. Base pairing Adjacent nucleotides bond FIAL RDUCT ew double strand of DA contains one "old" strand (the template) and one new strand. " " replication. half of the original molecule is conserved in each new molecule this ensures that there will be, replication of the parent molecule. this process proceeds by the action of several very specific (e.g. DA olymerases, gyrase, helicase) product of replication is two double-stranded DA molecules, each with one new strand and one original stand that acted as a template for replication. 4
