The Methods and Effects of Gene Therapy Concerning Cancer Lindsay Adams Abstract It has been proposed that gene therapy could yield to future treatment of cancers and other diseases and genetic disorders. Various literature sites have expressed that gene therapy is currently only used in research studies‚ and is still very young and unpredictable in clinical studies. Gene therapy has become more and more applicable to current and future medical studies concerning the treatment of cancer. The

GENE THERAPY Gene therapy is based on the concept that genetic disorders and acquired diseases can be treated by replacing abnormal or absent genes or by modifying their functions. Inherited disorders such as cystic fibrosis and haemophilia‚ as well as catastrophic diseases such as cancer and AIDS‚ are prospective candidates for gene therapy. Although cures for these ailments would be welcome‚ some medical researchers suggest that the range of diseases that can be treated with gene therapy may be

Unit 1: Biochemistry Review Chemical Bonding Three types of bonds Ionic bond: 2 oppositely charged atoms (Na and Cl) Polar covalent: Unequally shared electrons (H and O) Non polar covalent: Equally shared electrons (C and C) or similar electronegativity Electronegativity and chemical bonding Electronegativity is a measure of the strength in which an atom can attract electrons. A difference of < 0. 5 is non polar covalent bond A difference of 0.5 – 1.7 is polar covalent bond A difference of > 1
