PPT-Chapter 13 DNA Technology

Genetic Engineering the application of molecular genetics for practical purposes Can be used to IDENTIFY or TRANSFER genes DNA Technology can be used to cure diseases treat genetic disorders improve food crops etc. Unless you have an identical twin, you, like the sisters in this picture will share some, but not all . characteristics . with family members. DNA. The . instructions. for inherited traits are called genes.. DNA from a few Angles. Cell: . Every cell contains a nucleus which is filled with the directions for cell function, DNA. . Chromosome. : . When DNA is tightly coiled and wound it becomes visible in the form of . “DNA is a helical structure” . with “two co-axial molecules.”. “period is 34 . Å. ” . “one repeating unit contains ten . nucleotides on each of two . . . co-axial molecules.'’. “The phosphate groups lie on the outside of the structural unit, on a helix of diameter about 20 . DNA damage DNA gets damaged a lot ! DNA damage DNA gets damaged a lot! >200,000 events/human cell/day DNA damage Occurs 2 ways 1) spontaneously 2) mutagens : damage DNA Transposons Discovered by Barbara McClintock DNA GLOW Lab A new way to investigate DNA structure. V1.1: June 2018 © Copyright by Amplyus LLC, all rights reserved We bring the study of DNA structure to your hands Patent pending DNA GLOW Lab Gene cloning and other techniques, collectively termed DNA technology, can be used to manipulate and analyze DNA and to produce useful new products and organisms.. In genetic engineering, bacterial restriction enzymes are used to cut DNA molecules within short, specific nucleotide sequences (restriction sites), yielding a set of double-stranded DNA fragments with single stranded sticky ends..  . 5 marks. Question 1 - Answers. U. =Unique sequences; . H. = Highly repetitive sequences. U: occur once in genome; H: occur many times;. U: long base sequences; H: short sequences/5–300 bases;. Class name – VIH. Course name - ZOO-Biotech. (Rohit). DNA MICROARRAY. Introduction. As we know that for molecular characterisation of any gene/genome, nucleotide sequences are required.. Understanding the genome function by analysing the genes and the ways the genes expressed by the genome have a key importance.. The helical structure of . DNA. Formation of Nucleotides. Structure of polynucleotide polymer. Each base has its preferred . tautomeric. form. Purine. and . Pyrimidine. Base . tautomers. ; are frequent sources of errors during DNA synthesis.  .
