5 Matching questions

  1. mutations are due to...
  2. single stranded DNA becomes...
  3. types of genetic engineering
  4. new DNA molecules are made by...
  5. how does gene manipulation happen?
  1. a special enzymes (restriction enzymes) cut DNA at specific sequences, which allows the DNA to be spliced or inserted, into a new organism
    -organisms will make proteins that express the new trait, and pass it on to their offspring
  2. b insertion, detection, or substitution
  3. c attaching matching base pairs of DNA to each template
  4. d selective breeding and gene manipulation
  5. e a template for a new DNA molecule to be made

5 Multiple choice questions

  1. is the passing on of genetic information from one generation to the next through reproduction
  2. organisms have been genetically engineered to possess certain traits
    -flowers resistant to bugs
    -bacteria that feed on chemicals in oil spills
    -bacteria that produce HGH and insulin
    -plants resistant to herbicides
  3. a new technology used to alter the genetic instructions of organisms
  4. replicate or copy, its coded instructions
  5. weak hydrogen bonds with may be broken to split into DNA into two single strands

5 True/False questions

  1. gene expression-every body cell contains a complete set of identical genetic instructions
    -cells have selective activation of only the genes necessary for that cell
    - the environment can also affect the expression of genes


  2. each subunit contains...-the traits inherited by an individual can be determined from one pare of genes or by several pairs of genes
    -some gene pairs can influence more than just one trait
    -some traits are observable, while others are not (examples: hair or eye color, ability to produce insulin, or types of receptors on cell membranes)


  3. DNAis an organic molecule made of many small subunits called nucleotides (monomers)
    -double helix molecule


  4. selective breedingproducing domestic animals and new variations of plants with desirable traits
    -animals are breed to contain less fat
    -fruits to be larger, sweeter, and longer lasting


  5. 4 nitrogenous basesA,T,G and C (Adrenine, Thymine, Guanine and Cytostine)
    A and T, G and C
    -sequence of bases in a DNA molecule forms a coded message
