5 Written questions

5 Matching questions

  1. how does gene manipulation happen?
  2. heredity
  3. proteins
  4. DNA molecules
  5. protein synthesis
  1. a to build
  2. b is the passing on of genetic information from one generation to the next through reproduction
  3. c 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
  4. d contain the genetic code for all organisms
  5. e -carry out most of the cells
    -can be enzymes, hormones, antibodies, or make up parts of cell organelles
    -the DNA code of gene is read in the nucleus and a messenger molecule is created (messenger RNA)
    -the message travels to a ribosome in the cytoplasm

5 Multiple choice questions

  1. two identical copies of the cell's genetic information
  2. an alteration in a sequence of DNA
    -change the normal message carried by the gene, causing a defect
    - they are random
    -affect the synthesis of proteins, which causes malfunctions in the cell. EX.) sickle cell anemia is caused by a substitution in the cell
    -can cause cell death
  3. -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
  4. share all genes from one parent (identical/clones)
  5. 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

5 True/False questions

  1. if a cell survives a mutation...a sugar, phosphate, and a nitrogenous base


  2. new DNA molecules are made by...attaching matching base pairs of DNA to each template


  3. the order of amino acids is determined by the DNA codeselective breeding and gene manipulation


  4. genetic engineeringa new technology used to alter the genetic instructions of organisms


  5. single stranded DNA becomes...a template for a new DNA molecule to be made
