  5. single stranded DNA becomes...
  1. a are sequences of DNA that contain a code of instructions for a specific trait
    -a human cell contains many thousands of different genes, located on chromosomes, in its nucleus
  2. b attaching matching base pairs of DNA to each template
  3. c a template for a new DNA molecule to be made
  4. d move specific amino acids to the ribosome, which are strung together to make a protein (transfer RNA)
  5. e a new technology used to alter the genetic instructions of organisms

5 Multiple Choice Questions

  1. two identical copies of the cell's genetic information
  2. A,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
  3. 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
  4. allows for offspring with high variation
  5. the changed instructions will be passed on to all cells coming from in

5 True/False Questions

  1. gel electrophoresistechnique used to separate DNA


  2. DNA moleculescontain the genetic code for all organisms


  3. heredityis the passing on of genetic information from one generation to the next through reproduction


  4. translationgoing from mRNA to protein


  5. proteins-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
