  • A gene consists of clusters of nucleotides, with coding regions
    Exon
  • concurrence of symptoms
    Syndrome
  • A molecule of single-stranded DNA that is complementary to a run of nucleotides in one or more of the restriction fragments
    Probe
  • these are enzymes present in all cells which help to stick the sliced dna molecules together
    DNA ligases
  • The DNA strand coils round protein molecules
    Histones
  • certain factors called mutagens increase the chance of mutations occurring
    Mutagens
  • A method for making many copies of a specific segment of DNA.
    Polymerase chain reaction(PCR)
  • Enzymes that are used to cut parts of DNA. They have very specific ‘sticky’ edges.
    Restriction Enzyme
  • Biotechnology
    is the use of organisms to perform specific manufacturing processes

    DNA analysis
  • Change in 1 few nucleotides in a DNA sequence
    Gene Mutations
  • A group of nucleosome
    Solenoid
  • two chains of polynucleotides

    Inherited
  • proteins they DNA tightly coils around to form chromosomes.
    Nuclesome
  • Change in the number or structure of chromosome
    Chromosome Mutations -
  • The DNA molecules form a complex with proteins
