  • Inheritance of DNA
    Mendel- 1866
  • Recessive allele
    The allele that is not expresses when an individual has two different alleles.
  • .Heterocygotes
    Individuals with a dominant and a recessive allele
  • Genotype (genetic info)
    Sets of genes of a individual.
  • Alleles
    Different variations of a gene
  • Dominant allele.
    the allele that shows on the phenotype when the individual has 2 different alleles. Ex: purple F
  • Genes are located into chromosomes.
    Morgan- 1910
  • Polymerase chain reaction. (PCR)
    Technice to make many copies of a specific DNA region in vitro.
  • First image of DNA
    1952- Franklin
  • Amino- acids
    molecules that join together to form proteins.
  • Locus/Loci
    Position of a gene
  • Genetic engeneeiring
    Process that uses different laboratory technices to change the DNA.
  • DNA replication
    formation of an identical copies of the molecule of DNA
  • Dogma of molecular biology.
    Circk 1958
  • Cloning
    To produce two identical copies of DNA, cells or organisms
  • Genes
    Fragments of DNA with information for a trait
  • The double helix
    1953- Watson and Circk-
  • The genetic code
    Deciphered by Severo Ochoa
  • Homocygote.
    Both alleles are the same.
  • Phenotype
    External manifestation of genes.
  • Chromosomes are made up of DNA
    Avery McLeod- 1944
