1. Recombinant DNA & Mutations
DNA Technology
Gene/Point Mutations
Chromosome Mutations

2. Recombinant DNA
Researchers insert the DNA of one organism in DNA from another organism.
This technology can be used to do various things that could improve human life:
Mass production of a
useful protein
Repairing genetic
errors
Hybrid species of
food crops

4. Mutations Gene (Point) versus Chromosome Mutations
The time at which a mutation occurs determines the effect:
Ex. During Replication – all resulting cells will have the mutation
Ex. During Translation or Transcription – may have little or no effect because it only affect a single protein in one cell

5. Mutagens A factor in the environment that leads to a mutation
Ex. Radiation and Chemicals

6. Types of Mutation Deletion Addition Substitution
Deletions and Additions typically result in cell death
Substitution may have no effect (degenerative) or change a protein entirely

7. Mutation
