Study Notes
DNA Function and Genetic Engineering
- The primary function of DNA in living organisms is to store genetic information and pass it from one generation to the next.
Genetic Engineering Applications
- A potential application of genetic engineering is to introduce desirable traits into organisms, such as pest resistance or drought tolerance in crops.
Restriction Enzymes
- Restriction enzymes are used in genetic engineering to cut DNA molecules at specific recognition sites, allowing for the insertion of desired genes into a vector.
DNA Ligase
- DNA ligase is an enzyme used in genetic engineering to seal gaps in DNA strands, forming covalent bonds between adjacent nucleotides.
Plasmid Vectors
- Plasmids are used as vectors in genetic engineering to transport genes into host cells, allowing for the expression of desired traits.
Polymerase Chain Reaction (PCR)
- PCR is a laboratory technique used to amplify specific DNA sequences, enabling the analysis of small DNA samples and facilitating genetic engineering and forensic applications.
