Summary of Recombinant DNA technology | DNA Vectors | Cloning Vector And Expression Vector
The video discusses recombinant DNA technology, focusing on DNA vectors, cloning vectors, and expression vectors. Vectors are essential for delivering target genes into host DNA for molecular cloning purposes. Key points covered include the types of vectors used, the necessity of vectors in molecular cloning, and the properties vectors should have, such as origin of replication, multiple cloning site, and selectable marker. The methodology presented involves using vectors to carry target DNA, using bacterial transformation for plasmid insertion, and utilizing different types of vectors for cloning large DNA segments. Cloning vectors are used for multiple cloning purposes, while expression vectors are used for gene expression inside host cells. Examples of vectors discussed include plasmids, cosmids, phage vectors, bacterial artificial chromosomes, and yeast artificial chromosomes. The video emphasizes the importance of selecting the appropriate vector based on the gene to be cloned and the size of the DNA segment.
### Methodology
- Utilize vectors as a delivery system for target genes in molecular cloning.
- Use bacterial transformation to insert plasmids into host cells.
- Select appropriate vectors based on the size of the DNA segment to be cloned.
- Differentiate between cloning vectors and expression vectors based on their specific functions.
- Incorporate specific elements in expression vectors such as promoters, transcription start and stop sites, and tag sequences for protein identification.
- Choose vectors like plasmids, cosmids, phage vectors, bacterial artificial chromosomes, and yeast artificial chromosomes for cloning based on their carrying capacity and compatibility with the DNA segment to be cloned.
