Recombinant DNA Technology Explained For Beginners

Recombinant DNA Technology

This section provides an introduction to recombinant DNA technology and its techniques.

Introduction to Recombinant DNA Technology

  • Recombinant DNA technology involves manipulating and isolating specific segments of DNA for cloning purposes.
  • A vector, often a plasmid in bacteria, is used to create a recombinant vector.
  • The gene of interest is combined with the plasmid from the bacteria.
  • The plasmid is a circular piece of DNA in the bacteria, consisting of complementary DNA strands.
  • Restriction enzymes are used to cut the circular DNA at specific points, creating sticky ends that are complementary to the gene of interest.
  • The gene of interest binds to the sticky ends of the plasmid.
  • Ligase enzyme can then be used to join the gene of interest with the plasmid.

This section continues discussing recombinant DNA technology and its techniques.

Cloning Process

  • Once the gene of interest has bound to the sticky ends of the plasmid, ligase enzyme helps join them together.
  • The resulting recombinant vector can be inserted into a cell for cloning purposes.

Conclusion

Recombinant DNA technology allows scientists to manipulate and isolate specific segments of DNA for various applications. By combining genes of interest with vectors such as plasmids, researchers can create recombinant vectors that can be cloned in cells.

Video description

Recombinant DNA technology is a series of techniques used to manipulate and isolate DNA segments of interest. In order to insert this isolate DNA into a cell for cloning, some type of vector is commonly used. To create such a recombinant vector a bacteria containing a plasmid and a cell containing the DNA of interest is used. The plasmid from the bacteria is combined with the gene of interest that has been isolated. This plasmid is a separate piece of circular DNA located in the bacteria and when we look closer at it we can see that it consists of complementary DNA strands just like normal DNA. By using restriction enzymes to cut this circular DNA at two specific points, one can create two sticky ends that are complementary to the DNA of interest, allowing for easier binding of the gene of interest. Then once the DNA strand of the gene of interest has bound to the two sticky ends of the plasmid, DNA ligase can be used to ensure proper binding. What we are left with is a recombinant DNA plasmid which can be inserted back into a bacterial cell for cloning or into a mammalian cell for transfection.
