Which best describes the process of making recombinant dna? the isolated dna is inserted into a mechanical vector for cloning. the dna fragments are connected to a carrier to be inserted into a host. the sticky ends of fragmented dna are joined with vector dna. the isolated genes are joined by using restriction enzymes.

Answer;

The sticky ends of fragmented DNA are joined with vector DNA.

Explanation;

-Recombinant DNA is a type of DNA that is made artificially through the combination of two or more gene sequences. The recombinant DNA is engineered for the purposes of many applications in genetic engineering.

-The process of generating a recombinant DNA is based on the ability to cut and re-join DNA molecules. The molecules of DNA are joined at points identified by restriction sites, such that the sticky ends of fragmented DNA are joined with a vector DNA.

Ans.

Recombinant DNA (rDNA) represents DNA molecule, formed in laboratory conditions (in vitro) by recombining genetic material from different sources, using genetic engineering with new properties. The resulting recombinant molecule is then inserted to the host cell to get desired product.

Vector DNA helps in transport of DNA of interest to the host cell, where it replicates or expressed. The process that makes recombinant DNA involves joining of DNA of interest with vector DNA with the help of ligase enzymes at the sticky ends of DNA, produced by restriction enzymes.

Thus, the correct answer is option). 'the sticky ends of fragmented DNA are joined with vector DNA.'
