Which best describes step 3 in the diagram?
restriction enzymes cut the dna into fragments; the fragments join with the host dna to create recombinant dna.
recombinant dna is inserted into a biological vector; the vector houses the recombinant dna and is capable of creating copies of dna for itself and the recombinant dna.
cloning of the recombinant dna occurs; the dna is cloned in the biological vector to create more dna for use in the host.
recombinant dna is inserted into a mechanical vector; the mechanical vector allows the dna to be inserted into the dna clone for use in the host.

Recombinant DNA is inserted into a biological vector

The vector houses the recombinant DNA and is capable of creating copies of DNA for itself and the recombinant DNA

Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
