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.'

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
