A DNA molecule produced by combining DNA from different sources is known as
Digiron [165]

Answer:

A DNA molecule produced by combining DNA from different sources is known as recombinant DNA.​

Explanation:

Recombinant DNA (rDNA) can be obtained by coupling DNA fragments from different sources, a process that is performed at the restriction site level and uses enzymes.  

Once rDNA has been designed —cutting out fragments of DNA that are then reassembled— it must be brought to a specific location in the cells, to be copied and expressed, using means of transport called vectors.

<u>DNA recombination</u> is performed in biotechnology laboratories specialized in the manipulation of genetic material.

The other options are not correct because:

  • <u><em>Mutant or mutated DNA</em></u><em> is a DNA molecule with an alteration of its nitrogenous base sequence </em>
  • <u><em>Hybrid DNA</em></u><em> is a variant of recombiant DNA, in which only two DNA molecules from different sources are used. </em>
  • <u><em>Polyploid</em></u><em> refers to cells containing the genome of different species.</em>
