Question

module 2 exam 25 - 26 biology a / module 2: principles of inheritance 10. what role does recombinant dna play in genetic engineering? it is responsible for altering an organisms characteristics. it causes the endonuclease to act on dna and rna. it ensures that host dna is the site of cleavage. it becomes the point of attachment for dna and rna in the nucleus.

Explanation:

Recombinant DNA in genetic engineering is used to combine DNA from different sources. This allows for the alteration of an organism's genetic - makeup, which in turn can change its characteristics. Endonucleases act on DNA to cut it for recombinant DNA formation, not the other way around. Recombinant DNA is not related to ensuring host DNA cleavage site or being a point of attachment for DNA and RNA in the nucleus.

Answer:

It is responsible for altering an organism's characteristics.
