Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
The correct answer is that a bacteriophage lambda chromosome containing the human collagen gene, because Recombinant DNA is the name given to DNA molecules that have part of DNA derived from two or more sources, usually these sources are different species. Recombinant DNA technology is also known as molecular cloning or even gene cloning.
B. A bacteriophage lambda chromosome containing the human collagen gene
<h3>How is recombinant DNA produced?</h3>
Obtaining recombinant DNA is based on the molecular cloning technique. The process can be summarized as follows:
- The first step is to isolate a DNA fragment, which contains the gene of interest. Remember that each gene makes a protein.
- The gene of interest, now isolated, is placed in a medium with a fragment of circular bacterial DNA, the plasmid and the restriction enzymes.
- The bacterial plasmid has the ability to insert a fragment of DNA external to its own genome.
<h3>What is DNA and what is it for?</h3>
DNA is the structure responsible for the transmission of all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. Thus, the main function of DNA is to transport information contained in its sequences, called genes.

Answer:Copper is a mineral commonly used in electronics. Copper ore deposits were created by volcanic activity. Heat and pressure creates copper ore and deposited it in sedimentary rock layers. Copper is considered a resource.
