Yes A is the correct answer
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.

Refined carbohydrates are digested faster, leading to a fast rise in blood glucose levels.
Refined carbohydrates have a higher glycemic index than processed whole grains. That's because of their simple chemical structure, leading to powerful spikes in blood
sugar and insulin secretion. This immediate impact can lead to an increased risk for type 2 diabetes, overweight and heart disease.
lemon juice is 100 times as acidic as tomato juice. remember, each step in the pH scale represents a change in concentration by a factor of 10. since tomato juice has a pH of 4.0, and lemon juice has a pH of 2.0, the concentration would change by 10 times 10.
