Answer:

A) it causes mutation leading to cancer .

Explanation:

Cancer is the disease that occurs when cells exhibit uncontrolled cell division leading to the formation of an undesired group of cells. Any chemical or physical factor that causes mutation in the genes of cell division control and leads to cancer is called a carcinogen. Tobacco smoke is a carcinogen as it has the ability to mutate the DNA of individual to cause cancer.

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:

  1. The first step is to isolate a DNA fragment, which contains the gene of interest. Remember that each gene makes a protein.
  2. The gene of interest, now isolated, is placed in a medium with a fragment of circular bacterial DNA, the plasmid and the restriction enzymes.
  3. 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.

What is the journey of a pice of cheese through your digestive system. Starting with the stomach and ending with absorption. Inc
allochka39001 [22]
Cheese is composed of fats and proteins. On reaching the stomach gastric juice is produced, which contains pepsin that acts on proteins to form dipeptides. In the duodenum, enzymes trypsin and chymotrypsin released from the pancrease acts on dipeptides to produce peptides. Bile juice from the bile acts on fats to form small fats droplets a process called emulsification. In the small intestines enzyme peptidase acts on peptides to form amino acids, while enzyme lipase acts on fat droplets to produce fatty acids and glycerol. Amino acids, fatty acids and glycerol are then absorbed into the blood stream.
