B. Two strands of DNA linked together

Explanation:

DNA (Deoxyribonucleic Acid) is a molecule present in the nucleus of the cells of all living beings and which carries all the genetic information of an organism.

It consists of a double spiral-shaped ribbon (double helix), composed of nucleotides. That is, its structure is characterized as two strands of DNA linked together.

The two strands that make up the DNA wrap around each other and join through hydrogen bonds, which are formed between the 4 nitrogenous bases of the nucleotides: Adenine, Thymine, Cytosine and Guanine.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
