It is B, it could also be D, but it is most likely B. Hope this helps.
Explanation:
Watson & Crick discovered that DNA is composed of two (2) strands of DNA running antiparallel to each other. One strand is oriented in the 5’ -> 3’ direction while the other is oriented in the 3’ -> 5’ direction. The nitrogenous bases of the strands are found in between the two-strand backbones and they form hydrogen bonding with each other. Specifically, pyrimidines (Cytosine and Thymine) pair with purine (Adenine and Guanine).
The space between the strands is even throughout like a ladder with rungs of equal lengths. However during the twisting on the DNA helix, there are major grooves and minor grooves that form along the helix because of the nature of how the nitrogenous bases are attached to their respective strand. They do not project from their strands at 90 degrees.

I think the correct answer from the choices listed above is option A. The most common metrical pattern in English poetry most likely is the iambic pentameter. It is a line with five metrical feet. It is the meter used by Shakespeare in most of his works.
Schizophrenia is a mental disorder defined as chronic and severely debilitating as the patients usually are "lost in touch with reality."
Schizophrenia has both positive symptoms (added) and negative symptoms (lack of). Positive symptoms include hallucinations (<em>adding </em>unreal imagery) and uncontrollable thoughts. Negative symptoms include apathy <em />(<em>lack of </em>concern or enthusiasm), alogia (<em>lack of </em>speech), and blunted affect (<em>lack of </em>facial expression). Both positive and negative symptoms affect the intellectual functioning of an individual with schizophrenia.
