Question:

Is Psychology a science or social science subject? What makes it unique and worth learning as it seems to be very common sensical in nature?

Ritam D.
Answer:

Psychology is generally taught under the purview of Social Sciences but the components and methodology of Cognitive, Neuroscience and Experimental relates more to basic sciences than that of social sciences. Psychology in simple terms is a beautiful amalgamation between philosophy, sciences and social sciences. The simple nature of this amalgamation taught under the strict observance of scientific principles is what makes Psychology unique. Additionally, there are varied school of thoughts including very famous Psychoanalytic school of Sigmund Freud which tries to cross the boundaries of classic scientific exploration to decipher human behaviour.

Question:

Why is Deoxyribonucleic acid present in a eukaryotic cell twisted in a double helix form?

Ritam D.
Answer:

In a eukaryotic cell, the genetic material that decides the fate of the organism and is composed of Deoxyribonucleic acid which is again composed of sugar, phosphate molecules and nitrogenous bases. The twisted double helix structure of DNA is due to hydrogen bonds with nitrogenous bases. The nature of nitrogenous bases is hydrophobic and hence they prefer to be away from the water present as it comprises the majority of the cell volume. In addition, the phosphate molecules and sugar are hydrophilic in nature and the twisted structure saves spaces between the two which makes this structure most stable.
