Pairing of a specific purine to a specific pyrimidine is due to the structure and properties of each ring and the three-dimensional fit between complements. Purine and pyrimidine are organic, aromatic ring compounds that act as the building blocks of nucleic acid. In DNA, purines occur as adenine and guanine, while pyrimidines occur as thymine and cytosine. In DNA base pairing, adenine pairs with thymine, and guanine pairs with cytosine

Answer:
Deposition
Explanation:
Landslides occur under the effect of gravity. When a mass of rock or earth slides down from a mountain or from a cliff then this phenomenon is termed as Landslide.
Landslides are considered to be a rapid method of erosion. Wind, waves, running water, glaciers and gravity are the five agents of erosion out of which the gravity influences the process of Landslides.
Landslides occur suddenly and are dangerous example of the movement of earth materials under the influence of gravity. When weathered material falls away from a cliff, it slides down under the effect of gravity and finally after reaching the hill, the material gets deposited there. This is called Deposition by landslides.
