In a garden plot, you count 50 tall plants and 50 short plants. All the plants are offspring of the same two parent plants. What is the ratio of tall to short plants?

ANSWER:

Nucleic acids display a wide variety of secondary structures. For example, the Watson-Crick model. It proposes that the DNA exists as a double helix structure, wherein the two strands of the polynucleotides run in the opposite direction. Its backbone is formed by the sugar-phosphate-sugar chain where in the nitrogen bases are proposed almost perpendicular to this backbone, facing inwards. A and G of one strand base pairs with T and C respectively on the other strand. Between A and T there are two hydrogen bonds and between G and C, there are three hydrogen bonds wherein each strand appears as a helical staircase. One complete turn of the helical strand has ten base pairs.
