Explain through the Watson-Crick model, the secondary structure exhibited by the nucleic acids.​

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.

blah

explanation: bc blah

well, since there is no answer choices, i will give an answer on how it works : )

the two objects are placed together. energy will always be transferred from the hotter object to the cooler object until they are equal. hope this is close to one of the answer choices : )
