What are the primary, secondary, and tertiary structures of DNA and RNA defined as?



Expert Answer

Step 1

DNA and RNA are the genetic material present in living organisms. Generally, the DNA appears as the double-stranded helical structure whereas the RNA exists as single strands. 

Step 2

The primary, secondary, and tertiary structures of DNA.

 Primary structure: The DNA contains four nitrogenous bases, and possess similar primary structure with that of protein. The bases are adenine, guanine, thymine and cytosine. This structure possesses a phosphate backbone where the nitrogenous bases are attached.

Secondary structure: This structure can be defined as the set of instruction between the nitrogenous bases where the parts of the DNA strand is attached to each other. The double strand of DNA is ...
