Although there are three forms of DNA that have been discovered (A form, B form and the Z form), the structure of DNA itself is the same in all organisms.

DNA may be packed differently or may contain additional chemical groups attached to the bases (like methylated DNA). However, the structure of DNA is similar in all organisms. This is the reason why it has been named the molecule of life.

What best describes why our understanding of DNA and inherited traits has changed over time?

As with any knowledge, it takes time to discover all the parts. The structure of DNA took time to learn. Then the fact that there were recurrence of 4 bases and these bases had matching bases on the second strand of DNA. We did not have the tools at first. As they came along, we learned more and more.

Who deciphered the structure of DNA?

The first picture and model of the DNA structures were made from Rosalind Elsie Franklin. Over the years William Watson and Francis Crick stole the idea from her and worked out the structure of DNA as if they invented it.
