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.
mutations .
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.
(Apex Learning) It was developed by many scientists over many decades.
The structure of DNA is stable but it can undergo mutation once in a while to provide the raw materials for natural selection to act upon. lol from Kaplan huh?
The structure of DNA was determined by James Watson and Francis Crick back in 1953

The structure of DNA( in over all) similar to twisted ladder.

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.
Very little. The content and structure is almost identical. The only difference is found in a few base pairs here and there.
No. DNA is not a vestigial structure as it has not ceased to function
