No, DNA was first isolated by the Swiss physician. Also there were no African Americans involved in any subsequent work on DNA leading to the understanding of it structure.
You can tell if you perform an ancestry DNA test. Sometimes its not enough to go by appearance alone. But African American is just one category of 'African'. You can be of African ancestry and not be American. In the USA, it's no longer important to be of African ancestry since the Jim Crow era is in the past and no longer applies today.

James Watson and Francis crick together with Maurice Wilkins announced their discovery of DNA in 1953, winning the Nobel prize in medicine.
Yes. There are many African Americans with extremely light and fair skin. Many people of African lineage are so fair that they have lived in the white world and their friends and sometimes family have no idea they have African heritage. There have been some very interesting documentaries produced on the topic. Modern DNA testing has shown that most African Americans have European ancestors which was, in most cases, not by choice. Passing as white has always been a way for light skinned African Americans to gain opportunities that would otherwise be denied. There are stories of slaves who escaped slavery because they could pass as white. See related link.
We all originate from the DNA of the first African people, but through evolution, we have developed races.
The discovery of DNA as the genetic material was the unified theme.
She and Maurice Wilkins worked together and took some x-rays of DNA. The DNA crystallography allowed Watson and Crick to look at the picture to determine it was a double helix and not a triple helix as Linus Pauling had thought.
The discovery of the replication mechanism of DNA answered questions about evolution

Watson and crick and the discovery of the double helix
All scientific investigations are of benefit to us in some way. The most recent? How about the discovery of water on Mars? Or the mapping of DNA molecules?
the discovery of the structure of DNA, which occurred as the result of an x-ray image of a DNA molecule
It showed that DNA had a double helix shape
DNA has sugar, phosphate, and a nitrogenous base.
The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.
