Wikipedia has a good section on this:
DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it "nuclein".[117] In 1919 this discovery was followed by Phoebus Levene's identification of the base, sugar and phosphate nucleotide unit.[118] Levene suggested that DNA consisted of a string of nucleotide units linked together through the phosphate groups. However, Levene thought the chain was short and the bases repeated in a fixed order. In 1937 William Astbury produced the first X-ray diffraction patterns that showed that DNA had a regular structure.[119]
What else can I help you with?
Who first isolated DNA from white blood cells?
Adam Walley Ph. D Harvard University Advanced Sociology Professor
Why do scientist isolate DNA?
Scientists isolate DNA to study its structure, sequence, and function. By isolating DNA, scientists can analyze specific genes, create genetic maps, and understand how genes contribute to traits and diseases. Isolating DNA also allows for techniques like PCR and DNA sequencing to be performed.
When did DNA polymerase first discovered?
DNA polymerase was first discovered in 1956 by Arthur Kornberg and his team at Washington University in St. Louis. They isolated the enzyme from E. coli bacteria and demonstrated its role in DNA replication.
A scientist wants to instert a new gene into bacterium what is the first step in this process?

What was the first virus to be isolated?
The first virus to be isolated and identified was the tobacco mosaic virus in 1892 by Russian scientist Dmitri Ivanovsky.
When was DNA found?
DNA was discovered in 1869 by Friedrich Miescher, a Swiss biochemist, who first isolated it from cells. Its significance in heredity and genetic information was not fully understood until later in the 20th century.

Did an African American contribute to the discovery of DNA?
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.
