Mirsky graduated from Harvard College in 1922, after which he studied for two years at the College of Physicians and Surgeons of Columbia University until 1924 when he moved to the University of Cambridge on a US National Research Council fellowship. He received his PhD from Cambridge in 1926, with a dissertation on the Haemoglobin molecule.

On May 25, 1926 Mirsky married Reba Paeff, who went on to become a renowned children's author; they had a daughter and a son.

In 1927 Mirsky was appointed Lab Assistant to Alfred E. Cohn at the then Rockefeller Institute for Medical Research, beginning his association with Rockefeller University. During a sabbatical year at the California Institute of Technology, Mirsky published a paper with Linus Pauling on the general theory of protein structure, suggesting that the structure of proteins are coiled in a specific configuration that accounts for the function in the body, and that the protein is denatured when that configuration is lost by breaking the hydrogen bonds that stabilize the structure.

Mirsky became an official Member of the Rockefeller Institute in 1948, and in 1950 was internationally congratulated for the "grand discovery" of DNA constancy, which proved the concept of DNA as the hereditary material.

Mirsky was made Professor in 1954 when the Institute became Rockefeller University. He was also elected to the United States National Academy of Sciences in the same year. Mirsky was highly involved in university affairs, and in 1959 he initiated a series of lectures for high school students, now named the Alfred E. Mirsky Holiday Lecture on Science in his honour.

In 1962 Mirsky chose a new lab assistant from a pool of candidates, in choosing a woman, Ellie Donoghue, he set a precedent by making her the first female lab assistant in the Institute's history, the very same position which he first held upon his initial association with Rockefeller Institute. Mirsky proceeded to entrust Ms. Donoghue with assistance in his research and the running of his laboratory, setting an early precedent for the advancement of women in the labs at Rockefeller University.

Following retirement from his laboratory in an official capacity in 1964, he served as librarian of the Rockefeller University from 1965 until 1972, all the while being allowed to maintain his laboratory at the university for his personal research, He continued to make groundbreaking contributions to the study of cell nuclei in rodents and bovines in direct parallels to the structure of cell nuclei in humans.

After his wife, Reba Paeff Mirsky, died in 1966 he donated her valuable jewelry collection, save for a few pieces distributed to family and close friends, to the university's collection. This collection of jewelry, acquired during their many trips around the world, is a part of the university's holdings to this day. He went on to marry fellow Rockefeller employee Sonia Wohl in 1967. Mirsky became professor emeritus in 1971, after forty-four years at the Rockefeller Institute and University.

Mirsky traveled widely and was quite knowledgeable in archaeology and art history; his priceless collection of art and historical objects was willed to the Rockefeller University upon his death in 1974 and remains in their permanent collection.
