1. Watson and Crick: they confirmed the three-dimensional structure of deoxyribonucleic acid (DNA).

2. Miescher: he was the first to discover deoxyribonucleic acid (DNA) and named it “nuclein.”

3. Franklin: he took the first photo of deoxyribonucleic acid (DNA) which helped scientists understand its structure.

4. Wilkins: he studied deoxyribonucleic acid (DNA) by using special X-rays.

Deoxyribonucleic acid (DNA) can be defined as the central information storage system (cell's hereditary materials) of a living organism, which contains the instructions that are responsible for its growth, development, and reproduction. Also, deoxyribonucleotides is the basic unit of a deoxyribonucleic acid (DNA).

In this exercise, you're required to match the name of scientists to their discoveries with respect to cells.

1. Watson and Crick: they confirmed the three-dimensional structure of deoxyribonucleic acid (DNA).

  • James D. Watson and Francis H. C. Crick were students of Cambridge university who discovered the double-helix structure of deoxyribonucleic acid (DNA).

2. Miescher: he was the first to discover deoxyribonucleic acid (DNA) and named it “nuclein.”

  • Friedrich Miescher was the first to discover deoxyribonucleic acid (DNA) as a distinct molecule in 1869, by isolating nucleic acid.

3. Franklin: he took the first photo of deoxyribonucleic acid (DNA) which helped scientists understand its structure.

  • Rosalind Elsie Franklin took the first photo of deoxyribonucleic acid (DNA) in May 1952 and named it "Photo 51."

4. Wilkins: he studied deoxyribonucleic acid (DNA) by using special X-rays.

  • Maurice Hugh Frederick Wilkins studied deoxyribonucleic acid (DNA) by using special X-rays, microscopes and spectrophotometers.
