Francis Crick
James Watson helped to discover the shape of a DNA molecule. A double helix
With the help of Rosalind Franklin, Watson and Crick built a tin model of a DNA molecule that helped scientists better understand the structure of DNA.

Sorry I dont know but by any chance are you in Tanglin Trust School Year 10?
Observing the patterns of DNA, like noticing the amount of adenine always equalled the amount of thymine (the same with guanine and cytocine), and using x-rays to study the structure of molecules, helped scientists such as Erwin Chargaff to discover the structure of DNA.

microscopes have helped scientists to dicover cells and discover their functions. they have helped scientists examine the anatomy of tiny organisms and insects, and inspect organs of all species more closely.

The Telescope
The Hubble telescope helped scientists to do this.

the scientist was Dr. alfred wegener.
it helped scientists discover small organisms and make the periodic table
James Watson and Francis Crick solved the structure of DNA. Other scientists, like Rosalind Franklin and Maurice Wilkins helped.
She was close to solve the 3D structure of the DNA molecule, she had even got the X ray diffraction pattern that was helped solve the structure by Watson and Crick.
