HOW DID VIRUS MAKE NEW VIRUS PARTICLES?
|
Viruses held information on substances that were required to make new virus particles, which by infecting a host cell, trick the host cell’s metabolic machinery into synthesizing the substance by using their enzymes

X-RAY DIFFRACTION IMAGES
|
IMAGES THAT FORM AFTER A BEAM OF X-RAYS IS DIRECTED AT A MOLECULE, WHICH SCATTERS THE X-RAYS IN A PATTERN THAT CAN BE CAPTURED ON FILM.
PATTERN ONLY CONSISTS OF DOTS AND STREAKS RESEARCHERS USE IT TO CALCULATE THE POSITIONS OF THE MOLECULE'S ATOMS. ROSALIND FRANKLIN MADE FAMOUS X-RAY DIFFRACTION IMAGES OF DNA. |
