Earth’s tilt on its axis and revolving around the sun.
The organelles and substances inside the organelles are smaller.
Answer:
The analysis of protein structure by frozen electron microscopy can be divided into three processes:
1. Sample preparation: the biomacromolecule sample is frozen rapidly in liquid nitrogen, and the water in the macromolecule exists in the form of glass.
2. Data collection: irradiate the sample and the ice near the sample with low energy electron beam, and record the scattered signal with detector.
3. Three dimensional reconstruction to build protein model: three-dimensional structure of protein is built by two-dimensional projection from different angles.
