#Unit 13. Methods in Biology
There are two proteins A and B to be visualized under fluorescence microscopy. Both of them are excited with same wavelength of light but A emits longer wavelength. Hence we can conclude that
1. A is denser molecule than B
2. B is denser molecule than A
3. A is lighter molecule than B
4. B is lighter molecule than A
