Gel-shift experiments
WebJun 20, 1997 · We used gel-shift experiments (Fig. 3 A) to test interactions of ARF1 with the P3 (4×) DNA sequence. Two complexes were observed that may represent different numbers of ARF1 proteins bound to P3 (4×). ARF1 also bound to the natural D0 AuxRE sequence, although with lower affinity. WebJul 21, 2024 · Color Mixing and the Physics of Color. The following "colorful" science experiments relate to how visible colors shift due to the mixing or separation of light. Colored Shadows: mix red, green and blue light to investigate additive color mixing and how our eyes perceive colors. ( Student project version)
