In 1959, he demonstrated that mRNA is significant in protein synthesis. By contributing to the central dogma, he showed that just like DNA, mRNA can be used to determine the genetic code. His experiment involved a cell whose DNA was denatured but injected with mRNA and showed that protein synthesis proceeded.
Using the doppler effect helps astronomers calculate how fast the stars and other objects move toward or away from earth.
One of the reasons the plasma membrane can have<span> selective permeability</span><span> it's because it's composed by a bi-layer of phospholipids.
The interaction between them and other molecules will influence how these molecules will cross the membrane. If the molecule it's </span>hydrophobic it can easily cross, if it's polar molecules and ions( hydrophilic), they cannot cross easily.
When heat is added to a substance, the particles move faster. W
