Smelling hair in a dream is a message of secrets. To be enjoying the aroma of hair may mean exciting and happy secrets that you will derive pleasure from. To be dreaming of foul-smelling hair implies secrets you would rather not hear and that you are not obligated to keep.
Ras Pathway. Ras is a membrane-associated guanine nucleotide-binding protein that is normally activated in response to the binding of extracellular signals, such as growth factors, RTKs (Receptor Tyrosine Kinases), TCR (T-Cell Receptors) and PMA (Phorbol-12 Myristate-13 Acetate).
The CRISPR/Cas system is a remarkably flexible tool for genome manipulation. One of the primary advantages of the technology is that the nuclease activity and the DNA-binding activity of Cas9 are discrete functions in the protein. The Cas9 nuclease activity (cut) is performed by 2 separate domains, RuvC and HNH.
