Protein kinases are enzymes that transfer the terminal phosphate from ATP to an amino acid residue on the target protein. Many are located on the plasma membrane as integral membrane proteins or peripheral membrane proteins. What purpose may be served by their plasma membrane localization - -They can more readily encounter and phosphorylate other membrane proteins -Which of the following statements is a logical consequence of the second law of thermodynamics - -Every chemical reaction must ...

Muscle cells differ from nerve cells mainly because: - -they express different genes -Cell differentiation always involves: - -the production of tissue-specific proteins -Apoptosis does not involve? - -lysis of the cell -Absence of bicoid mRNA from Drosophila egg leads to the absence of anterior larval body parts and mirror-image duplication of posterior parts. This is evidence that the product of the bicoid gene - -normally leads to the formation of head structures -Proto-oncogenes ...
