Scientists use transgenic organisms to produce large amounts of human insulin in labs. Which action should be the first step in making a transgenic organism that can produce human insulin? A. Find an organism with a gene similar to the one for human insulin.

B. Insert a gene similar to the one for human insulin into a bacterial cell.

C. Insert the gene for human insulin into humans who need insulin.

D. Find the gene for insulin in a human's DNA.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
