Recombinant Dna Molecules

Science / Biology / Recombinant Dna Molecules: New combinations of DNA fragments formed by cutting DNA segments from two sources with restriction enzyme and then joining the fragments together with DNA ligase. Interspecies transfer of genes usuall MORE

Polar Molecule

Science / Chemistry / Polar Molecule: An asymmetric molecule containing polar bonds. H2O, NH3, and hcl are examples of polar molecules. Non-examples are CO2, ccl4, and bcl3 which contain polar bonds but are nonpolar because they have symm MORE

Nonpolar Molecule

Science / Chemistry / Nonpolar Molecule: A molecule in which the center of positive charge and the center of negative charge coincide. Examples are ccl4 and CO2; counterexamples are chcl3 and H2O. MORE

Macromolecules

Science / Biology / Macromolecules: Large molecules made up of many small organic molecules that are often referred to as monomers; e.g., carbohydrates, lipids, proteins, and nucleic acids. Macromolecules are polymers of monomers. MORE
