Answer: Yes, because Congress may adopt laws regulating navigable waters.
Explanation:
It should be noted that municipalities using copper-based paint on their intake pipes can successfully be prosecuted for violating the federal law because Congress may adopt laws regulating navigable waters.
Under the Supremacy Clause, when the action of either the state government or the local government conflicts with the federal laws which are deemed valid, then such cities can be prosecuted.
The Epcot ball is a 165-ft diameter geodesic sphere that is elevated above the ground to stand 180 feet tall. Each face of the polyhedron is divided into three isosceles triangles to form each point. In theory, there are 11,520 total isosceles triangles forming 3840 points. Some of those triangles are partially or fully nonexistent due to supports and doors; there are actually only 11,324 silvered facets, with 954 partial or full flat triangular panels.
importance of a probe
in hybridization process, molecular biologist label a short fragment of DNA or RNA, usually 10-1000 bases long tagged with a radioactive or fluorescent molecules. this fragment is usually referred to as hybridization probe.probe important both in southern and northern blotting processed because it is used to identify a certain sequence of DNA or RNA in a pool several sequences that have been obtained using nuclease.
process of labeling DNA sequence with a probe
after the DNA strand has been cut into several fragments using enzyme DNA nuclease, the fragments are separated using gel electrophoresis and then denatured using hcl to obtain strands. the single strand are then transferred to nylon membrane that has positive charge. the next step is where probes come in. to detect the DNA sequence of interest the nylon membrane is treated with solution containing tagged probes. since the probes have complementary sequence to the target sequence, it bind to that DNA sequence and detected later using X-ray film.
