Billy Bell What role does stopping codons play in a protein synthesis assay? The stop codon does not code for an amino acid, so protein synthesis ends when no new amino acid is added to the polypeptide chain. What role do stopping codons play in protein synthesis? These codons mark the end of the polypeptide chain during … Read more
How do you test for aluminum ions? How do you test for ammonium ions? Ammonium ions can be determined in a solution by adding a dilute sodium hydroxide solution and heating gently. If ammonium ions are present, it will be converted into ammonia gas. Ammonia has a characteristic suffocating odor. It also converts wet red … Read more
What determines how the geologic time scale is divided? On the geologic time scale, time is generally divided on the basis of the Earth’s biosynthesis, where the Cenozoic Era (i.e. Antiquity, Mesozoic, Cenozoic) represents the period of Earth’s history with advanced life forms, and the Precambrian (or Proterozoic and Hadean Eras) represent How is the … Read more
What forces act on a satellite in orbit? A satellite can be launched into Earth orbit by accelerating it to a high transverse velocity. When a satellite is in a circular orbit, gravity is the only force acting on it, which means the centripetal force and gravity must be equal: Fc = Fg. What is … Read more
What is the definition of aggregates in science? Aggregate is material left over by a moving glacier. This material is usually soil and rock. Just as rivers carry along all kinds of debris and silt that eventually accumulate to form deltas, glaciers carry all kinds of dirt and rock that accumulate to form moraine. What … Read more
