Electromagnetic waves are waves propagated by simultaneous periodic variations of electric and magnetic field intensity that include radio waves, infrared, visible light, ultraviolet, X-rays and gamma rays.
Damped oscillation means that there is some force that causes the oscillation to become smaller and smaller over time. For example, the pendulum exhibits an oscillation motion. Over time, the swinging of pendulum would come to a stop, unless a force is acted on it.
Forced oscillation means that an outside force causes an object to oscillate at a certain frequency. For instance, if you decide to swing the pendulum so that it won't stop from swinging, the action is called forced oscillation.
On the other hand, resonance oscillation refers to the increase in an amplitude of oscillation of an electric or mechanical system exposed to a periodic force whose frequency is equal or very close to the natural undamped frequency of the system.
Among the three types of oscillation, resonance is most likely to produce an electromagnetic wave.

The scientist collaborates with others to plan and carry out an experiment and then writes a paper that has a clear conclusion. He submits it to a professional journal for peer review, after which the results are presented publicly.
Answer:
The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.
