Patterns of histone modifications are implicated as having a role in directing the level of chromatin compaction, as well as playing roles in multiple functional pathways directing the readout of distinct regions of the genome.hromosomes in eukaryotic cell nuclei are not uniformly organized, but rather contain distinct chromatin elements, with each state having a defined biochemical structure and biological function.
FM - Frequency Modulation. In Telecommunication, Frequency Modulation is a technique of transmitting information using a carrier wave. The frequency of the carrier wave is varied in accordance with the amplitude and polarity of the input signal.
When you listen to a radio station and the announcer says, You are listening to 91.5 FM WRKX The Rock!, what the announcer means is that you are listening to a radio station broadcasting an FM radio signal at a frequency of 91.5 megahertz, with FCC-assigned call letters of WRKX.his band of the radio spectrum is used for no other purpose but FM radio broadcasts. In the same way, AM radio is confined to a band from 535 kilohertz to 1,700 kilohertz (kilo meaning thousands, so 535,000 to 1,700,000 cycles per second).
