The Long Count calendar is a system that counts 5 cycles of time. This is very similar to the Gregorian calendar system that counts days, months, years, centuries and millennia. The Maya system also does this, but the difference is in the name and magnitude of the various cycles.
Transcription produces a single-stranded RNA molecule known as messenger RNA, whose nucleotide sequence is complementary to the DNA from which it was transcribed. The mRNA acts as an intermediate between the DNA gene and its final protein product. The gene's DNA is used as a template to generate a complementary mRNA.
There are three stages that make up DNA transcription. First, DNA is transcribed by an enzyme called RNA polymerase. Then, transcription factors elongate the DNA strand and allow RNA polymerase to transcribe only a strand of DNA into a RNA polymer called messenger RNA. Finally, RNA polymerase continues along the DNA until it reaches what is called a terminator sequence.
