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.
Transcription is the process by which the genetic information stored in DNA is used to produce a complementary RNA strand. In more detail, the DNA base sequence is first copied into an RNA molecule, called premessenger RNA, by messenger RNA (mRNA) polymerase.
