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. 1. Transcription: The DNA unwinds and unzips in the area of the gene. A promoter is needed in order to start. Enzymes match RNA nucleotides to the unzipped nitrogen bases of the gene, forming a single strand of mRNA. 2. The strand of mRNA detaches from the gene and goes out of the nucleus through one of the pores in the nuclear envelope. The DNA zips back together and winds back up. 3. The mRNA finds a ribosome where protein synthesis will happen.
