China's plan to cut meat consumption by 50% cheered by climate campaigners. China now consumes 28% of the worldâs meat, including half of its pork. The Chinese government has outlined a plan to reduce its citizensâ meat consumption by 50%, in a move that climate campaigners hope will provide major heft in the effort to avoid runaway global warming.
Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the main transcription enzyme. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination. Termination depends on sequences in the RNA, which signal that the transcript is finished.
The mRNA molecule is elongated and, once the strand is completely synthesized, transcription is terminated. The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
