The correct answer is: b. It is free to bind to another promoter and begin transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex.
RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.

Answer:
Recycled Ammonia
Explanation:
Ammonia can be extracted from livestock wastewater and used as a fertilizer. There are systems available that extract the ammonia and mix it with acids to create ammonium citrate or ammonium nitrate, both of which can be used as fertilizers. The extraction system removes ammonia from the waste, which significantly reduces the amount of ammonia that is released into the air. This has the added bonus of improving the air quality where animals are kept.
Answer:
both can react to form acidic compounds
