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.
If the medical assistant noted irregularities in the heart rate when palpating the radial pulse, they would opt to take a patients apical pulse for a full minute to make sure they are accurately counting the number of heartbeats per minute.
Fe2O3 + 6HCl -> 2FeCl3 + 3 H2O
If you count the number of each elements on both sides, they are equal. If you need me to explain this better, let me know and I would be glad to help
RNA is single-stranded while DNA is double-stranded.
RNA contains uracil while DNA contains thymine.
RNA has the sugar ribose while DNA has the sugar deoxyribose.
