Venous blood from the ankle travels and goes through tibial vein, popliteal vein, femoral vein, external iliac vein, common iliac vein, inferior vena cava to the heart (right side). From the heart to the right side of the brain, blood goes through the aorta and the brachiocephalic artery. The brachiocephalic artery the then divides into the right common carotid artery and the right subclavian artery and both supply the right side of the brain.

Don’t mind me I just need to answer a question
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.
