Blood-Brain Barrier prevent material from moving in or out of the brain's capillaries.
What is blood-brain barrier?
- All of the body's tissues and organs depend on blood arteries to carry oxygen and nutrients to them.
- The blood-brain barrier, a special property of the blood arteries that vascularize the central nervous system (CNS), enables these vessels to tightly control the transit of ions, chemicals, and cells between the blood and the brain.
- Correct neuronal function is enabled by the careful regulation of CNS homeostasis, which also safeguards neural tissue from toxins and infections.
- Alterations to these barrier qualities play a significant role in the pathophysiology and development of various neurological illnesses.

That's weird, they all are...
Answer:
3000
Explanation:
- Human haploid genome >>> 3 x 10⁹ base pairs >>> 3,000,000,000 base pairs
- Human haploid genome >>> 10⁶ copies >>> 1,000,000 Alu Transposable Elements
- Space between each Alu Transposable Element (TE) >>>
3,000,000,000 base pairs / 1,000,000 Alu elements = 3,000 base pairs
Alu elements are highly repetitive DNA sequences that account for approximately 20% of the human genome. These sequences (Alu) are considered to be non-autonomous Transposable Elements (TEs) capable of transposing within the genome via an RNA intermediary.
