Answer:
6.4 million
Explanation:
The human genome contains 3.2 billion bases (nucleotides).
Each reaction can sequence a read length of 500 nucleotides. We are excluding overlaps, and redundant sequences (which in reality would always happen when performing sequencing). Therefore, the minimum number of sequencing reactions is the total number of nucleotides in the genome divided by the length of read 3.2 billion ÷ 500 = <u>6.4 million</u>
Quite simple really.... The CNS actually doesn't receive as much nutrients or key components from the blood... The blood actually dumps it into the Cerebrospinal fluid. The Cerebrospinal fluid therefore is directly in contact with the brain and if you want to find an infection you take from a source as close to thing as you can.
