Accuracy 
a measure of how close a result matches a correct or standard value 
 
 
 
Precision 
a measure of variability. For example, three darts placed close together on a dartboard indicate high precision, but if this cluster of darts is far from the bullseye it would also indicate low accuracy

What is the difference between the coding and non-coding region? 
Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions ...
