Coding regions - sequences of DNA that serve as instructions for making proteins (1-2% of human DNA) Non-coding regions - Human DNA that contains STRS and are responsible for regulatory functions ( DNA transcription 98-99% ) What are STRs? - short tandem repeats; unique repetition of nucleotide patterns. Differentiate one person from another. What is a DNA profile? - a specific pattern of DNA attributes that is obtained in the lab and can be used to identify an individual; is the process of determining an individual's DNA characteristics (profile) from a sample of bodily tissue What does PCR stand for? - polymerase chain reaction What is the purpose of PCR? - to amplify a specific desired fragment of DNA (make more copies) What is inside the master mix (forensic biology I)? - 3 pairs of primers, loading dye, nucleotides (dNTPs), Taq polymerase, mix buffer, and water.
