coding region - comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. non-coding gene - makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription short tandem repeats (STRs) - unique repeating patterns of the same nucleotide sequence. They can be used to differentiate one person from another. DNA Profile - specific pattern of DNA attributes that is obtained in the lab and can be used to identify an individual. DNA profiling is the process of determining an individual's DNA characteristics (profile) from a sample of bodily tissue polymerase chain reaction (PCR) - Purpose is to amplify DNA. In forensics, this can be used to obtain more DNA from a sample that would otherwise be too small to analyze What's inside master mix? - 3 pairs of primers, loading dye, nucleotides (dNTPs), Taq polymerase, mix buffer, and water. DNA sample is added to master mix. Components of PCR - Template, primers, taq polymerase, nucleotides, buffer template in PCR - the DNA from the sample specimen serves as the template for replication
