TAMU bio 111 lab exam 2 review (2023/2024) already passed 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 such as gene transcription. What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can...

Since December of 2000, the Central Public Health Laboratory (CPHL) of the Ontario Public Health Laboratories, Ministry of Health and Long-Term Care has utilized an inhouse nucleic acid amplification testing followed by Sanger sequencing for the detection of Mycobacterium tuberculosis complex (MTBC) in formalin-fixed paraffinimbedded tissue specimens. Although this methodology has allowed for the characterization of approximately 250 tissue specimens, it is labor intensive and requires t...
