AMT Molecular Diagnostics Technologist (MDT) Certification Questions and answers latest update

What does AMT stand for in the context of the MDT certification? American Medical Technologists What is the primary purpose of the AMT MDT certification? To validate the knowledge and competence of professionals working in molecular diagnostics laboratories. What is the minimum educational requirement to sit for the MDT exam? A bachelor’s degree or higher from an accredited institution in a biological or chemical science. How many years of work experience are typically required to take the MDT exam if the applicant has a bachelor’s degree? One year of full-time experience in a molecular diagnostics laboratory. What alternative pathway exists for medical technologists already certified by AMT to add the MDT credential? They can take the MDT examination if they have documented molecular experience, or complete a molecular diagnostics training program. Which regulatory framework ensures quality standards in clinical molecular laboratories? CLIA (Clinical Laboratory Improvement Amendments) What is the role of the College of American Pathologists (CAP) in molecular diagnostics? CAP provides accreditation and proficiency testing programs for molecular laboratories. What type of nucleic acid is DNA? Deoxyribonucleic acid What type of sugar is found in DNA? DeoxyriboseWhat nitrogenous bases are found in DNA? Adenine, guanine, cytosine, and thymine How do the bases pair in double-stranded DNA? Adenine pairs with thymine, and cytosine pairs with guanine. What is the sugar component of RNA? Ribose Which base replaces thymine in RNA? Uracil What is the primary function of messenger RNA (mRNA)? To carry genetic coding information from DNA to ribosomes for protein synthesis. What does ribosomal RNA (rRNA) do? It forms the core of the ribosome and catalyzes protein synthesis. What is the function of transfer RNA (tRNA)? To bring amino acids to the ribosome during translation. What is a gene? A segment of DNA that contains the instructions for making a specific protein or RNA molecule. What is an exon? A coding region of a gene that is retained in the mature mRNA. What is an intron? A non-coding region of a gene that is removed during RNA splicing. What is the central dogma of molecular biology? DNA is transcribed into RNA, which is translated into protein. What is a mutation? A permanent change in the DNA sequence. What is a point mutation? A change in a single nucleotide base pair. What is a nonsense mutation? A mutation that creates a premature stop codon.What is a missense mutation? A mutation that changes one amino acid to another. What is a frameshift mutation? An insertion or deletion that alters the reading frame of the gene. What is a silent mutation? A mutation that does not change the amino acid sequence of the protein. What is a polymorphism? A common variation in DNA sequence that occurs in at least 1% of the population
