同时,李志刚主任在大会就ctDNA检测用于食管癌新辅助治疗后的疗效评估应用作了题为“Circulating tumor DNA (ctDNA) analysis for detection of residual disease after neoadjuvant chemoradiotherapy (nCRT) for esophageal squamous cell carcinoma ...
Where does agarose come from and what is it about the structure of agarose that makes it useful in electrophoresis? What is the MAIN purpose of running the PCR samples on an agarose gel using electrophoresis? a. to separate the DNA products by their length (in base pairs). b. to...
What is the purpose of doing the No DNA control? Variables: Variables are factors that are manipulated in the experiment. The independent variable is what the experimenter changes, and the dependent variable is what they measure. There are also control variables to ensure reliability and validity ...
Process of PCR: PCR, or polymerase chain reaction, occurs in three distinct steps: denaturation, annealing and extension. The process helps synthesize several copies of a single DNA or RNA sample. Answer and Explanation: Learn more about this topic: ...
What is an important use of PCR in biotechnology? Give examples. What does RNase do to gel electrophoresis? How does DNA ligase work? What is DNA electrophoresis used for? Why do smaller molecules move faster in gel electrophoresi...
What does PCR stand for? What is the purpose of perform PCR reaction? Why did you need to perform the DNA extraction technique(Part I of this lab activity)prior to performing the PCR technique? What is the first substance that you added to...
Using PCR-based genotyping of autosomal short tandem repeats, we were able to obtain reliable and reproducible DNA profiles in 163 out of 616 criminal cases (26.5%) and in 283 out of 4,085 individual CBC items (6.9%) during the period January 2003–December 2009. We discuss practical ...
PCR DNA replicationimprovement trajectoryAs an effort to peek into the black box of large-scale general purpose technologies (GPTs) like biotechnology and information technology, we develop the concept of 'anchor technologies'. An anchor technology is a core technology of a large-scale GPT ('mega...
TIB Molbiol is a German laboratory based in Berlin. This lab was the first provider of synthetic DNA and of multiplex PCR tests for different viruses including COVID-19. They have been relying on DHL Express for supplying the world with these tests during the pandemic and ha...
Why is DNA polymerase used in PCR? What are the advantages to having DNA, RNA, and protein compared to only RNA? What are the evolutionary reasons for using RNA as an intermediate in the process of protein synthesis? Explain the mechanism of serine...
