How to Be DNA/RNA Extraction Technician - Job Description, Skills, and Interview Questions

DNA/RNA extraction is a crucial step in genetic research and biotechnology, as it is the starting point for many techniques. The process involves isolating DNA and/or RNA molecules from a sample, such as a cell or tissue, so that they can be further studied in the laboratory. The success of the extraction procedure depends on the technician's expertise and skills in selecting the appropriate method and equipment for the specific sample, as well as their ability to follow the relevant protocols.

If done correctly, the extracted DNA and/or RNA can be used for a range of applications, such as gene cloning, amplification and sequencing, as well as for diagnostics and forensics. However, if the extraction is not done properly, the results can be compromised, leading to inaccurate results and wasted resources. Therefore, having a skilled and experienced DNA/RNA extraction technician is essential for any lab that wants to produce reliable results.
