The STR profile you just calculated used 6 loci.  Is this sufficient to identify whether this is a suspects DNA?  Why/ why not?

. Name two feature of PCR that make this technology useful in molecular diagnostics and forensics [2]2. a) What are STRs and what makes them useful in forensic science?b) What is the major difference between RFLPs and STR analysis?3. In microarray technology:a) What must the mRNA be converted to before it may be bound by specific nucleotide probes and howis this done?b) How would you control the stringency of hybridization?c) Name two limitation of this technology4. In qPCR, what is the Ct value used to quantify gene expression?[3][1][2][2][2][2]

What two characteristics does an STR locus need to have to be useful in DNA fingerprinting?

Pranjal is a junior researcher at a cell culture lab, and he requires a specialized cell line for one of his experiments. Fortunately, many frozen vials of the identical cell line stock are in the possession of his senior. However, the senior still won't give him the access to the cell vials despite repeated requests. Following many failed efforts, Pranjal was given one cell stock; nevertheless, he was curious, so he conducted a STR (Short-tandem repeat) profile to verify the legitimacy of that specific cell line and discovered that the senior had given him the incorrect cells. What action plan does he have? He should tweet about the incident on social media, and make others aware of an unethical incident happened in the research field He should speak with his supervisor first and seek assistance suspecting a research ethics issue He should immediately ask for an urgent lab- meet and discuss the issue in front of everyone while blaming the senior He ought to relocate the lab and look for a more suitable space to work in.
