what is the logical explanation for contamination of human DNA with plant chromosomal DNA during plant chromosome preparation?

02 February 2013 1 6K Report

Microdissected plant chromosomal DNA was amplified by whole genome amplification PCR techniques; someone had human DNA contamination in the plant DNA. how and which stage the contamination occurred?

Habibul Islam

One possibility is the body fluid spill , skin shed or hair fall on chromosome slides been used for microdissection, Another case might be the above contaminants got in to same tube with the sample DNA used for PCR amplification.

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,
