Web1 Jul 2015 · The percentage transfer of DNA to the tertiary substrate is the amount of DNA found on the tertiary substrate divided by the amount found on the secondary and tertiary substrate, (s3/s2 + s3). The average total DNA quantity deposited during primary transfer to s1 and the average percentage transfer to s2 and s3 are presented in Table 1. WebHowever, what if we have secondary and perhaps then tertiary DNA transfer. So some of that biological material on surface or exhibit 1 transfers onto someone else’s hand or gloves and then is transferred onto another item. That DNA on item 2 will still give that same DNA profile. And we would likewise be able to assign a very strong ...
