Try to digest your RNA with "RNase-free DNase" and then perform qPCR. Hopefully, you would not have that unwanted peak

It may be due to residual genomic DNA in your RNA miniprep.

In Topic: Pen/Strep from Sigma unit confusion

It's 100X concentrate;
Streptomycin 10'000 μg/ml
Penicillin 10'000 Units/ml
By adding 1ml of this antibiotics solution to 100ml (99+1) medium you would have 100μg and 100 Units of Streptomycin and Penicillin, respectively.

you can also perform colony PCR using vector-insert primers to confirm correct orientation.

the efficiency of competent cells can't be deduced from these controls.
You would have to do a control transformation in order to rule out this possibility.
