# Designing mitochondrial baits

36
We will consider the two mitochondrial genomes available in NCBI (see behind).

We will target less conservative regions in both intragenic and coding genes.

Baits will be designed as **180 base pairs length**, spread across the entire mitochondrial genome (no overlapping sequences as no need for a mitochondrial assembly).
As the mitochondiral genome of ***Rana temporaria*** is about 16,000 bp, a total of about **90 baits will be designed**.
We will synthetize the baits using a new technology for de-novo DNA synthesis available in [TWIST](https://www.twistbioscience.com/). 
We will be receive the baits in one unique tube.

# Hybridization baits and sequencing

47
Baits will be received as DNA but will be soon transformed in RNA (to facilitate the hybridization) based on the same step described in the hyRAD protocol.
Hybridation will allow **5 to 10% of divergence** between the DNA and the baits sequence, allowing 9 SNPs per sequence captured at the maximum.

Specificity of baits will be adjusted regarding the temperature of the hybridization.

The removal of non ***Rana temporaria*** sequences will be done by a post informatic treatment and by sequencing on Miseq our eDNA samples, to screen for other species present in the eDNA sample.
