Meechaiel Criner's defense has been arguing this week that a new software the Department of Public Safety used to analyze DNA evidence is not reliable.

The judge has to allow the DNA into the trial.
The defense will file motions to get it excluded. There could be a Daubert hearing contesting the prosecution's expert DNA witness or witnesses.
I saw a Daubert hearing last year, defense was trying to get shoe print expert testimony excluded.
So if DNA testimony gets before the jury then both sides will have experts to explain the DNA evidence. Prosecutors will want their expert(s) to convince the jury that Kohberger's DNA is on the sheath and he - Kohberger - put it there.
Defense will want jury to believe that there is reasonable doubt that this is even Kohberger's DNA.
Juries convict more often when they believe in the DNA evidence.
