Within bioinformatics this generally refers to problems with wet-lab procedure, please see detailed explanation. In biological system, it refers to the process of mutation generation involving the DNA polymerase enzyme.
'Errors' in bioinformatics refers to wet-lab data robustness because generally 'errors' in code are referred to as 'bugs', although major faults in code could be termed 'errors'. 'Errors' can refer to misincorporation of the wrong nucleotide base when the DNA polymerase is copying a molecular of DNA and results in a mutation.
