DNA and fingerprint technology is said to be very accurate as it uses chemicals to separate strands of your own unique DNA to reveal the unique parts of your genome. which is your genetic make-up
This technology emerged in 1984 and invented by Professor Sir Alec Jeffreys who realized that you could detect variations in human DNA, in the form of these mini-satellites to produce a pattern unique to an individual
Human error still plays a role in terms of lab staff who make errors in conducting the DNA analysis, interpreting it or reporting the results of the analysis sometimes it occurs in entering the resulting DNA profile into a DNA database system which may result from a failure to comply a procedure, misjudgement, or some other mistake. There are protocols and precautions which can be introduced to minimise the opportunity for error during analysis or interpretation, however, the potential for human error cannot be fully eliminated.
Two branchial hearts pump blood through each of the two gills, while the third is a systemic heart that pumps blood through the body. Octopus blood contains the copper-rich protein hemocyanin for transporting oxygen.
