DNA Chapter Summary

1. A Question you had about the readings

When reading chapter 11 in the text about DNA, it seemed that there was no mention of Chimera. Chimera is believed to occur when fraternal twins fuse in the womb, leaving one person with more than a set of DNA.

It is fascinating to know that there are exceptions to DNA.

As the body breaks down the presence of microorganisms such as bacteria and fungi followed by a series of arthropods (Houck & Siegel, 2010). Insects influence human decomposition, and through each of the five stages of decomposition, invite different insects. Entomologist is able to

The most interesting aspect was the Chamberlin case and the reversal of the interpretation of evidence that resulted in the release of the Lindy Chamberlain (Houck & Siegel, 2010). It begs us to consider the power of evidence and the ability of law enforcement to misinterpret the results. Not only are innocent people convicted, most importantly guilty people can go free. Just think chocolate milk could render a false positive for chocolate milk. Perhaps now DNA could decipher the difference between cattle and human samples, it is the knowledge that evidence can be swayed by a person’s opinion without serving the truth. This story heightened the relevance of specimen collection, testing, and
