There are many misconceptions about breast cancer and its causes. In the late 1990s, rumors suggested that antiperspirants cause breast cancer. Even today, some retail sources continue to offer alternative underarm hygiene products that claim to reduce the risk of breast cancer. One viral e-mail claimed that by blocking perspiration, antiperspirants prevent the body from purging toxins, instead forcing the body to store the toxins in lymph nodes in the underarm area near breast tissue. The e-mail stated that men were less likely to develop breast cancer from antiperspirants because their underarm hair trapped most of the product away from direct contact with skin. And as men are less likely to shave their underarms, they are less likely to have shaving nicks through which antiperspirants can enter the body.Read the abstracts of the two articles for which URLs are provided below. Darbre, 2005: http://is.gd/pPLxwZ Darbre et al., 2004: https://www.ncbi.nlm.nih.gov/pubmed/14745841 From reading only the abstracts name two components of underarm deodorants and antiperspirants that have been identified as possible culprits in causing breast cancer. Possible culprits in causing breast cancer: 1. 2. Briefly comment on one strength and one weakness for each of the studies (consider sample size, control groups, and overall study design). 2005 Aluminum study  2004 Parabens study Strength: Weakness: Based on what you read in the abstracts do you think that use of antiperspirants or deodorants, or both, is a consistent risk factor for breast cancer? Has your opinion about underarm hygiene changed? Explain how and why your opinion has either changed or remained consistent, referring to the abstracts that you have reviewed.

Direct-to-consumer genetic testing is different than medical genetic testing in that direct-to-consumer genetic testing provides access to one’s genetic information without the involvement of a medical professional or health insurance company. 

What is the type of genetic test that is used to detect changes in embryos created using assisted reproductive techniques such as IVF?

What type of mutation is this in Question 25?

[1] are when a DNA segment of one kilobase or larger is present at a variable copy number in comparison to the reference genome, and encompass [2] nucleotides per genome than SNPs and are [3] likely to cause health problems than SNPs. Common CNV’s in humans are [4] such as Huntington’s disease and spinocerebellar ataxia. Huntington’s disease is caused by a trinucleotide repeat [5] the coding sequence of the gene, while Fragile X syndrome is caused by a trinucleotide-repeat in the [6] region of the gene. The proposed mechanism for trinucleotide-repeat diseases is [7] which is thought to happen more often in regions of repeat during the process of [8].

A recent study compared whole genome sequencing to PCR testing to detect the most common inherited neurological disorders and found that whole genome sequencing was slower and less efficient at detecting these common inherited neurological disorders.
