Answer #1

Biomarker is generally used in the term for diagnosis of a disease. Where for example to know about the gene responsible for cause of disease, with the help of a biomarker it is able to identify. That is to know the location of the gene or to know the levels or condition about the disease.

In the case of a disease cancer there are several biomarkers BRCA are one of the biomarker for breast cancer and many markers used some in the form of DNA sequences in case of translocation or deletion where the reason behind the disease is easily found out. Mainly used in molecular biology and genomic studies of various disease.

Not only gene sequence but also like proteins, blood pressure and LDL levels can also act as biomarkers.

These all biomarkers are used for diagnosis and prognosis of a disease.

One of the most common screening tests for epithelial ovarian cancer involves the use of biomarkers. Biomarkers have been applied in the management of epithelial ovarian cancer in several different ways, including predicting primary disease at an early stage, distinguishing malignant from benign pelvic masses, monitoring responses to treatment, and estimating prognosis. A number of proteins present in either blood or urine have been identified as specific markers for epithelial ovarian cancer. Let’s say that you collected data from patients...

The half-life of nicotine in most humans is about 2 hrs, whereas the half-life of cotinine, a by-product of nicotine that is a used as a biomarker for tobacco use, is 20 hrs. Assuming there is a concentration of 20 µM for both substances in your bloodstream after tobacco use (t0), and the detection limit for both substances is 1 µM, how long would it be before nicotine and cotinine are undetectable?
