Pharmacogenetics is the study of how genetic differences affect a person's response to medicine. Pharmacogenetics is often used interchangeably with pharmacogenomics. Pharmacogenetic research and testing determine a person's ability to metabolize medicines and...
What is Polymerase Chain Reaction Testing? PCR stands for Polymerase Chain Reaction and may be called "molecular photocopying," as it's a technique used to "amplify," or copy, DNA segments. According to the National Institutes of Health's National Human Genome...
Barbara McClintock was born June 16, 1902 in Hartford, Connecticut. During high school, she developed a love of science and was determined to continue her studies at Cornell University studying agriculture, and in 1923, she received her BS in botany. McClintock...
Genetically Modified Organisms (GMO) foods are created in a laboratory through genetic modification and engineering. Non-Genetically Modified Organisms (Non-GMO) foods are those that have not been genetically modified. Many concerns regarding the safety of GMOs...
Explore the importance of DNA purification, the various methods used, and the critical factors that influence the quality and yield of purified DNA.
Genetics and genomics testing are tests that involve genetic material. Though similar, genetics and genomics are actually quite different. Genetics is the study of single genes and how they affect a person, while genomics is the study of all an organism's genes....
Genetic markers are bits of genetic material, like genes or a DNA sequence, that are easily identifiable and used in laboratories as a way to tell apart cells, individuals, and species. Gene markers are often used to research and study relationships between an...
Quantitative Polymerase Chain Reaction qPCR is a laboratory technique used to detect a specific DNA sequence or sequences. Quantitative Polymerase Chain Reaction qPCR is common in both scientific research and diagnostics for detecting the presence of...
A technique with the ability to both track and identify bacteria
Epigenetics is the study of changes or variations in gene expression that are caused by external factors switching the genes on and off, ultimately affecting how they are expressed. Epigenetic changes occur naturally though they can be influenced by age, lifestyle,...
DNA fingerprinting, also called DNA profiling, is a scientific technique that collects a specific DNA pattern, or profile, from an individual organism. Often the DNA profile is then compared to other profiles to find a match. DNA fingerprinting is most commonly...
A genetic marker is a gene whose location on a chromosome is known and can be used to identify a species. Genetic markers are divided into two groups, biochemical markers that can detect variations in proteins and amino acids, and molecular markers that detect DNA...
Chromosome analysis, also called karyotyping, is a test done to examine the chromosomes in a cell sample. Examining chromosomes in this manner helps identify any genetic causes of disease or disorder. Karyotype testing can be performed on cells or tissues such as...
