Primary Structure of DNA The sequence of nucleotide chains is the primary structure of DNA. The genetic information is stored in these channels, and while the skeleton is the same for everyone, the variation in information is found in the…
Transposable elements (TEs) are DNA sequences that can move from one location in the genome to another. They are also known as “jumping genes,” TEs can cause genetic variation and are found in the genomes of most organisms, from bacteria…
Penetrance refers to the proportion of individuals with a particular genotype (genetic makeup) able to exhibit the corresponding phenotype (observable traits or characteristics). In other words, it is the likelihood that a genetic variant will be expressed (as a particular…
The molecular structure of DNA is the ultimate clue to its ability to replicate, code for proteins, and undergo mutation Introduction DNA consists of a double-stranded helical structure. Both the strand are complementary to each other and bonded together by double…
Scientists at the National University of Singapore (NUS) have developed a unique low-cost way of cancer testing. This novel test, known as the Heatrich-BS assay, sequences clinical samples that have been heated in order to identify cancer-specific signals contained in…
Human cloning has been a controversial subject since Dolly the sheep was cloned in 1996. Arguments for and against it have snowballed since, and will probably continue for years to come. On one side are the people who are against…
Agoraphobia is a type of anxiety disorder in which an individual experiences intense fear or anxiety in certain situations. These situations are where the individual perceives it may be difficult or embarrassing to escape, or where help may not be…
Post-traumatic stress disorder (PTSD)[a] is a mental and behavioral disease that can arise after exposure to a traumatic incident, such as a sexual assault, battle, car accident, child abuse, domestic violence, or other threats to one\’s life. A person\’s thoughts and…
Stress can be defined as a response resulting from an individual’s perception of a threat, whether real or imagined. Over the past decade, more than 80 studies have examined the impact of stress on the immune system. A psychosomatic response…
