For many decades, researchers were trying to uncover the role of normal tissues in the formation of a cancer or a tumor. Although many researchers believed that normal tissues initiate the formation of cancer cells, they fail to come up with an acceptable explanation. However...
What twin studies have taught researchers about epigenetics
By: Janet Grischy
Identical twins begin from the same zygote, the same combination of egg and sperm. Therefore they have identical DNA, giving them the same genetic makeup. Yet identical twins do not remain identical throughout life. Because they don’t, researchers study the differences that monozygotic twins...

Cancer development is something that has been researched for many decades and with the advent of genetic and molecular technologies, it is now possible to track down the origins of certain cancers with high degree of accuracy. However, several decades back, the scientists were left...

In chromosomal crossover, genetic exchange increases variation because the genes recombine to form another gene that is new. Only during phase 1 of meiosis, can the similar traits of the chromosome unite, making a variation. The farther apart the common traits of the chromosome are...
Effects of trisomy 13: Patau syndrome
By: Imonikhe Ahimie
Trisomy 13, also known as Patau syndrome or trisomy D, is a genetic disorder where the patient has 3 copies of the chromosome number 13 rather the usual 2 copies that most people have. The syndrome has been observed as far back as 1657 (Thomas...
