Scientists from Cardiff University’s School of Biosciences reported that a father’s gene may have an impact on the quality of care that is furnished by the mother to her newborn offspring. One of the most crucial roles of a mother is being able to provide and attend to the needs of her offspring, especially during…

A recent finding by a team of researchers from European Molecular Biology Laboratory on the parental chromosomes during the first mitosis of an embryo implicates a possible revision in biology textbooks. What they observed during the first mitotic division after the supposed “union” of gametes in mouse models apparently invalidates what is currently believed. Biologists…

Colon Cancer is the third most deadly cancer worldwide. There were more than 1.4 million cases each year and 694,000 deaths globally. The treatment of colon cancer includes chemotherapy, surgery and radiation therapy. However, advances in diagnosis and treatment leads to development and improvement in survival. Numerous data point out that genetic changes function as…

Aflatoxins produced by a certain molds that are poisonous carcinogens which grow mostly in soil, hay, decaying plants and grains. It can affect livestock and human as natural contaminants in foods like peanuts and corn meal. There are four types of aflatoxins these are B1, B2, G1 and G2 in which all are teratogenic, carcinogenic…

DNA repair strategies – overview DNA is crucial to life. It carries the fundamental blueprint for the proper functioning of a cell. Thus, a damaged DNA could indicate trouble. A mere structural change could lead to the disruption of the genetic code crucial to the building of proteins. Without an apt and prompt DNA repair,…

CRISPR as a gene editing tool made a prodigious leap forward in science. In 2015, it was heralded as Science’s 2015 Breakthrough of the Year.1 It stymied other impressive contenders like Ebola vaccine. It supersedes other gene-editing predecessors, such as TALENs (transcription activator-like effector nucleases) and ZFNs (zinc finger nucleases). Unlike these two, CRISPR does…

Butterflies are flying colored wing insects that vary in color and pattern from individual to another individual. It has wings covered with overlapping rows of scales. Most of butterflies have developed mechanisms to   avoid predators making disguise coloration blending like leaf or bark of the tree. Some releases chemicals as a defense mechanism wherein butterfly…

You probably already heard the concepts of translation in the central dogma of molecular biology. The dogma is an elucidation as to how a protein is born based on what the DNA holds. Based on it, the scheme begins at the DNA molecule being transcribed into RNA in a process called transcription, which is then…

Jumping genes, also known as transposons, are gaining momentum. They are considered either as slacking junks or maleficent parasites in our genome. As such, they are largely taken for granted. However, it seems the tables have turned. There seem to be certain jumping genes that without them we would not move past our embryonic state.…
