The chemiosmotic theory or Chemiosmotic hypothesis

Leave a Comment / BIOCHEMISTRY /

In 1961, chemiosmotic theory was proposed by Peter D. Mitchell, a British biochemist, that suggested an electrochemical link between phosphorylation and cellular respiration. Later, in 1978, he was awarded a Nobel prize for chemistry for his work on the mechanism of synthesis of ATP across the inner mitochondrial membrane in cells. The process of chemical

DNA Damage theories: Introduction, Theories, Mechanisms

Leave a Comment / MOLECULAR BIOLOGY /

Introduction: In mammals, aging is a complex process that is accompanied by a progressive degeneration of tissues and organs which results in the loss of the ability to retain normal homeostasis. Aging is caused by accumulated damage to DNA, RNA, proteins, and lipids which in turn inhibits the ability of the cell to function normally

Chloroplast Genome: The liverwort Marchantia polymorpha L.

Leave a Comment / GENETICS /

Introdcution: The liverwort Marchantia polymorpha L., is one of the model organisms representing a basal group of land plants. It is one of the common weeds that grows in nursery crop production and distributed widely around the world from tropical to arctic climates. Plant chloroplast genomes are far more structurally conserved than plant mitochondrial genomes.

Leave a Comment / MICROBIOLOGY /

Introduction: Type of contaminants: Microorganisms in Bioremediation: Aerobic bacteria Many of these bacteria grow in the presence of oxygen that use the contaminant as the sole source of carbon and energy. It degrades pesticides and hydrocarbons, both alkanes and polyaromatic compounds. Examples: Pseudomonas, Alcaligenes, Sphingomonas, Rhodococcus, and Mycobacterium Methanotrophs/ Methylotrophs Bacteria that convert methane into
