DNA Polymerase News and Research

RSS

A DNA polymerase is an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand. DNA polymerases are most well-known for their role in DNA replication, in which the polymerase "reads" an intact DNA strand as a template and uses it to synthesize the new strand. The newly-polymerized molecule is complementary to the template strand and identical to the template's original partner strand. DNA polymerases use a magnesium ion for catalytic activity.

Researchers discover new human enzyme that facilitates DNA repair during DNA copying process

Every day, the human body produces new cells to regenerate tissues and repair those that have suffered injury. Each time this happens, the cells make copies of their DNA that they will pass on to the resulting daughter cells. This process of copying the DNA, also called replication, is very delicate, given that it can generate severe alterations in the DNA that are associated with malignant transformation or ageing.

Scientists discover new details of biochemical interactions necessary for cell division

Building on earlier work exploring the complex choreography by which intricate cellular proteins interact with and copy DNA prior to cell division, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators have captured a key step-molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target.

DNA synthesis in the 3’ and 5’ direction possible using new template-directed method

When a cell divides, it passes on genetic information by producing copies of its DNA. Chemists have also learned to copy DNA. In the journal Angewandte Chemie, a German team has now introduced a new copying technique that uses a single strand of DNA as the “master copy”, like a cell, but does not require enzymes.

Researchers decode and characterize DNA repair mechanism

Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes. It occurs when the body is exposed to excessive amounts of electrically charged, aggressive oxygen compounds. These are normally produced during breathing and other metabolic processes, but also in the case of ongoing stress, exposure to UV light or X-rays. If the oxidative stress is too high, it overwhelms the body's natural defences. The aggressive oxygen compounds destroy genetic material, resulting in what are referred to as harmful 8-oxo-guanine base mutations in the DNA.
