STONY BROOK, NY / ACCESS Newswire / June 16, 2025 / Applied DNA Sciences, Inc. (NASDAQ:APDN) (“Applied DNA” or the “Company”), a leader in PCR-based DNA technologies, today announced that it will ...

However, DNA polymerase cannot begin forming this new chain on its own and can only add nucleotides to a pre-existing 3'-OH group. A primer is therefore needed, at which nucleotides can be added.

To determine where DNA polymerase was and what it was doing, Xu and his colleagues combined two methods: confocal microscopy and optical tweezers. The team stretched an 8,000 kilobase strand of DNA ...

Prokaryotes contain five different types of DNA polymerase. These are described below. Polymerase I is a DNA repair enzyme from the family A polymerases that has a 5’ to 3’ and 3’ to 5 ...

This study reveals that RNA polymerase I uses a unique stalling mechanism at abasic DNA sites, distinct from RNA polymerase II. Pol I’s tendency to stall prevents the production of defective ...

Many researchers have attempted to tackle this challenge, but they have had limited success. Recently, at the International Symposium on Human Identification (ISHI), scientists at Promega Corporation ...

What am I looking at? This is a 3D rendering of an RNA polymerase II enzyme from baker’s yeast, created using actual molecular data to reconstruct its shape and active sites. What looks like a ...
