Some enzymes can chew through synthetic polymers. Researchers would like to harness this ability to etch channels, trenches, and holes into biocompatible materials as a way to fabricate drug delivery ...

Genomic DNA is modified by chemical markers, which can change gene expression without altering the underlying genetic code. These so-called epigenetic tags (described in the videos) can also mark DNA ...

Soil extracellular enzymes catalyze soil biochemical processes, and the geographical patterns of their activities and stoichiometry can reflect soil microbial functional dynamics. In previous research ...

Enzymes are the molecular machines that power life; they build and break down molecules, copy DNA, digest food, and drive ...

Mycelial extracts from five isolates of Thamnidium elegans and two isolates of T. anomalum were examined by starch gel zymography for ten different enzyme activities. Although enzyme patterns were ...

Investigation of the electrophoretic characteristics of NADH methemoglobin reductase in five unrelated families with a deficiency of this enzyme showed three different types of enzyme patterns: total ...

Sugars known as glycans form dense envelopes around cells. But they’re often ignored in biological investigations because, unlike DNA, proteins and other cellular components, tools to study them are ...

A survey was conducted to study the genetic differentiation among 16 tribal groups of Orissa, Madhya Pradesh, and Maharashtra belonging to different ethnic and linguistic affiliations. Sixteen hundred ...

The results revealed a clear sequence. Enzymes predating cannabis showed no ability to process CBGA. The first enzyme unique ...

Scientists have long assumed that once the smooth cartilage in a damaged knee wears away, the body has little chance of ...
