For instance, bacteria contain a single type of RNA polymerase, while eukaryotes (multicellular organisms and yeasts) contain three distinct types. In spite of these differences, there are ...

Bacteria have an interesting answer ... the formation of this kind of secondary structure in RNA upstream of RNA polymerase can lead to dissolution of the RNA polymerase/DNA complex (Gusarov ...

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it ...

There are a variety of different types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is responsible for creating messenger RNA (mRNA), which is the main ...

This cat-RNA was introduced into a model microbial community using conjugative plasmids, which are naturally occurring gene carriers in bacteria. The experiment involved introducing these ...

Vancomycin 265/309 (85.8%) 76/265 (25.3%) 198/309 (64.1%) † Clinical cure is resolution of diarrhea following the recommended dose of drug (fidaxomicin: 200 mg twice a day; vancomycin: 125 mg ...

In a paper published today (August 15) in PNAS, scientists from the Scripps Research Institute in La Jolla, California, report on their use of in vitro evolution to generate an improved polymerase ...

The team analyzed 19,885 known genetic sequences of 14,614 species of bacteria, then designed species-specific PNA sequences to target the bug's ribosomal RNA. PNA probes have distinct advantages ...

Scientists at the UCLA Health Jonsson Comprehensive Cancer Center and the University of Toronto have revealed how a tiny chemical modification in RNA, known as m6A, plays a critical role in the ...

Rather, this method harnesses the dual catalytic activities of Vaccinia t The researcher first PCR-amplifies the gene or gene segment of interest using a proofreading polymerase and primers that ...

These products are often proteins, but in non-protein coding genes such as rRNA genes or tRNA genes, the product is a functional RNA. Several steps in the gene expression process may be modulated ...
