RNA molecules can be modified by enzymes through the addition or removal of chemical groups, but the roles of these modifications in the regulation of both mRNAs and non-coding RNAs are not fully ...

Professor Zhou's research group focuses on developing and applying new technologies to visualize spatial and temporal distributions of chemical modifications in the mammalian transcriptome at ...

Genetic information encoded in genomic DNA is transcribed to mRNAs and then the codons on mRNA are decoded by transfer RNAs (tRNAs) during protein synthesis. tRNAs deliver amino acids to ribosomes and ...

Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but ...

A groundbreaking study has shed light on the critical role of a tRNA methylation enzyme, TRMT10A, in supporting brain function. The findings reveal how the absence of TRMT10A leads to a reduction in ...

In eukaryotes, there are four rRNAs associated with ribosomes; these are the 18S, 5.8S, 28s, and 5S rRNAs. Production of the first three occurs within the nucleolus, whereas 5S rRNA production occurs ...

The ribosome, that protein-making machine, relies on other, smaller machines. For example, it works in concert with a mechanism that supplies amino-acid-carrying tRNAs, including tRNAs that require ...

A new advanced, high-throughput sequencing technique should enable scientists to have a firmer grasp on the activity of naturally occurring microbiomes in response to real-world conditions and diet.

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...
