In a study published today (February 14) in Genome Research, researchers describe a new clock, composed of methylation sites in ribosomal DNA. This timekeeper is found in species as diverse as mice, ...

When Blackburn carried out sequencing experiments for the ribosomal DNA minichromosome, she was surprised to find that the telomeres of this structure contained 20-70 tandem copies of a simple ...

Hajun Kim, Taejoon Kwon, and Joo Hun Kang—from the Department of Biomedical Engineering at UNIST has unveiled a novel ...

RNA molecules differ from DNA molecules in several important ways ... these molecules make up about half of the ribosomal mass. The remaining mass consists of a number of proteins — nearly ...

The rRNA structures also provide binding sites for ribosomal proteins, which help stabilize the overall structure of the ribosome. One of the most remarkable features of rRNA is its catalytic activity ...

In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive ...

Only a tiny fraction of the bacterial DNA remained in the mitochondrion ... for the basic building blocks of the mitoribosomes—the ribosomal RNA and 82 ribosomal proteins—are encoded in ...

The following is a summary of “Diagnostic-avoiding Chlamydia trachomatis variants detected in cervical and endometrial ...

Messenger RNA (mRNA) carries the genetic information from DNA to the ribosomes, where proteins are synthesized. Transfer RNA (tRNA) and ribosomal RNA (rRNA) are involved in the translation of mRNA ...
