What have we learned about RNA structure and function so far ... these rRNA genes to be able to manufacture the large number of ribosomes required by a cell. Mature rRNAs are produced by cleavage ...

Ribosomes are composed of two subunits ... The rRNA structures also provide binding sites for ribosomal proteins, which help stabilize the overall structure of the ribosome. One of the most remarkable ...

Ribosomes undergo changes in conformational state, striking different, well-orchestrated poses that allow strands of RNA to be fed through the structure's two subunits where instructions carried ...

Their cell structure is simpler than the cells of animals ... Cell contents Cytoplasm, cell organelles include mitochondria, ribosomes and chloroplasts in plants. Cytoplasm, ribosomes present ...

We think the bacteria's ribosomes might be altering its structure just enough to prevent an antibiotic from binding effectively." Anna Delgado-Tejedor, first author of the study and PhD student at ...
