Sometimes, ribosomes are visible as clusters, called polyribosomes. In eukaryotes (but not in prokaryotes), some of the ribosomes are attached to internal membranes, where they synthesize the ...

The ribosome is a large molecular complex of RNA and protein. When eukaryotic ribosomes are isolated from cell extracts, two different fractions are obtained, representing two subunits. The smaller ...

Ribosomes, the cellular machines responsible for protein synthesis, are essential for all living organisms. Prokaryotic cells ...

The idea for the study stemmed from recent reports that eukaryotes appear to have heterogeneity among their ribosomes, study coauthor Xuejiang Guo, a reproductive biologist at Nanjing Medical ...

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA.

Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...

Cytoplasm, ribosomes present; there are no mitochondria or chloroplasts. Genetic material DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule ...

where they allow the replication of viruses in infected cells by recruiting host ribosomes. In recent decades, however, more and more IRESes have also been described in eukaryotic cells ...

Structural studies in his group on bacterial and eukaryotic ribosomes and their functional complexes, using a combination of crystallographic, electron microscopic and biochemical experiments, have ...

Ribosomal RNA (rRNA) is a component of the ribosomes, the cellular machinery responsible for ... The resulting primary transcript, known as pre-mRNA in eukaryotes, undergoes several processing steps ...
