Summary
The ribosome, a complex of RNA and protein, synthesizes proteins in all active cells. Recent studies highlight the crucial role of ribosomal RNA in its function, suggesting proteins evolved later.
Area of Science:
- Molecular Biology
- Structural Biology
- Biochemistry
Background:
- The ribosome is a fundamental cellular machine responsible for protein synthesis.
- It is composed of ribosomal RNA (rRNA) and ribosomal proteins.
- Understanding the ribosome's structure and function is key to deciphering cellular processes.
Purpose of the Study:
- To investigate the functional significance of the ribosome's RNA component.
- To provide structural insights into the ribosome's catalytic activity.
- To evaluate the evolutionary hypothesis regarding the late addition of proteins to the ribosome.
Main Methods:
- Recent structural analyses of the ribosome.
- Biochemical assays to assess RNA-protein interactions.
- Comparative evolutionary studies.
Main Results:
- Structural data reveal extensive involvement of ribosomal RNA in all functional aspects.
- The RNA component plays a central role in catalysis and substrate binding.
- Evidence supports the hypothesis of a protein-late, RNA-early ribosome evolution.
Conclusions:
- The ribosome's RNA is the primary functional and catalytic core.
- Ribosomal proteins likely evolved to stabilize and modulate the RNA core.
- This supports an RNA-centric view of early ribosome evolution.

02:43Nucleic acids
Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes, the...

01:23Types of RNA
Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

01:25Nucleic Acid Structure
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.
