SCIENTISTS UNRAVEL THE MYSTERY OF THE PROTEIN FACTORY IN OUR CELLS
TOPIC: (GS3) SCIENCE AND TECHNOLOGY – SOURCE: SCIENCEDAILY
Scientists used electron microscopy to create a 3D model of a part of the human cell, specifically the ribosome.
Overview of Ribosomes
- Non-membrane-bound cell organelles composed of RNA and proteins.
- Present in both prokaryotic and eukaryotic cells.
- In eukaryotes, found in the cytoplasm, mitochondria, and chloroplast; in prokaryotes, located free in the cytoplasm.
Structure and Function of Ribosomes
- Made up of two subunits: large and small, comprising ribosomal RNA (rRNA) and proteins.
- Primary function: Complex molecular machines facilitating protein synthesis or translation.
Protein Synthesis Process
- Ribosomes read messenger RNA (mRNA) sequence.
- Translate genetic code into a specific string of amino acids, forming proteins.
- Newly formed proteins detach and move to other cell parts for use.
What is mRNA?
- Single-stranded RNA involved in protein synthesis.
- Produced from a DNA template during transcription.
- Carries protein information from DNA in the nucleus to the cell’s cytoplasm.
- mRNA sequence is read by cellular machinery, translating each three-base codon into corresponding amino acids in a growing protein chain.
Role of mRNA in Protein Synthesis
- mRNA acts as a form of nucleic acid, facilitating the reading of the human genome coded in DNA by the cellular machinery.
- In conclusion, the 3D model of ribosomes aids in understanding their intricate structure and their pivotal role in protein synthesis, crucial for the functioning of every cell in the body.
