Ribosomes

• Ribosomes are cellular organelles responsible for protein synthesis in all living cells.
• They are composed of both protein and RNA (ribosomal RNA or rRNA), but they do not contain DNA.
• The ribosomes read the messenger RNA (mRNA) produced from DNA in the process of transcription and use it as a template to synthesize proteins during the process of translation.
• They play a critical role in the translation of genetic information from mRNA into proteins, which are essential for various cellular functions and structures.
