SUMMARY

Ribosomes are complexes composed of ribosomal RNA (rRNA) and proteins, not DNA. This discussion clarifies the misconception that ribosomes might be made of DNA, emphasizing that ribosomes play a crucial role in translating codons, which are sequences of three nucleotides. The distinction between RNA and DNA is highlighted, particularly noting that RNA contains an additional hydroxyl group compared to DNA. Understanding the composition and function of ribosomes is essential for grasping their role in protein synthesis.

PREREQUISITES
  • Basic understanding of molecular biology concepts
  • Familiarity with macromolecules, specifically proteins and nucleic acids
  • Knowledge of ribosomal structure and function
  • Understanding of codons and their role in translation
NEXT STEPS
  • Research the structure and function of ribosomal RNA (rRNA)
  • Study the process of translation in protein synthesis
  • Learn about the differences between RNA and DNA, focusing on their chemical structures
  • Explore the role of ribosomes in various cellular processes
USEFUL FOR

Students of molecular biology, educators teaching genetics, and researchers interested in protein synthesis mechanisms will benefit from this discussion.

Hi,

The question is the same as the title :

Are ribosomes complexes of protein and RNA?

I read that in a book and though I have no idea what ribosomes are made of I thought it did'nt make sense that they are complexes of protein and DNA.

Help?
 
Biology news on Phys.org
Yes.

What made you think that it didn't make sense?
 
I don't know. At that time it just seemed counter-intuitive. Anyway, thanks guys.
 
Well what didn't make sense to me was the thread title asked about RNA, but the details asked about DNA. Which did you actually mean?

Oh right. Now that you mention it, I realized that I misread DNA for RNA in the actual message after reading the title.
 
Yes,ribosomes are made of ribosomal RNA and proteins.The role of these two is to create chemical repulsion(and attraction) between the two parts that make up a ribosome(small and large one),they open up and close like a mouth,and on each bite they read a codon(sequence of three nucleotides).
 
They are proteins made of single stranded RNA (Ribonucleic Acid). RNA has one more oxygen molecule than DNA hence the name Deoxyribonucleic Acid.

Proteins and RNA are two different types of macromolecules. Neither is made of the other.

I wouldn't call it an oxygen 'molecule', rather a hydroxyl group (-OH) at the second carbon of the ribose sugar

Yes sorry I meant from RNA.
