Discussion Overview

The discussion centers around the composition of ribosomes, specifically whether they are complexes of protein and RNA. Participants explore the definitions and distinctions between RNA and DNA, as well as the structural and functional aspects of ribosomes.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions the statement that ribosomes are complexes of protein and DNA, expressing confusion about the terminology used in the original question.
  • Another participant clarifies that ribosomes are indeed made of ribosomal RNA and proteins, describing their roles in ribosome function.
  • Several participants note the distinction between RNA and DNA, with one emphasizing that proteins and RNA are different types of macromolecules.
  • There is a correction regarding the terminology used to describe the chemical structure of RNA compared to DNA, specifically regarding the presence of a hydroxyl group.

Areas of Agreement / Disagreement

Participants generally agree that ribosomes are made of RNA and proteins, but there is some confusion regarding the initial question about DNA. The discussion includes multiple viewpoints on the details of ribosome composition and structure.

Contextual Notes

Some participants express uncertainty about the definitions and roles of RNA and DNA, and there are unresolved questions regarding the clarity of the original inquiry.

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.
