What are ribosomes made up of?
Ribosomes are made up of ribosomal RNA (rRNA) and proteins. They consist of two subunits that come together to build proteins based on the instructions provided by messenger RNA (mRNA).
What two things make up ribosomes and are are ribosomes surrounded by membrane like other organelles?
Ribosomes are not membrane bound, they are free cytoplasmic organelles responsible for the translation of cytoplasmic mRNA's. When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become "membrane-bound". In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the "rough ER". The newly produced polypeptide chains are inserted directly into the ER by the ribosome and are then transported to their destinations. Ribosome in eukaryotes are called 80S ribosomes and consist of a small 40S subunit and a larger 60S subunit. Prokaryotes have 70S ribosomes consisting of a 30S and 50S subunits. Hope this helps.
Is there a membrane in a ribosome?
No, ribosomes are not membrane-bound organelles like others.
What organelle produces ribosomes?
The nucleolus is responsible for producing ribosomes in a cell. It is a small structure located inside the nucleus and plays a crucial role in the synthesis of ribosomal RNA and assembly of ribosomal subunits.
Characteristics of ribosomes?
Ribosomes are cellular organelles that are responsible for protein synthesis in all living organisms. They are composed of two subunits and can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes are made up of RNA and proteins, and they translate genetic information from mRNA into functional proteins.
What is made of protein and r-RNA?
Ribosomes. Ribosomes are made up of two subunits, each of those are made up of strands of rRNA and protiens.
What are ribosomes shaped like?
Ribosomes are made of two subunits; one larger and one smaller. It is made up of proteins and has a globular shape. This is so that mRNA can pass through during translation.
Which are the major components of ribosomes?
Ribosomes are composed of two subunits: a large subunit and a small subunit. These subunits are made up of ribosomal RNA (rRNA) and proteins. The rRNA plays a crucial role in catalyzing protein synthesis, while the proteins help stabilize the structure of the ribosome.
What are ribosomes made up of?
Ribosomes are made up of ribosomal RNA (rRNA) and proteins. They consist of two subunits that come together to build proteins based on the instructions provided by messenger RNA (mRNA).
What is manufactures ribosomes?
Ribosomes are primarily manufactured in the nucleolus of a cell. Ribosomal RNA (rRNA) and ribosomal proteins are assembled together in the nucleolus to form small and large subunits of ribosomes. These subunits then exit the nucleus and come together to form functional ribosomes in the cytoplasm.
What materials make ribosomes?
Ribosomes have two parts to it. They have 2 subunits and their main function is to synthesize proteins. Ribosomes can either be found floating around in the cytoplasm or be attached to the endoplasmic reticulum. All types of cells contain ribosomes.

Is there a membrane in a ribosome?
No, ribosomes are not membrane-bound organelles like others.
Is ribosomes composed of protein?
Yes, ribosomes are composed of both protein and RNA molecules. The protein components constitute about two-thirds of the ribosome's mass, while the RNA molecules are involved in the catalytic functions of protein synthesis within the ribosome.

What subunits are present in carbohydrates?
Carbohydrates, Cx(H2O)y, are made up of two subunits, carbon (Cx) and water (H2O)y, where x and y are the number of molecules in each of the subunits.
