The major function of ribosomes is to synthesize?
The major function of ribosomes is to synthesize proteins by translating messenger RNA (mRNA) into amino acids. Ribosomes can be found in both prokaryotic and eukaryotic cells, and they are composed of two subunits - the large and small subunits.
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.
Which of the classes of RNA molecules is linked with proteins in forming the large and small subunits of a cytoplasmic structure?
Ribosomal RNA (rRNA) is the class of RNA molecules that is linked with proteins to form the large and small subunits of ribosomes, which are the cytoplasmic structures responsible for protein synthesis in cells.
Why ribosomes are of 70s in mitochondria of eukaryotic cell?
Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit.
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 is the meaning of 70S ribosomes in prokaryotes?
70S refers to the rate of sedimentation of the ribosome in a centrifuge. You can almost think of it as a unit of size. The "S" is a unit of measurement called the Svedberg unit. Ribosomes contain two subunits. In prokaryotes, these subunits are 50S (large) and 30S (small). The total ribosome with both subunits is 70S in prokaryotes. (Notice that 30 + 50 = 80 and not 70. Remember this is not size and the rate of sedimentation is less when the subunits are bound then when they are separated.) Eukaryotic cells have 80S ribosomes: 60S (large) and 40S (small) subunits.

Which structure is the assembly site of large and small ribosomal subunits?
The nucleolus is the assembly site of large and small ribosomal subunits. It is a structure inside the nucleus of a cell where ribosomal RNA (rRNA) and ribosomal proteins are synthesized and assembled into ribosomes.

Ribosomes are made up of two subunits?
There are two components.They are rRNA and proteins

What are very small organelles not bounded by a membrane and consist of a large and a small subunit?
Ribosomes http://en.wikipedia.org/wiki/Ribosome Although some can be membrane bound, not all are. Also, read the section on structure to see the info on the large/small subunits

Does rDNA form ribosomes?
Yes, rDNA does form ribosomal subunits. This occurs inside the nuclear membrane at an area called the nucleolus. Two subunits are formed consisting of a small (40S) and a large (60S) subunit. These subunits are then leave the nucleus and assemble in the cytoplasm or on the Rough Endoplasmic Reticulum.
What synthesize subunits that will be assembled into two part ribosomes in the cytoplasm?
Ribosomal RNA (rRNA) and ribosomal proteins are synthesized in the cytoplasm as separate subunits. These subunits are then transported to the nucleolus where they are assembled into small and large ribosomal subunits, which together form the functional ribosome.
