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.
What is two types of ribosomes and mitochondria?
The difference between ribosomes of prokaryotes and eukaryotes is the structure of the ribosomes. Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit. Eukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit. In eukaryotes, the ribosomes may be classified as either 'free' or 'bound'. Free ribosomes may be found suspended in the cytosol whereas bound ribosomes are attached to endoplasmic reticulum (as such called rough endoplasmic reticulum).
Small two-part structures in a cell that make proteins?
ribosomes
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.
Which organelle is a small particle of RNA and protein?
Sounds as if you are speaking of the ribosomes.
Do eukaryotic cells contain small 70S ribosomes instead of large 80S ribosomes?
NO
What do ribosomes look Ike?
Ribosomes structures vary. Some however have a large subunit on the top and a small subunit on the bottom

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
Can DNA travel to the ribosome for protein synthesis?
No, as it is too large and long. The way it works is that only small parts (genes) are copied and then taken to the ribosomes.No, as it is too large and long. The way it works is that only small parts (genes) are copied and then taken to the ribosomes.

Why are ribosomes smaller in prokaryotes?
Ribosomes are smaller in prokaryotes because they have different sizes and structures compared to eukaryotic ribosomes. Prokaryotic ribosomes (70S) consist of a small 30S subunit and a large 50S subunit, while eukaryotic ribosomes (80S) have a small 40S subunit and a large 60S subunit. Additionally, the smaller size of prokaryotic ribosomes allows them to be more efficient in protein synthesis.
What size are ribosomes?
Ribosomes are small cellular structures, typically measuring about 20-30 nanometers in diameter. They are composed of a large and a small subunit, each with specific functions in protein synthesis within the cell.

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.
Is ribosomes a small shop?
No, ribosomes are not a small shop. Ribosomes are cellular structures found in all living cells that are responsible for protein synthesis. They are not physical stores or shops.
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.
