A polysome is a group of ribosomes reading a an mRNA transcript in the cytosol not bound to an endoplasmic reticulum whereas a Ribosome is the single structure that could or could not be reading an mRNA transcript at any given time. Free ribosomes tend to hang out on endoplasmic reticulum(ER), making that ER rough, giving it the name rough endoplasmic reticulum. Polysomes also tend to make cytosolic proteins that will usually remain inside of the cell, whereas ribososmes on the RER will make proteins into the leumen of the ER they are bound to...to be futher modified and sent to the Golgi to be packaged and enevtually secreted (sent outside of the cell)

What is the difference between a bacterial rIbosome and a eukaryotic ribosome?
Bacteria have 70s ribosomes.Eukariyotes have 80s ribosomes
A polysome is?
A polysome is numerous ribosomes simultaneously translating the same mRNA.
What is the difference between centrosome and ribosome?
Ribosomes are necessary for protein synthesis and centrosomes are used in cell division. Plants do not have centrosomes.
What are ribosomes in humans?
There can be as many as 10 million ribosomes in one cell. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome. I LIKE FOOD>
What is a free ribosome?
A free ribosome is a ribosome that is not attached to the rough endoplasmic reticulum and is thus suspended in the cytoplasm.
What is the difference between a bacterial rIbosome and a eukaryotic ribosome?
Bacteria have 70s ribosomes.Eukariyotes have 80s ribosomes
A polysome is?
A polysome is numerous ribosomes simultaneously translating the same mRNA.
Difference between prokaryotic ribosome and eukaryotic ribosome?
in prokaryotic cell ribosome is partly synthesised from nucleoid and partly from pre-exsisting ribosomes. in eukaryotic cell ribosomes are partly synthesised from nucleorar organiser region and partly from pre-exsisting ribosomes.
What is the difference between centrosome and ribosome?
Ribosomes are necessary for protein synthesis and centrosomes are used in cell division. Plants do not have centrosomes.
What leads to the self destruction of a cell?
polysome
What is the term for a group of ribosomes on one mRNA chain?
Polysome.
What will happen after the ribosome joins the methionine and phenylalanine?
The ribosome breaks he bond between methionine and it's tRNA. The tRNA floats away from the ribosome, allowing the ribosome to bend to another tRNA. The ribosome moves along the mRNA, binding new tRNA molecules and amino acids.
When many ribosoms atteched to a singal RNA calld?
It is called a polysome.
What is the difference between an organelle and an organism?
An organ is a collection of cells that perform a function (liver, skin, muscles) whereas an organelle is something INSIDE a cell which performs a function for the cell (ribosome, mitochondria)
Discuss the difference between a membranous organelle and a nonmembranous organelle?
Membranous: endoplasmic reticulum, Golgi apparatus, lysosome, mitochondrion, plasma membrane, nucleus. Nonmembranous: centriole, nucleolus, ribosome. The difference between these two: Membranous has a definite boundary created by a membrane whereas a nonmembranous is an organelle without a specific boundary.
What organelle are proteins synthesized with?
It is the ribosome. Proteins are synthesized on that
What is the Difference between organelle and organ system?
An organ is a collection of cells that perform a function (liver, skin, muscles) whereas an organelle is something INSIDE a cell which performs a function for the cell (ribosome, mitochondria)
