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 else can I help you with?
A polysome is?
A polysome is numerous ribosomes simultaneously translating the same mRNA.
What is the difference between a bacterial rIbosome and a eukaryotic ribosome?
Bacterial ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S). Additionally, bacterial ribosomes have fewer proteins and do not have as many modification sites as eukaryotic ribosomes. The antibiotic targeting sites also differ between bacterial and eukaryotic ribosomes.
Can more than one ribosome at a time translate an mRNA transcript?
Yes because the ribosomes are made in the cytoplasm which allows the RNA polymerase to detect the transcrpt
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 hold the ribosomes together in polysomes?
When several ribosomes are attached to one mRNA strip it is called polysome.So, mRNA holds together the ribosomes in a polysome.
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.
A polysome is?
A polysome is numerous ribosomes simultaneously translating the same mRNA.
What leads to the self destruction of a cell?
polysome
What is the term for a group of ribosomes on one mRNA chain?
Polysome.
When many ribosoms atteched to a singal RNA calld?
It is called a polysome.
What is the difference between a bacterial rIbosome and a eukaryotic ribosome?
Bacterial ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S). Additionally, bacterial ribosomes have fewer proteins and do not have as many modification sites as eukaryotic ribosomes. The antibiotic targeting sites also differ between bacterial and eukaryotic ribosomes.
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)
Can more than one ribosome at a time translate an mRNA transcript?
Yes because the ribosomes are made in the cytoplasm which allows the RNA polymerase to detect the transcrpt
What organelle are proteins synthesized with?
It is the ribosome. Proteins are synthesized on that
What is the function of a ribosome in a animal?
What is the function of a ribosome?
What is combined to form glucose in a special way?
chrolroplsdt from ribosome
What happens when ribosome parts pass into cytoplasm?
The ribosome subunits come together and form a functioning ribosome.
