Ribosomes are composed of special proteins and nucleic acids. A eukaryotic ribosome is composed of nucleic acids and about 80 proteins. About two-thirds of this mass is composed of ribosomal RNA and one third of about 50+ different ribosomal proteins.
yes
It is the ribosome. Proteins are synthesized on that
What is the function of a ribosome?
chrolroplsdt from ribosome
The ribosome subunits come together and form a functioning ribosome.
Prokaryotic and eukaryotic
A free ribosome is a ribosome that is not attached to the rough endoplasmic reticulum and is thus suspended in the cytoplasm.
Ribosome is singular, the plural form is ribosomes
DNA tells a ribosome how to assemble a protein.
The ribosome is signaled to begin making a polypeptide by the start codon (AUG) present in the messenger RNA (mRNA) sequence. This start codon specifically codes for the amino acid methionine, which marks the initiation point for protein synthesis.
Ribosome assembly begins in the nucleolus of a cell.
The ribosome is a small organelle which can be a "free" ribsome or an "attached" ribosome. The ribosome makes protein that is nessacary for the cell to carry out their processes. If a ribosome is free, then it floats around in a gelatin-like substance called cytoplasm in the cell. If a ribosome is attached, then it is located on the endoplasmic reticulum (ER). If their is a ribosome attached to it, then it is considered the rough endoplasmic reticululm (RER). If their is no ribosome, then it is the smooth endoplasmic reticulum (SER).
