Where proteins are made?
Proteins are made from amino-acids and are assembled Via Ribosomes. RER [rough endoplasmic reticulum] contains Ribosomes while SER [smooth endoplasmic reticulum] does not.They are synthesized by ribosomes which are found in the cytoplasm of a cell.
Can ribosomes be present in eukaryotes?
Eukaryotes do have ribosomes. In fact, they have 2 types of ribosomes: those which synthesise internal proteins and those which synthesise external proteins.Internal proteins (to be used within the cell) are made at ribosomes which float freely in the cytoplasm of the cell. External proteins (to be used outside of the cell, in other cells or in the cell membrane) are made at ribosomes which are bound to the outer membrane of the rough endoplasmic reticulum (rER).Eukaryotes do have ribosomes.

What bio molecules are in a ribosomes?
Ribosomes translate mRNA to proteins. In eukaryotic cells, the ribosomes attached to the rough endoplasmic reticulum (RER) produce proteins that are either to become part of organelles (such as lysosomes), the plasma membrane, or secreted from the cell. The free, or soluble, ribosomes found in the cytosol produce proteins that remain in the cytosol, e.g., the enzymes involved in glycolysis.
Which organelle makes proteins using coded instructions contained in the organisms DNA?
Some ribosomes can be found floating free in the cytoplasm, while others are bound to the rough endoplasmic reticulum. (The name "rough" actually indicates the presence of ribosomes, against the "smooth" appearance of the smooth endoplasmic reticulum, which lacks ribosomes). There are several types of ribosomes,(rRNA = ribosomal RNA, mRNA = messenger RNA, tRNA = transfer RNA), all of which has its distinct job in the synthesizing process of protein. Information of regarding this process can be found on http://en.wikipedia.org/wiki/Protein_synthesis Ribosomes are considered "non-membranous organelles", as they differ from other organelles which are membrane-bound.
Are carrier proteins are located in the membrane?
yes they are

What do ribosomes synthesize?
Ribosomes synthesize proteins. They are found outside of the cell's nucleus, and they create proteins from amino acids.
Where are membrane proteins are found?
Surprisingly, membrane proteins are found in or attached to the membrane.
what are ribosomes?
A ribosome is a cell organelle. It functions as a micro-machine for making proteins. Ribosomes are composed of special proteins and nucleic acids. Ribosomes are found ‘free’ in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes.Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome. Ribosomes have only a temporary existence. When they have synthesized a polypeptide, the two sub-units separate and are either re-used or broken up. Ribosomes are bound by a membrane.
What is attached to membrane systems and scattered in the cytoplasm and synthesize proteins?
Ribosomes. They are the actual site of protein synthesis and float free or are attached to a membranous structure (rough ER) in the cytoplasm.
What small structures are found attached to the rough endoplasmic reticulum?
what sometimes found attached to the endoplasmic reticulum ? and give me the full defenition
Ribosomes use the directions found in DNA to make-?
proteins
Protein Synthesis occurs in structures attached to the?
Proteins are synthesized in the ribosomes which are found in the cytoplasm. They are manufactured through translation and transcription processes in the cell.
Can you use ribosomes in a short sentence?
Ribosomes is where proteins are found in a cell
What are found on the ER and manufacture proteins?
Ribosomes are the structures found on the ER that manufacture proteins.
Where are components of ribosomes synthesized assembled and found in the nucleus?
Golgi Apparatus
