All of the different proteins in a cell are made from the same 20 amino acids. These amino acids are encoded by the genetic information in DNA and are linked together in specific sequences to form different proteins with unique structures and functions. The diversity of proteins in a cell arises from the different sequences and arrangements of these 20 amino acids.
What else can I help you with?
Two proteins in the same cell perform different functions. this is because the two proteins are composed of?
Different sequences of amino acids and possibly different numbers.
Do all cell membranes contain the same kind of proteins in the same relative locations?
No. Though all cell membranes have the same general characteristics outlined in any Biology textbook, they are all unique in type of proteins. Cell membranes between members of the same species will differ, and membranes within the same individual with differ also. The location of proteins will differ too, since they are subject to drifting and relocation. Some integral proteins will move slowly or not at all due to their connection to the cytoplasm, but others take advantage of the fluidity of the phospholipid bilayer.
How are proteins similar and different?
They are all made of the same basic units. The units are put together in different orders.
Do each cell in the human body has a different genome?
No. The genome is the entire DNA list on how an organism is to be made; it is a recipe and a set of instructions on how to make 'things' or components in the organism for it to live and survive. By following these instructions, the body can put together bits to make proteins. These bits are amino acids. Proteins once made, have a 'destiny' and go to their destined location to carry out their fated function. Cells are made of a bunch of different proteins. At the center of each cell is a control center known as the nucleus which contains these instructions for survival. So yes, it needs the same DNA in all cells. HOWEVER, the expression of the DNA is different in different cells with different functions and components. The DNA is set of instructions but it can be selectively picked apart for coding to produce certain types of proteins. And that is why bone cells differ greatly from muscle cells, though they still have the same DNA.
What is a ribosomes function in a prokaryotic cell?
The function is same as of eukaryotic cell i-e they make proteins for the cell
What molecules made of proteins?
Different combinations of the same 20 amino acids.

How the complex proteins are made?
Complex proteins are made the same way as regular proteins; through translation.
Are plants made of the same types of cells?
no they are made up of many different cell parts

If two proteins are in the same cell performing different functions it is because the two porteins arwe composed of what?
chains folded differently and a different sequence of amino acids

Something that performs same function as ribosome?
I believe it performs the same function as a cell.
Are all the proteins the same?
no they are all different
Why do different proteins have the same relative molecular mass?
Different proteins can have the same relative molecular mass because molecular weight alone does not determine a protein's structure or function. Proteins can vary in amino acid sequence, post-translational modifications, and three-dimensional structure while still having the same molecular mass. Thus, proteins with different compositions and functions can have similar molecular masses.
