Which are the special proteins in muscles that contract and relax to cause movement?

 

In DNA, the chemicals are Adenine, thymine, guanine and cytosine. They always pair as basepairs like Adenine with Thymine and Guanine with Cytosine.

Protein synthesis take place in the cytoplasm where ribosomes are located as they are the machinery which are responsible for the protein synthesis.

RNA acts as a messenger in between the DNA and ribosome as it transforms the genetic information from the DNA and as DNA is big and can't fit into the nuclear pores. 

Most cellular activities will occur in the cytoplasm of the cell. Many metabolic pathways including glycolysis and process such as cell division occurs in the cytoplasm of the cell.
