Answer:
A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).
Explanation:
Working with skeletal muscles, tendons, ligaments and joints, the bones form the moving machinery of human body. The major role of bones in movement is that they act as levers, which make use of the forces generated by skeletal muscles in a beneficial way.
