If the mass of an object increases, the force acting on it, such as gravitational force, also increases.
true or false ?

True. Mass refers to how much matter an object contains. Gravity refers to the attractive pull between two objects that have mass. Gravitational force is directly proportionate to the mass of an object. Therefore if there is an increase in the mass of an object there is also an increase in gravitational pull. To put it simply, the larger the objects, the greater the gravitational pull. A good example is between the size of the Earth and the moon. Earth is larger in size therefore the gravitational pull you experience here on Earth is greater than the moon's because the moon is much smaller in size compared to the Earth’s surface. 

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
