In the picture below, a dog stands on a float in a pool about to jump
onto the pool deck. How could Newton's 3rd Law cause a problem?
a. The dog will have a lot of acceleration as he jumps away from the float.
b. When the dog jumps off the float to the left he is pushing the float to the right and
he might fall in the water.
c. The dog was at rest so he wants to stay at rest. It is going to be more difficult to get
moving
O
d. There is no problem. When he tries to jump off, he will jump forward.

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
