The shape of the molecule will determine the direction of each of the individual bond dipoles, and thus, will always play a role in determining the polarity of the molecule as a whole.
Think of each polar bond in a molecule as a little arrow pointing from positive to negative. This tells us that the bond dipole is a vector quantity.
Like any other vector quantity, the direction is a vital aspect of its description. So, the geometry of the molecule determines the direction that the bond dipole vectors point.
The polarity of the molecule results from adding up all these individual bond dipoles.
Answer:
False. There are 20 amino acids, but 64 possible codons.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
• The end codons are UAA, UAG, UGA.
