Answers

The correct answer is S phase.

The critical phase of cell cycle is S phase, in this phase the DNA starts replicating.The cell cycle is called the synthesis phase because the synthesis of DNA starts in this phase. There is no chance that the cell can go back to the previous phase. The DNA within the cell starts replicating. Depending upon the level of nutrients, energy and external factors, cells must decide that they will enter into cell cycle or not.

The amino acid in figure one is found in a region of a polypeptide that folds away from water which part of the amino acid and most likely contributes to the hydrophobic behavior of this region of the polypeptide

Answers

Answer:What part of the amino acid contributes to the hydrophobic behavior of a region of the polypeptide?":

The hydrophobic behavior of a region of the polypeptide is primarily influenced by the presence of nonpolar amino acids with bulky side chains, such as alanine, valine, leucine, isoleucine, phenylalanine, and tryptophan. These nonpolar side chains do not interact with water molecules and instead fold away from water to minimize contact with the polar environment.
