Imagine that a researcher has found an unusual cell that seems to be unable to replicate its dna. the problem is most likely linked to which phase of the cell cycle?

The problem is most likely linked to the S phase of inter phase of the cell cycle when DNA is replicated, the DNA stays during the G2 phase. The S phase or the synthesis phase of the cell cycle when the DNA packaged into chromosomes is replicated. This event is an important stage of the cell cycle because replication allow for each cell created by the cell division to have the similar genetic makeup. All through S phase a number of events added to chromosomes replication take place. Cell growth endures through the S phase as does the amount of synthesis of a number of proteins and enzymes that are elaborate in DNA synthesis. Once done the cell comprises twice its normal number of chromosomes and becomes prepared to pass in the phase called G2 

Six amino acids have side chains that are polar but not charged. these are serine (ser), threonine (thr), cysteine (cys), asparagine (asn), glutamine (gln), and tyrosine (tyr). these amino acids are usually found at the surface of proteins, as discussed in the proteins 2 module.
