Which of the following statement is INCORRECT from the set of statements given below?

#Unit 2. Cellular Organization
  1. Since deamination is a common cause of DNA damage, and since the deamination of cytosine forms a product similar in structure to uracil, repair enzymes cannot repair this damage easily.

  2. In packaging the eukaryotic DNA into nucleosomes, it is thought that the requirement for histone proteins and their synthesis is a cause of the slower rate of movement of the replication fork.

  3. In photoreactivation, DNA damage caused by UV light is reversed by DNA photolyase which forms a complex with thymine dimers which absorbs visible light and reverses the dimerization.

  4. DNA is the only cell macromolecule that can be repaired.
