Individuals with the disorder xeroderma pigmentosum are hypersensitive to sunlight, and mutations to the dna in their skin cells are left uncorrected. why are the mutations not corrected in individuals with this disorder?

This disease is caused by mutations in 8 genes involved in DNA repair. Seven of these genes are involved in nucleotide excision repair. Some of the genes involved code for DNA polymerase, which is necessary for DNA replication with UV-induced damage.

The wavelength of ultraviolet light, which oscillates between 280 and 340 nm, induces a DNA or nucleotide lesion, under normal conditions the cells have the capacity to repair this damage, in people with this disease there is a defect in excision. Nucleotide repair by an alteration in the enzyme that is responsible for the repair of nuclear DNA in the course of mitosis.

i think that it is c, d, and e, hope this

the  different  of  these  two  are  that  they  differently  handle  their  team.

an  expressive  leader  focuses  on  the  task  at  hand  and  make  sures  that  their  goal  is  achieved.  they  accurately  finish  the  task.  an  instrumental  leader  on  the  other  hand  works  on  the  unity  of  the  group,  they  care  more  about  their  employees.  all  the  while  creating  a  good  environment.
