The answer to this question would be: 14 days.
The skin is consist of keratinized cells that will keep multiplying. The cells start at the stratum basale and will keep moving up changing the old ones until it ends up at the outermost layer of stratum corneum.This process will take time around 2 - 4 weeks.
Mistakes not corrected during DNA Replication
Universal genetic code
Transcription and Translation
All amino acids after a Frameshift mutation are changed
They can either change one base or delete or add another
Ionizing radiation can induce mutations
Of course sometimes mutations don't change the amino acid sequence
Noncoding DNA Strand is complimentary to RNA
Because of pollution and over fishing.<span />
It inhibits the ligation activity.
Antimicrobial agents interfere with either DNA replication cell wall synthesis, plasma membrane integrity, ribosomal function, or folate synthesis. Ciprofloxacin belongs to fluoroquinolones class of antibiotics that interfere with DNA replication. DNA gyrase is a bacterial topoisomerase that cuts and then reseals DNA to change DNA topology during replication. The binding of ciprofloxacin to A subunit of gyrase enzyme stabilizing gyrase–DNA complex. This leads to inhibition the resealing (ligation) activity of the enzyme leaving the DNA fragmented.
