Kinds of DNA damage and lesions (spontaneous and induced) produced by specific exposures. (Note: don't forget transposons and CRISPR Cas9) Specific repair mechanisms that fix each kind of DNA damage or lesion (during/post replication). • Include information about the number of replication cycles for a dominant mutation to cause a phenotype. And the number of cycles for a recessive mutation to possibly cause a phenotype. (Hint: don't forget to think about each strand of both parental copies of each chromosome) OExamine the DNA model, what are the features that contribute to the stability and the ability of the DNA to replicate faithfully?
