Genetics homework 3
ethylmethane sulfonate
alkylating agent
order the steps of the methyl-directed mismatch repair system
1. parental strands are marked with methyl groups 2. MutS and MutL recognize mismatch in replicated DNA 3. MutL recruits MutH, which makes a nick opposite the methyl tag 4. DNA exonucleases remove DNA from the new strand 5. the new strand is repaired and methylated
5-Bromo-uracil
base analog
nitrous acid
