How does the role of RNA polymerase in transcription differ from that of DNA replication? polymerase is an enzyme that catalyzes the conversion of free nucleotides into a single strand. DNA polymerase differs from RNA polymerase in two major respects: Like all â¦enzymes, DNA polymerase is substrate-specific.
Home maintenance: On average, homeowners will spend between 1 to 4 percent of a homeâs value annually on maintenance and repairs, which tend to increase as the house ages. U.S. News and World Report Note: for a $200,000 home, thatâs at least $2,000 in repairs annually.
The percentage estimation method will tell us that the well maintained house should have an annual maintenance budget of $4,000 (2% of $200,000), but the run-down house only needs $3,000 per year (2% of $150,000). This is clearly incorrect, since itâs very likely that the cheaper house will need more maintenance.s a home owner, Iâve seen various methods of estimating annual home maintenance costs. These methods involve calculating a percentage of your home value â usually between one to four per cent, and using that value as the annual maintenance estimate.
