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 total cost of replacing everything: One more way to look at home maintenance is to figure the cost to replace everything in the home after its typical life cycle. For example your fridge might last 20 years and you'd have to replace it so the cost of maintaining a fridge annually is purchase price / 20.Using the cost estimator at Improvenet, I figured that a new roof will run $4000 to $9000 for a 1500 square foot house. The roof will last 20 years so thats $200 to $450 a year. brand new home should not cost anywhere near as much to maintain as a run down home built 100 years ago. So getting a generic number for home maintenance costs is not realistic. However when you're buying a home you should at least have some sort of ballpark idea of what maintenance costs will be.
