What is the second step of DNA replication? O Free Noating nucleotides attach to their complimentary base pair
O DNA polymerase unzips the DNA
O DNA helicase zips the DNA molecule back up
O DNA is replicated

The basic building blocks of dna and rna are nucleotides

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
