What prevents the wrong nucleotide from being added to the new strand during dna replication?

It prevents the separation DNA strands from reattaching to one another during DNA replication is called DNA Helecase. 2 major enzymes used during DNA replication is DNA helicases, DNA polymerase. DNA Helicase is an enzyme that unwinds the DNA double helix during DNA replication.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

well, i believe that the answer is 2. : 3
