Which of the process makes copy of a dna moleclue

I hope it helps;

Explanation:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

DNA copies itself before cell division so that each new cell has the full amount of DNA. What is method by which DNA replicate? the enzyme DNA helicase breaks the hydrogen bonds between bases on the two polynucleotide DNA strands.

Thanks

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
