Which explains why the nuclear membrane breaks down during cell division? 1. So the cytoplasm can be divided.
2. So the duplicated chromosomes can be separated into new cells.
3. so it makes it easier for the DNA to be mutated.
4. So the chromosomes can be replicated.

Sugar + oxygen > carbon  dioxide + water + energy  c6h1206 + 6o2 > 6co2 +6h2o + energy  and the numbers after the element symbols are small.     

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
