Answer:
yes, gold can be created from other elements. The process requires nuclear reactions and is so expensive that currently it would cost a lot more than the price of natural gold available, therefore, unprofitable. Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, gold can be created by simply assembling 79 protons, (and enough neutrons to make the nucleus stable).
The answer is False

Answer:
True
Explanation:
A DNA molecule is composed of the nitrogenous bases stacked inside the two backbones made up of the phosphate and sugar molecules. The nitrogenous bases form the nucleotide which when read in the triplets called codons code for specific amino acid and then form proteins.
If we say that we have to protect the DNA than it means that we have to conserve the DNA molecule. Conserving the DNA molecule means that the sequence of nucleotide which codes for specific proteins must be conserved as it is the protein molecule that is essential for survival.
Thus, true is correct.
