Answer: DNA provides a set of chemical instructions to specific genes that the gene uses to make proteins in order to determine traits.
Explanation: Genes provide instructions that are used to determine the sequence of amino acids needed to make up a protein.

The oceans, lower atmosphere, and continents are parts of the biosphere.
The biosphere is composed of the parts of planet Earth where life exists and it is the total of all the ecosystems. The biosphere along with lithosphere (rock), hydrosphere (water) and atmosphere (air) are the four layers that surround the earth. The biosphere covers a wide area from the deepest root systems of trees, to rainforest, to the ocean depth and high mountaintops. The biosphere contains living organisms and nonliving things from which they obtain energy and nutrients.
I found the whole exercise on the internet. Here are the events mentioned:
"-<span>Mismatched bases in the heteroduplex trigger mismatch repair.
-Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
-A heteroduplex is formed between </span>R (wild-type) and r (mutant) alleles.
-Mismatched bases are excised from the R (wild-type) allele.
-The wild-type R allele is converted to the mutant r allele."
The correct order is:
1. Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
2. A heteroduplex is formed between R (wild-type) and r (mutant) alleles.
3. Mismatched bases in the heteroduplex trigger mismatch repair.
4. Mismatched bases are excised from the R (wild-type) allele.
5. The wild-type R allele is converted to the mutant r allele.
