do they oppose each other?

They go together. Evolution is a consequence of random mutations in the DNA of an individual. These mutations happen because of copying errors when a cell splits or as changes induced by radiation or chemicals.
Most mutations are without consequence. But these mutations happen a lot. And as DNA codes for proteins which direct chemical reactions in the body, it can and will happen that a mutation does have positive consequences for the individual.
Evolution takes place because in nature the individuals that have the best changes of survival have -on average- more offspring.
And these children will inherit the same mutation that favoured the parent in the first place.
It's a slow process. But life on earth had hundreds of millions of years to do it.

No. DNA (Deoxyribonucleic acid) is a result of evolution. Billions of years ago when the earth was just barren, just earth (rock, both molten and solid) and water. With an atmosphere filled with many noxious chemicals, such as methane, ammonia, water, hydrogen sulfide, carbon dioxide, and phosphate. With time, pressure and heat these basic chemicals would form all sorts of other chemicals including amino acids. Amino acids are what make up proteins and are essential for life because they store energy and assist with many different chemical reactions needed for life. DNA is a pair of RNA molocules, both of which are a series of nucleic acids, which direct the formation of proteins.
Evolution describes how life changes over time and spins off a new form of life. It shows how mutations in life occur for the survival of a species. Like the slight differences between a sparrow. One might have a slightly more pointy and hard beak which could be good for getting sees, whereas another one might have a slighyly wider and softer beak which could be good for chomping bugs. These chages are an adaption to its environment, because a seed bird isn't going to survive as long if there's little or no seeds to be had.

The process of evolution acts on an E. coli cell by creating a mutation in the DNA. It is not uncommon for the DNA strand in an E. coli bacterium to get corrupted. An X-ray, a cosmic ray or a stray chemical reaction can change or damage the DNA strand. In most cases, a particular E. coli cell with mutated DNA will either die, fix the damage in the strand or fail to reproduce. In other words, most mutations go nowhere. But every so often, a mutation will actually survive and the cell will reproduce.

This is the concept of DNA:
Since the beginning of human history, people have wondered how traits are inherited from one generation to the next. Although children often look more like one parent than the other, most offspring seem to be a blend of the characteristics of both parents. Centuries of breeding of dpomestic plants and animals had shown that useful traits - speed in horses, strength in oxen, and larger fruits in crops - can be accentuated by controlling mating. However, there was no scientific way to predict the outcome of a cross between two particular parents. It wasn't until 1865 that an Augustinian monk named Gregor Mendel found that individual traits are determined by discrete "factors", later known as genes, which are inherited from parents. His rigorous approach transformed agricultural breeding from an art to a science. He started with parents of known genitic background - to provide a baseline against which to compare patterns of inheritance in the resulting offspring. Then he carefully counted the numbers of individuals showing the various traits in successive generation of offspring.
From what I know:
Evolution happens because of mistakes in the transfer of genes from parent to offspring. The results will then vary the structure and appearance of the offspring.
Thus, both complement each other.

Evolution is the process and DNA is the mechanism by which it is achieved.

The creation thing in the bible and DNA contradict each other.
