To convert DNA to mRNA, a process called transcription occurs. During transcription, an enzyme called RNA polymerase reads the DNA sequence and creates a complementary mRNA strand by matching the nucleotides. This mRNA strand carries the genetic information from the DNA and can then be used by the cell to make proteins through a process called translation.
DNA to mRNA is transcription, whereas mRNA to tRNA is translation. The latter part is when proteins are made from ribosomes and instructions carried over by mRNA from the DNA.
Instructions from DNA are carried to ribosomes by molecules of amino acids. These are carried by tRNA while mRNA carries information from the genes to ribosomes.
To find the mRNA sequence, one can use a technique called reverse transcription polymerase chain reaction (RT-PCR) to convert the RNA into DNA, which can then be sequenced using methods such as Sanger sequencing or next-generation sequencing.
A strand of DNA
The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.
The mRNA comes into the DNA when the DNA unzips. Then the mRNA attaches to one side of the DNA, copies it down, and leaves. Remember, AT CG
DNA to mRNA is transcription, whereas mRNA to tRNA is translation. The latter part is when proteins are made from ribosomes and instructions carried over by mRNA from the DNA.
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.

To my knowledge there is no such thing as a DNA translation enzyme. DNA is not translated; it is transcribed. During transcription, RNA polymerases create mRNA molecules by reading off from the sequence of the DNA template strand. Then the mRNA molecule is translated by ribosomes that convert that use each successive codon of the mRNA sequence to code for a particular amino acid. This last process - the use of sequence information in mRNA to direct the synthesis of a polypeptide chain - that is translation and it does not involve DNA.
Mutations not only change the DNA, but a change to the DNA will change the mRNA. This explains why a mutation in one generation can be passed on to the next generation.
