DNA transcription is the reading of DNA by an RNA polymerase, usually RNA polymerase II in humans. The RNA polymerase then copies the DNA sequence into an RNA sequence, different examples of RNA, which all have different functions, are mRNA, tRNA, rRNA, snRNA, hnRNA.
This mRNA is actually what is read by the machinery which makes proteins, while tRNA is an accessory RNA which is used in conjunction with rRNA and ribosomal proteins to make the proteins.
In short, DNA transcription is making RNA from DNA.

Transcription is the process in which DNA is made into RNA so that it may be translated into proteins.
A good analogy is that DNA can be thought of as a master cookbook, RNA transcription is gathering and organizing all the ingredients you need to make the protein which is your final product.

Transcription is the process by which DNA is used as a template to create RNA.

there are three processes that DNA is involved in to make and keep the code for proteins: replication, transcription, and translation.
Transcription is when a segment of DNA is unzipped at its weak hydrogen bonds so that one strand with the nitrogenous bases is exposed. Then, mRNA (messenger RNA) is formed by connecting to these bases with corresponding bases (uracil to adenine, adenine to thymine, and cytosine to guanine, guanine to cytosine). The strand constructed is then unzipped from the DNA strand, the DNA rezips, and the mRNA is free to travel away from the nucleus to a ribosome, where proteins are made.
This is simply the transfer of information from DNA to mRNA to make a specific protein; the strand copied is a single gene.

Written/typed results of your DNA...genetic make-up.
