During the first stage of protein synthesis, which is known as transcription, the correct process is:
**The DNA unzips, and RNA bases match up along a strand.**
In this stage, the DNA double helix unwinds and unzips to expose a specific gene. RNA polymerase then synthesizes a single-stranded messenger RNA (mRNA) molecule by matching RNA bases (adenine with uracil, and cytosine with guanine) to the DNA template strand. Once the mRNA strand is synthesized, it will eventually leave the nucleus and move to the ribosome for translation, which is the next stage of protein synthesis.
