You can't say it developed just one branch of science.
To name a few: Genomics, Genetics, Chemistry and The science of studying DNA itself. We can't forget about the uses in technology like DNA Nanotechnology.
But technically, the main branch of science developed after the discoveries about DNA was Molecular Biology.
first step in protein production is the transcription of DNA to mRNA in the nucleus. the next organelles involved are ribosomes. if the protein is not destined to the cell membrane the mRNA is translated on a cytoplasmic free-floating ribosome
I believe your answer would be the stem.
