Central Dogma
Process of how DNA goes to and how RNA goes to Proteins
DNA -> RNA = Transcription
In RNA, instead of A pairing with T, A pairs with U
Bases of the DNA are transcribed into RNA format
RNA -> Proteins = Tranlsation
tRNA creates anticodons, while mRNA makes codons. These Codons pair with Anticodons and code for proteins. They are put through the a protein synthesis machine inside the cells which produce proteins
