mRNA is created during transcription. During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides ...

RNA vaccines train the immune system in a similar way to traditional vaccines, but they use a different strategy to get there ...

Leftover drops in vials of Moderna’s COVID-19 vaccine allowed a group of researchers from Stanford University to determine the sequence of the mRNA for SARS-CoV-2’s spike protein that is used in the ...

are clipped out of the mRNA strand. This process "tidies up" the molecule and removes nucleotides that are not involved in protein production (Figure 6). Then, a sequence of adenine nucleotides ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed ... by complementary base pairing to form a strand of mRNA: Note - RNA nucleotides contain the same bases as ...
