New research shows how technology and experimental methods in science can always help and be of help when trying to find out the fine details and see how a theory should be updated and what is needed to be corrected in a certain hypothesis or theory.
Dinosaurs they are termed as a diverse group of reptiles. They first appeared in the time of triassic.
After triassic and jurassic extinction event, dinosaurs became terrestrial vertebrates.
Answer:
The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.
The two post-transcriptional modifications are the addition of 7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.
The advantages of capping are:
1. Protection of nascent mRNA from the degradation.
2. Recognition by transcription factors helps in translation.
The advantages of tailing are:
1. Protection of the mRNA from enzymatic degradation in the cytosol.
2. Transcription termination
3. Export of the mRNA from the nucleus
