Primary transcript

... the polypeptide, this is because? A. substitutions are corrected before transcription begins B. substitutions are restricted to introns C. the base-pairing ... in RNA splicing D. RNA splicing can be catalyzed by spliceosomes E. A primary transcript is often much longer than the final RNA molecule ...

My question is in regards to DNA transcription. Please read below: The RNA polymerase recognises the promoter region ... adding nucleotides into the growing RNA molecule. This molecule is then called a primary transcript. It is modified into a mRNA by enzymes that cut out the intron regions ...

almost mRNA sequences in GenBank canot be represent full-length transcripts. and the full-length transcripts are, on average, 45 bp longer ... suggest to skip it. It is more important to know differences between primary transcript and mRNA.That's all. And if u mean on genetic libraries ...

mRNA not of exon but exones and primary transcript not of exon and introne but exones and intrones like this gene exone1-introne1-exone2-introne2 ...

First during transcription complementary RNA is formed(full length transcipt or primary transcript) -it consists of egzones+intrones so whole gene is trancribed. Then by special mechanism ...
