Why and how is DNA synthesis so much faster then RNA synthesis?

DNA synthesis in E. coli is 20x faster than RNA synthesis at 1000nt/s vs 50nt/s. (Mirkin'05) I find that perplexing since DNA polymerization has better proofreading than the RNA variety, which ...

What are the reasons which make intron detection uncertain?

Intron/exon sequence detection seems to involve statistical prediction which can at best deliver a guess (until experimentally confirmed) as to where the splice site is. What are the reasons why ...

Will bacterial promoter without either -10 or -35 sequence allow no transcription?

I have a strong constitutive promoter on a plasmid inside of E.Coli, which expresses a gene. Having either -10 or -35 sequence modified to random sequence, will it ensure zero transcription from that ...

DNA replication: in which direction does the DNA polymerase 3 work?

In a couple of sites I have seen, it states that it reads in 3' to 5' direction (upstream) though the daughter strand is made in the 5'-3' direction. How does that work?
