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 ...

Infer type of nucleic acid based on number of nucleosides

Lets say we analysed a nucleic acid and found out that it had 20% Adenosine, 25% Guanosine, 40% Thymine and 15% Cytosine. We know that A always pairs with T and G with C. So, based on these numbers, ...

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 ...

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?
