Genome Project Factoids

[Ed DesJardins]

Does anyone know the (approximate) answers to the following questions?  I
was asked these questions and wasn't quite sure if I was in the right ball
park.


1) What percentage of the human genome is protein coding information?  5%? 
Less than 5%?  Do these estimates include or exclude introns in the
calculation of "coding regions?"


2) What percentage of the human genome has been sequenced?  1%?  A few
percent?  Is the vast majority of the known human sequence information from
protein coding regions?


3) What percentage of the 100,000 or so genes that make up a human have
been cloned (sequenced) at the cDNA level (excluding ESTs)?  5%? 10%?


4) Of the 100,000 or so expressed human genes, how many have been
identified by EST?  50%  More than 50%?


Thanks.  Ed
