I know that the chromosomes contain the genetic materials and the 
different sequences and numbers of organic base in chromosomes determine 
what proteins produced.
As chromosomes only give instructions to produce what kind of protein .Why 
the extra chromosome in Down's syndrome people resulted low IQ and shorter 
The extra one do nothing but produce RNA for synthesis only.So i want to 
know details are this.
If i have something wrong .Please correct it for me.
