Genetics - SAGE QuestionWatch
I don't know what to do with this question! I've tried to do it but the approaches I tried don't get me any of these answers. The closest I got was 167,772,160 which is 10 x B so I may be on the right track but I can't get any of A-E.
Any help would be much appreciated!
In a SAGE (serial analysis of gene expression) experiment, 12 bp of sequence are used to identify cDNAs that have been prepared from RNA from the lung tissue of a mouse with cystic fibrosis. The mouse genome is 2,716,965,481 bp in length. If the GC content of the mouse genome is 50 %, what is the likelihood of detecting the sequence ACGTACGTACGT in the genome at random?
A. once every 20,736 bp
B. once every 16,777,216 bp
C. once every 226,413,990 bp
D. once every 2,716,965,481 bp
E. you will never find this sequence
- Thank you!
