______________________________ __ _______________________________ Your name Your TA's name BioGD2810 Genetics Fall 2010 Quiz #9 The human gene for ß2 lens crystallin has the components listed below. The numbers represent nucleotide pairs. Assume for simplicity that no alternative splicing is involved. 5' UTR 174 1 st exon 119 1 st intron 532 2 nd exon 337 2 nd intron 1431 3 rd exon 208 3 rd intron 380 4 th exon 444 4 th intron 99 5 th exon 546 3' UTR 715 (a) (10 points; 1 point each) Answer the following questions about the ß2 lens crystallin gene, primary transcript, and gene product. Questions asking "where" should be answered with one of the 11 components from the list or with "None". Assume poly(A) tails contain 150 A's. How large is the ß2 lens crystallin gene in bp (base pairs)? 4096 How large is the primary transcript for ß2 lens crystallin in bases? 4246 (4247 if cap counted) How large is the mature mRNA for ß2 lens crystallin in bases? 1804
