1) What are homopolymers use in discovering the genetic code? How were they
made and used? 2) How can you use heteropolymers with two precursur bases in specific ratios
to resolve the genetic code? 3) What considerations led scientists to hypothesize that the code was a triplet,
non-overlapping code? 4) Consider this gene. Show the m-RNA synthesized from the sense strand. 3'_________________________________5'.......
__________ 5)Consider the eukaryotic DNA sense strand below (in colors).
Construct the hn-RNA(initial m-RNA transcript) , m-RNA, and Polypeptide encoded
by this DNA. You will have access to a genetic code on an exam - use your book
or the web for this one. promoter 1st base transcribed Exons Intron terminator hn-RNA: m-RNA: Polypeptide:
