1) Consider the following partial single-stranded DNA sequence:

T A C G G T A C A G C C T C G

(a) If the above DNA sequence is transcribed and translated, what would the mRNA and amino acid sequences be?

mRNA:

Amino Acids:

(b) Suppose that nucleotides #4-5 and #13-14 were spliced out of the above mRNA sequence. In the space below, write the mRNA sequence that would remain after this splicing occurred:

(c) What amino acid sequence would a cell produce using the sequence you wrote in part b?  

(d) Go back to the original mRNA sequence you wrote in part a.  Now suppose that nucleotides #7-9 were spliced out of this molecule.  In the space below, write the mRNA sequence that would remain after this splicing occurred:

(e) What amino acid sequence would a cell producing using the sequence you wrote in part d?

(f) Is it possible the same gene to produce more than one type of protein?  Explain your answer.
