Slide 11 problem:

   5’ UGG 3’-  mRNA

                      -TemplateDNA stand

  -Nontemplate DNAstrand

Slide 33 problem:

The following sequence of nucleotidesin a DNA strand was used as a template to synthesize a mRNA thatwas then translated into protein:

                        5’-TTAACGGCTTTTTTCCAT-3’

Predict the C-term aa and the N-termaa of the resulting polypeptide.

Slide 34 problem:

True or False? Explain youranswer!

1.An individual ribosome can make onlyone type of protein.

2.The large and small subunits of anindividual ribosome

always stay together and neverexchange partners.

3.An mRNA may contain the sequenceATTGACCCCGGTCAA

Slide 35 problem:

A mutation in DNA generates a UGA stopcodon in the middle of the mRNA coding for protein X. You arestudying protein X and isolating it from mutated cells. Which onebest describes your findings:

1. No changes whatsoever are found between protein X isolated fromwild type and mutant cells
2. Protein X from wild type cells is shorter than the one frommutant cells
3. Protein X from wild type cells is longer than the one frommutant cells
4. Protein X from mutant cells has a new function
