Suppose the coding (sense) strand of some DNA has this base sequence: 5-GATGTATA-3' Write the base sequence of the mRNA that would result from transcription of this DNA.

Enter the corresponding section of mRNA produced feom the following sections of a DNA template strand:   G C G A A T G A C C A T

Suppose that codons consisted of 4 nucleotides instead of 3 and that there were only 2 different bases. How many amino acids could be encoded by this variant of the genetic code?

Given the following coding strand of DNA: 3' – TACCGAGTACTGACT – 5', the MRNA that will transcribed from this gene is 5' fill in blank 3'.

How many amino acids are coded for by the following mRNA: 5 '-Cap-GCCCACAUGCAAUUUUGCUCACCAUAACAAAAAAAA- 3' O 7 6 8 12 9.

Give the sequence of the LEFT (5'-end) region of this RNA strand that would participate in forming the stem of a stem-loop with this bit of RNA. DRAW this stem-loop in your scratch work!     5’-UGGUGGAUCUCUGCAACUGAUCCAUUG-3’

The eukaryotic mature mRNA sequence will be translated into a polypeptide that is _____ amino acids long (hint remember to "be a ribosome" and scan for the AUG and look out for stop codons!).   5’-CCATTCAUGUUUGGUGGCUAACCA-3’
