Homework #2 (20pts) BIOL301 Stansbury Name written below is ashortstretch ofnucleotides from one strand of a double-stranded molecule of bacterial DNA (the complementary sequence is not shown, but implied). s TccTGCATTCA TGATCGCGACcTCCTTACTAAACATTTGATTAT CGcGAACCCAGAATAAccCTGTCAACGG a) Determine approximately where transcription would begin in the presence of bacterial RNA polymerase and drawthe molecular structure of the first three nucleotides of the resulting mRNA strand (nitrogenous bases represented with a box) may be What are the first five amino a that would be translated from the mRNA strand?

Explanation / Answer

Transcription start site is the 5'end of the gene. The binding of the RNA polymerase to the promoter sequence will initiate transcription. The promoter is generally located at the 5' site.

The translation sequence and the amino acid sequence is

The first 5 aminoacids include- Met-Ile-Ala-Thr-Ser
