DNA polymerase III adds nucleotides to both ends of the RNA primer to the 5' end of the RNA primer to the 3' end of the RNA primer in the place of the primer RNA after it is removed to internal sites in the DNA template
1. Create a DNA sequence with eighteen nucleotides. Indicate its 3’ on the left and 5’ on the right since that’s the template strand you will need in the next question to transcribe the mRNA. 2. Transcribe the DNA sequence above and separate the triplets into codons. Indicate 5’ and 3’ in the correct location on the strand. (Don’t worry about splicing- assume that the pre- mRNA is the same as the mature mRNA sequence) 3. Look at the genetic code, and indicate which amino acid is coded for by the codons in the above mRNA. 4. ANSWER BELOW QUESTIONS: A. First write the original DNA strand. Indicate where the substitution was by either circling it or writing it in a different color. Then write the mutated DNA sequence with the point mutation (aka substitution) wherever you choose for it to be. Again, circle it or write it in a different color. Do the same for the transcribed mRNA. Repeat the directions for 2 and 3 for this new DNA stand. (i.e., include the mRNA and translated protein…

10. Why does a cDNA copy of a eukaryotic mRNA gene need to be made in order to determine the expressed protein sequence? Group of answer choices Genomic DNA is methylated and cannot be used as a template Genomic DNA is less stable than cDNA and is therefore harder to work with The genomic DNA sequence in eukaryotes contains introns which need to be removed first Genomic DNA is too long so the shorter mRNA copy is used The 5’ cap gets in the way of protein sequencing
