DNA,+RNA+and+Protein+Synthesis+Whiteboard+Questions

DNA vs. RNA

1. Draw a sketch of DNA and label its name and function. Draw a sketch of each of the three types of RNA and label their names and functions. 2. List the four nitrogen bases of DNA (full names!) and the four nitrogen bases of RNA (full names!). Draw lines to connect which DNA nucleotides would match to the RNA nucleotides. 3. Make a T-chart with DNA and RNA as the headings. List five features of DNA and RNA and compare them in your t-chart. For example, DNA is double-stranded, RNA is single-stranded. Keep going!

Protein Synthesis

1. Draw the central dogma of protein synthesis. For each arrow, indicate where in the cell each "arrow" occurs. 2. Draw the central dogma of protein synthesis again. For each arrow, label transcription, translation and protein modification. 3. Transcription - Draw a strand of DNA with a bubble in the middle. Using a different colored marker, draw a piece of mRNA forming that would match the DNA sequence. Label at least 6 nucleotide bases from DNA that correspond to the RNA. 4. Translation - Draw a strand of mRNA and a ribosome attached (hamburger). Show two tRNA molecules docking to mRNA in the ribosome and delivering amino acids. 5. If DNA reads TACGGC, what does mRNA read? If DNA reads GGGCCC, what does mRNA read? If DNA reads GTCCTA, what does mRNA read? 6. Translate each of the above mRNA codes that you wrote into amino acids.
