Central Dogma: DNA base pairing

With all of the HHS science teaching staff participating in a Studio Day, students were tasked with completing a DNA base pairing worksheet with guidance from a substitute teacher.   Students learned that in complementary DNA strands, A pairs with T and C pairs with G.  When RNA is transcribed from DNA, the rules are the same with one exception: mRNA uses U instead of T, so in a DNA:RNA pairing, the A in DNA pairs with U in RNA.  Students went on to learn about codons (adjacent sets of 3 RNA bases) and learned how codons code for amino acids.  Students learned how to write the 3-letter and 1-letter amino acid abbreviations, and solved the amino acid structure from a DNA strand, as well as solved a DNA strand from a short amino acid sequence.
