Lysenko planted 50 seeds in \( 100 \mathrm{~m}^{2} \) the first season, 50 seeds in \( 50 \mathrm{~m}^{2} \) the second season, 50 seeds in \( 25 \mathrm{~m}^{2} \) the third season, and continued this pattern forever. How many square meters did Lysenko plant altogether (Lysenko was a real person, a head of agriculture in the former Soviet Union, whose foolish and untested ideas of close crop spacing produced famines and starved millions).

Look at the genetic code below (or use the one in your textbook) to help you answer the questions. The genetic code is written for mRNA. In the space below, answer the following questions: A) If the original mRNA codon is AAC, what is a different codon that codes for the same amino acid? B) If the mRNA codon is AAC, what would be the anticodon found on the tRNA?
