p2 + 2pq + p2 = 1, where p represents the dominant allele and q represents the recessive allele. Because we know that p2 represents the frequency of the homozygous dominant genotype, we can find the frequency of the dominant allele (p) by taking the square root of the frequency of the genotype. The square root of 0.49 is 0.7. Note that by using the formula p + q = 1, we can also determine the frequency of the recessive allele (q). It would be 0.3 (0.7 + q = 1). 35. A Crossing-over (exchange of
and would therefore increase the length of the mRNA. (C), Exons are the coding sequences that are kept by the mRNA. (E), Translation is when we produce a protein from a molecule of mRNA. 96. E Make sure you read the question carefully. You are asked to calculate the number of liters per week, not per day. The chart tells us that a coconut palm loses 75 liters a day, which would mean 525 liters a week (7 × 75 = 525). 97. A Water moves from the soil to the leaves via tracheids. (B) and (D),

place while the RNAs assist in assembling polypeptides. Initiation Ribosomes contain three binding sites: an A site, a P site, and an E site. An initiator tRNA serves to activate translation and occupies the P site. In all organisms the codon for the initiation of protein synthesis is A–U–G, which codes for the amino acid methionine. The tRNA with the complementary anticodon, U–A–C, is methionine’s personal shuttle. Once the methionine tRNA is attached to the P site, the A site can be
