A sample of double-stranded DNA contains 40% cytosine. Approximately what percent of the nucleotides in this sample will be thymine?   

What is the primary function of helicase in DNA replication?   

Which of the following investigators was (were) responsible for determining that DNA contains equal amounts of adenine and thymine, and equal amounts of guanine and cytosine?   

Which enzyme catalyzes the elongation of a new DNA strand in the 5′ → 3′ direction   

Which enzyme catalyzes the elongation of a new DNA strand in the 5′ → 3′ direction   

  Use the figure and the following description to answer the question. In a particular plant, leaf color is controlled by gene locus D. Plants with at least one allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A true-breeding, dark-leaved plant is crossed with a light-leaved one, and the F1 offspring is allowed to self-pollinate. The predicted outcome of the F1 cross is diagrammed in the Punnett square shown in the figure, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square.      Which of the boxes marked 1-4 correspond to plants that will be true-breeding?   

Which of the following statements correctly describes the relationship between genotype and phenotype?   

How many unique gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE?   

Which of the following statements correctly describes the relationship between genotype and phenotype?
