Which of these illustrates the secondary structure of a protein?
In: Biology
An Hfr strain that is met + pro + bio + his + was mated with an F- strain that was met - pro - bio - his -. Mating was interrupted and the percentage of cells with each phenotype was determined by replica plating the cells on minimal media plates that lacked met, pro, bio or his. The data shown in Figure 1 were obtained. (Figure 1)
Using the data in Figure 1, label each line on the results graph below.
Drag the phenotype to the appropriate line on the graph.

Generally speaking, which of the following mutations would most severely affect the protein coded for by a gene?
In: Biology
Label the four mutated DNA segments shown below according to the type of point mutation each represents. Use the codon table above to determine how each mutation would affect the amino acid coding for each segment.
Drag the labels to their appropriate locations to identify the type of point mutation shown.

The diagram below shows an mRNA molecule that encodes a protein with 202 amino acids. The start and stop codons are highlighted, and a portion of the nucleotide sequence in the early part of the molecule is shown in detail. At position 35, a single base-pair substitution in the DNA has changed that would have been a uracil (U) in the mRNA to an adenine (A).
Based on the genetic code chart below, which of the following would be the result of this single base-pair substitution?
