g You generate a point mutation in the coding region of one specific gene and find that cells only expressing this mutant gene produce a much shorter (and non-functional) version of the translated protein. A. List and briefly describe one type of point mutation that could lead to this outcome. (2 points) B. Explain how the point mutation described in part A can substantially decrease the size and prevent the function of the resulting protein.

Asea turtle has washed up on a remote section of a beach. this known as a stranding occurs when a dead,sick or injured sea turtle washed up on the shoreline. which statment best explain why stranding should be reported immediately to local authorities

Natural selection changes allele frequencies because some survive and reproduce more successfully than others.

During crossing-over, a. genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles. b. nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. c. one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations of alleles. d. sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. e. genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
