Agenetic mutation resulted in a change in the sequence of amino acids of a protein, but the function of the protein was not changed. which statement best describes the genetic mutation? a.) it was a silent mutation in a coding region of dna that caused a change in the dna of the organism. b.) it was a nonsense mutation in a non-coding region of dna that caused a change in the dna of the organism. c.) it was a nonsense mutation in a non-coding region of dna that caused a change in the phenotype of the organism.

Use this dichotomous key for insect identification to identify the insect shown. 1. a. insect has one pair of wings. order diptera b. insect has two pairs of wings. go to #2 2. a. front wings thicker in texture than hind wings go to #3. b. front and hind wings are same texture throughout. go to #4 3. a. front wings are short order dermaptera b. front wings cover entire abdomen order coleoptera 4. a. wings with scale on all parts of their area. order lepidoptera b. wings without scales go to #5. 5. a. hind wings smaller than front wings. order ephemeroptera b. front and hind wings nearly equal in size. order odonata the insect pictured is in the order diptera. ephemeroptera. coleoptera. odonata.

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
