- Modified true or false. Encode the word true if the statement is correct. If the underline word/s is incorrect, then correct the underlined word/s that makes the statement wrong by encoding the correct answer beside false. Answers must be encoded in capital letters 1. When Grammia incorrupta caterpillars are infected by a parasitoid, they show an increased preference for acidic toxins found in larval food plants, and by choosing to eat these toxic plants when infected, are able to increase survival.True or false? wild type fast plants propagate mostly via self pollination transfected beta-galactosidase requires antibiotics to be expressed properly. the bradford assay allows you to determine the concentration of proteins produced fromtransfected DNA1) Complementation occurs when auxotrophic organisms provide a wildtype allele that another auxotroph is lacking to produce a needed molecule for a chemical pathway. The wt allele can be passed on through horizontal gene flow, or the interaction of the auxotrophs during reproduction produces an offspring with a 'rescued' phenotype due to independent assortment returning favorable recombination of function alleles. If a researcher interacts four auxotrophs, and mutant -1 complements mutants -2, -3, and -4, and mutant -2 complements mutants -3 and -4, and mutant -3 complements -4, how many genes are indicated? a) Four genes! b) One gene with four alleles! c) Three genes with one allele. d)A complementation chart was not provided so I cannot answer this question. 2) An inheritance ratio of 12:3:4 is a sure indication of: a) Incomplete assortment. b) A dihybrid example of codominance. c) Dominant epistasis. d) Recessive epistasis.
- Anophelesmosquito life cycle: https://www.cdc.gov/mosquitoes/about/life-cycles/anopheles.html Culexmosquito life cycle: https://www.cdc.gov/mosquitoes/about/life-cycles/culex.html Look at the life cycle of the two mosquito vectors involved in malaria and West Nile virus transmission. Consider the details of their biology in terms of: 1) habitat of different stages, 2) duration of life cycle, 3) food needs, 4) feeding preferences, 5) how far they disperse. Below write out how each might be a useful aspect to consider in terms of controlling the insect and /or its ability to transmit the disease to humans. Anopheles 1. 2. 3. 4. 5. Culex 1. 2. 3. 4. 5.Prototrophy is often the phenotype selected to detecttransformants. Prototrophic cells are used for donorDNA extraction; then this DNA is cloned and the clonesare added to an auxotrophic recipient culture. Successfultransformants are identified by plating the recipientculture on minimal medium and looking for colonies.What experimental design would you use to make surethat a colony that you hope is a transformant is not, infact,a. a prototrophic cell that has entered the recipientculture as a contaminant?b. a revertant (mutation back to prototrophy by a secondmutation in the originally mutated gene) of theauxotrophic mutation?for clarification which is shown in the graph, the darker blue on the bar graph shows the mass(size) of the eggs and the striped blue represents the number of eggs which is also depicted in the graph. as far as the host plants, its just showing 3 different plants the butterflies were on which is represented by the a, b, and c, also located on the graph. The right side of the graph (mass) represents blue and the left side (number of eggs) represents the striped blue. part a: Describe the relationship between egg size and clutch size shown in Figure 1. (This is not asking about host plants, just about the butterfly eggs.) part b: Describe one possible reason for the relationship between egg size and clutch size observed. (This is not asking about the host plants, just about the butterfly eggs.) part c:Describe one realistic difference between host plants that might be affecting the numbers and sizes of eggs that a female lays on these plants.
- In 2006, there was a sudden, unexplained die-off of honeybee colonies throughout the United States. The die-off was economically significant because one-third of the human diet comes from insect-pollinated plants, and honeybees are responsible for 80% of the pollination. In October of 2006, the sequence of the honeybee genome was reported. Interestingly, the genome was found to contain far fewer cytochrome P450 genes than do the genomes of other insects. Suggest how the die-off and the paucity of P450 genes may be related.Briefly speculate about the implications of the results shown in “Figure 2.pdf” by thinking about how the diversity of Rab proteins might have arisen in this species.
