Correct; specifically, pol encodes reverse transcriptase so you would be looking at antiretroviral drugs that specifically target RT.
Wow, that was a complete guess.
Okay, here's the next question (whew, this ended up being a long one. Sorry, but I hope you guys enjoy it!)
Image A is of Myrionecta rubra
Image B is of an unspecified heliozoan, that uses different means of locomotion from Myrionecta rubra
1a. What is the name of the cell part that Myrionecta rubra
uses for locomotion?
1b. What is the name of the cell part that the Heliozoan uses for locomotion? (Hint: be specific)
1c. What type of protozoan is the Heliozoan? A. Flagellate; B. Ciliate; C. Amoeboid; D. Apicomplexan/Sporozoan
2a. What type of microscopy was used in the creation of Image B? A. Brightfield; B. Phase Contrast; C. Differential Interference Contrast
2b. How can you tell? While referencing Image B, list two characteristics of the image you can use to differentiate between the technique you chose and the other two techniques listed in 2a. (Note: two characteristics in total)
3a. Using the following observations (all of which are true), create a hypothesis for Myrionecta rubra
's method of gaining nutrition. Be sure to reference at least 3 of the following observations in your answer:
Observation A: Myrionecta rubra
is known to produce large red blooms in coastal waters in the spring and fall.
Observation B: Myrionecta rubra
is a protozoan, but it can produce its own energy via photosynthesis.
Observation C: The principal food of Myrionecta rubra
are Cryptomonads, various types of photosynthetic algae.
Observation D: The nuclei of the Cryptomonads consumed by Myrionecta rubra
are retained for up to 30 days by Myrionecta rubra
, for the specific purpose of producing enzymes specific and necessary to the normal functioning of the Cryptomonads' chloroplasts.
Observation E: Genetic sequencing of Myrionecta rubra
reveals DNA from 3 distinct sources. However, upon repeating the genetic sequencing process with a sample of Myrionecta rubra
that has been removed from the ocean and placed into a sterile medium for about a month, DNA from only 2 sources is found.
3b. List the 3 sources of DNA described in observation E, and explain why one of them is no longer found one month after placing Myrionecta rubra
in a culture.
3c. What is the name for Myrionecta rubra
's method of gaining nutrition?
Bonus 1: Give an example of a type of genetic sequencing that might have been used in Observation E, and briefly explain how it works.
