HIV's genome of RNA includes the code for reverse transcriptase (RT), an enzyme that acts early in infection to synthesize a DNA genome off of an RNA template. The HIV genome also codes for protease (PR), an enzyme that acts later in infection by cutting long viral polyproteins into smaller, functional proteins. Both RT and PR represent potential targets for antiretroviral drugs. Drugs called nucleoside analogs (NA) act against RT, whereas drugs called protease inhibitors (PI) act against PR. Which of the following treatment options would most likely avoid the evolution of drug-resistant HIV (assuming no drug interactions or side effects)?(a) Use a series of NAs, one at a time, and change about once a week.(b) Use a single PI, but slowly increase the dosage over the course of a week.(c) Use high doses of NA and a PI at the same time for a period not to exceed one day.(d) Use moderate doses of NA and two different PIs at the same time for several months.

Suppose Sally grew a wild type E. coli culture in rich liquid media that contained all 20 amino acids until the culture was dividing exponentially, with one cell division approximately every 20 minutes. She then added the mutagen 5-bromouracil to the media. After the cells had grown for 20 more minutes, she washed the cells to remove the mutagen and resuspended the washed cells in sterile water. Next, Sally plated the resuspended cells on minimal media supplemented with tryptophan and obtained well-separated colonies, such that each colony arose from a single bacterial cell. She replica-plated these colonies on minimal media and selected a single colony that grew on the media supplemented with tryptophan, but not on minimal media.
Sally inoculated 10 test tubes containing fresh minimal media supplemented with tryptophan with cells from this colony and grew the 10 cultures until the cells were dividing exponentially. She then plated 0.1 mL of each culture onto separate plates containing minimal media.
No colonies grew on 3 of the 10 plates. Colonies grew on the remaining seven plates, with one plate containing about 100 colonies and the other plates each containing between 1 and 15 colonies. What type of mutation allowed colonies to grow on these seven plates?
a) spontaneous forward mutation
b) spontaneous reverse mutation
c) induced forward mutation
d) induced reverse mutation

Answers

Answer:

b) spontaneous reverse mutation

Explanation:

Spontaneous mutations are produced by natural biological processes, while induced mutations are produced by mutagenic agents that trigger nucleotide errors in the DNA sequence. In the first phase of the experiment, Sally generated an induced mutation by using 5-bromouracil. The resulting strain required a constant supply of tryptophan to grow.

A reverse mutation restores the wild-type phenotype modified by a forward mutation, thereby reversing the phenotypic alteration to its original state. In a second step of the experiment, the colonies grew without the supply of tryptophan, thereby evidencing that the mutation was reversed in the original colony.

If a star is 300 light-years from Earth, how long does it take light from that star to reach Earth? 300 light-years 300 years 300 hours 300 days

Answers

If a star is 300 light-years from Earth, it will take 300 light years from that star to reach Earth. So, the correct option is A.

What is Light year?

A light year is defined as the larger unit of length used to express astronomical distances which is approximately equal to 9.46 trillion kilometers or 5.88 trillion miles.

A light year is explained as a measure of distance and not as time where light travels at a speed of 300,000 km/s where the distance that light will travel in one year is considered as a light year which is 9.4611012 is equal to km. When a star is 300 light-years from Earth, it will take 300 light years from that star to reach Earth.

Therefore, the correct option is A.

Match the characteristic of the biome to the type of rainforest

Answers

The rainforest biome develops in warm and humid areas, its characteristics are abundant rainfall and temperatures between 19 and 28° C.

What are the characteristics of rainforest biomes?

It is a biome with very dense vegetation, with a wide variety of species whose importance has to do with the amount of carbon it stores, which is essential to prevent soil erosion.

Among its main characteristics are its high average temperatures, as well as its abundant rainfall, which is constant throughout the months.

Therefore, we can conclude that the rainforest biome develops in warm and humid areas, its characteristics are abundant rainfall and temperatures between 19 and 28° C.
