Imagine you discover a yeast mutant that exhibits a general inability to grow and thrive compared to wild-type yeast. You predict that the mutant has a defect in a basic process necessary for survival and therefore examine the cellular levels of 200 common proteins, as well as the levels of tRNAs and rRNAs. You discover that tRNA and rRNA levels are normal, but the levels of all of the proteins you examine are much lower than they are in the wild-type yeast. This suggests that there is a general defect in:

punctuated equilibrium

Suppose that the genetic map distance from A to B is 8 map units, from B to C is 10 map units and from A to C is 2 map unit. A true-breeding wild type parent was crossed with a true breeding mutant parent. A three-point testcross has been performed using an F1 heterozygote, and 1000 progeny were obtained. How many of the test-cross progeny do you expect to be double crossover?

Answers

Answer:

This question includes the following options to choose from:

A) 2     B) 12     C) 8     D) 9     E) 10  

3 point testcrosses focus on analyzing the inheritance blueprints of alleles by crossing triple heterozygotes with triple recessive homozygotes, allowing therefore to find out the distance between the alleles, and also their location order on the chromosome.

And it all comes down to the frequency of recombination, in this case such frequency between C&A is 0.02, in the same fashion that it's 0.08 between A&B; thereby the answer is A). 2

List two chemicals that you think have low entropy and two that have high entropy. Explain the reason for your choices.

Answers

The Two substance that has low entropy are diamond and graphite while the other two chemical/substance that has high entropy are Noble gases(helium, neon, etc) and oxygen.

Generally, entropy measures the disorder or randomness in a system. High entropy implies randomness or high disorder while low entropy indicates orderliness.High entropy system, more energy is lost to the environment/surroundings.

Examples of chemicals or substances with high and low entropy are listed below

Low entropy

1.Diamond: This is a carbon crystalline substance. The makeup follows a well-structured pattern.  The particles are tightly packed thereby giving them a low entropy value. This means they are well ordered.

2.Graphite: This is another carbon substance but they have higher entropy than diamond but generally possess a low entropy.

High entropy

Generally, gaseous substances possess high entropy, and this includes

1. Nobles gases(helium, argon, Neon, etc); These gases when placed in a closed system they exhibit high entropy. They act disorderly. They move randomly and tend to occupy every space available in the system.

2. Oxygen gas: This is another gaseous substance that exhibits disorderliness when placed in a closed system.  

The arrangement of the particles and cohesive forces holding the individual particles of the substance together play a large role in determining its entropy.

Here are two examples:  

Low entropy: -A carbon crystal structure at a temperature near absolute zero,              

                      -A chunk of ice has low entropy

High entropy:- A box filled with two elements in their gaseous state, both of which are noble gases.

                       - Burning wood illustrates an increase in entropy  heated very          high temperature, with the gas "not very dense".

 The entropy of a chemical system depends on its energy and its multiplicity,  or how many different ways its atoms and molecules can be arranged. By adding new arrangements or energy, you increase entropy.  A diamond, for example, has low entropy because the crystal structure fixes its atoms in place. If you smash the diamond,  entropy increases because the original, single crystal becomes hundreds of tiny pieces that can be rearranged in many ways.

Burning wood illustrates an increase in entropy as The wood starts as a single, solid object.  Fire consumes the wood, releasing energy along with carbon dioxide and water vapor, and leaving a pile of ashes.  The atoms in the vapors and gases vibrate energetically, spreading out in an ever-expanding cloud.  Dissolving salt in water is another example of increasing entropy; the salt begins as fixed crystals,  and the water splits away the sodium and chlorine atoms in the salt into separate ions, moving freely with water molecules.  A chunk of ice has low entropy because its molecules are frozen in place.  Add heat energy and entropy increases. The ice turns to water, and its molecules agitate like popcorn in a popper.
