A 5.0-μm strand of DNA carries charge +e per nm of length.Treating it as a charged line, what's the electric field strength 25 nm from the DNA,not near either end?

Answers

Answer 1

The electric field near an infinite line charge can be calculated and formulated such that

E= 2kλ/d

Here, k is the Coulomb constant and

λ is the line charge density, and d is the distance from the line charge.

Putting all the values in the given formula,

E= 1.15×10^8 N/C

What do you find DNA?

In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome.

Who discovered DNA?

The molecule now known as DNA was first identified in the 1860s by a Swiss chemist called Johann Friedrich Miescher. Johann set out to research the key components of white blood cells part of our body's immune system. The main source of these cells was pus-coated bandages collected from a nearby medical clinic.

Answer 2

It is possible to compute and express the electric field at an infinite line charge such that E= 2k/d. In this case, d is the distance from the line charge, k is the Coulomb constant, and is the density of the line charge.

E= 1.15×10^8 N/C

Why does DNA matter?

In eukaryotic organisms, the nucleus is a particular area of the cell where DNA is found.

Who made DNA possible?

Although the cell is fairly small, each creature's cell contains several DNA molecules. In the 1860s, a Swiss scientist named Johann Friedrich Miescher discovered the original discovery of the DNA molecule. Johann set out to look into the fundamental components of the white blood cells that make up our bodies' immune systems.

Your mother asked you to put water soluble fertilizer around the roots of her prize winning rose bush. The following week, you noticed the leaves of her rose bush are beginning to turn yellow and wilt. In terms of tonicity and water movement, explain why the rose began to die after the addition of fertilizer. Bonus: What can you do to solve this problem

Answers

Answer/Explanation:

The water soluble fertilizer that was added created a hypertonic environment. Concentration of solute is higher around the plant cells thereby leading to the movement of water molecule away from the cells of the rose bush. This is why the rise bush began to wilt as the leaves turn yellow.

Solution:

Give the plants a reasonable amount of water to cause the solution to be isotonic. When the amount of fertilizer and water is relatively balanced, the plants would be able to utilize the fertilizer, feed well and grow well.

1. What is a biogeochemical cycle?
2. What drives, or powers, the water cycle?
3. What causes water to condense and form clouds?

Answers

Answer:

1. In ecology and Earth science, a biogeochemical  cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.

2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.

3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.

The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete

Answers

Answer:

Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%

Explanation:

Available data:  

order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apart

The genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).

We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.  

We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.

We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,

DCO prob = recombination frequency A-B x recombination frequency B-C

                 = 0.1  x  0.03 = 0.003 = 0.3%

DCO prob = 0.3%

According to this, we would expect to find

0.15% AbC0.15% aBc

Now we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.    

SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%

SCO prob A-B = 9.7%

we would expect to find

4.85% Abc4.85% aBC

SCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%

SCO prob B-C = 2.7%

we would expect to find

1.35% ABc1.35% abC

The total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,

TCO= SCO A-B + SCO B-C + DCO

TCO prob = 9.7% + 2.7% + 0.3%

TCO = 12.7%
