Describe DNA synthesis in detail

Answers

Answer:

DNA synthesis is the biological process by which a deoxyribonucleic acid (DNA) molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand.

Answer:

The discovery of the double-helical nature of DNA by Watson & Crick explained how genetic information could be duplicated and passed on to succeeding generations. The strands of the double helix can separate and serve as templates for the synthesis of daughter strands. In conservative replication the two daughter strands would go to one daughter cell and the two parental strands would go to the other daughter cell. In semiconservative replication one parental and one daughter strand would go to each of the daughter cells.

Through experimentation it was determined that DNA replicates via a semiconservative mechanism. There are three possible mechanisms that can explain DNA's semiconservative replication.

(a) DNA synthesis starts at a specific place on a chromosome called an origin. In the first mechanism one daughter strand is initiated at an origin on one parental strand and the second is initiated at another origin on the opposite parental strand. Thus only one strand grows from each origin. Some viruses use this type of mechanism.

(b) In the second mechanism replication of both strands is initiated at one origin. The site at which the two strands are replicated is called the replication fork. Since the fork moves in one direction from the origin this type of replication is called unidirectional. Some types of bacteria use this type of mechanism.

(c) In the third mechanism two replication forks are initiated at the origin and as synthesis proceeds the two forks migrate away from one another. This type of replication is called bi-directional. Most organisms, including mammals, use bi-directional replication.

10. At 100x, you will see a cell that is larger and has a dark shape in it. This cell doesn't look like the others because it is a
white blood cell and it functions to protect your body against microbes. Red blood cells do not have a nucleus. White blood cell
count is used as a diagnostic tool to determine if someone is sick. If you were fighting an infection, would you expect to have
more or less WBC's? Why?​

Answers

Answer:

More

Explanation:

When your body needs more of a cell, it produces more of that cell. Since WBC’s (white blood cells) are used to fight infections, if you are sick you need more of them. Hope it helps :)

how does a change in speed cause a wave to change direction​

Answers

When a wave enters a new medium at an angle, one side of the wave changes speed before the other side. This causes waves to bend. Bending occurs because the different parts of the wave travel at different speeds.

Answer:

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. ... The wavelength decreases as the light enters the medium and the light wave changes direction.

С The lizard population get more diverse as more generations go by.
D The lizard population shifts from being mostly brown to being most black.
!!

Answers

Answer: did you get the right answer ?

Explanation:

The statement is an accurate claim that can be made based on the lizard table, the lizard population shifts from being mostly brown to being mostly black. The correct option is D.

What is a population?

The term “population” refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.

Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.

We can see in the table that the population of lizards or black lizards is increasing, and the brown lizard population is decreasing.

Therefore, the correct option is D. The lizard population shifts from being mostly brown to being mostly black.

Makali and his parents recently emigrated from the highlands of Papua New Guinea. His family is part of the famous Fore tribe; after living in the tribe for most of their lives, they decided to give Makali a different life in the United States. His mother starts to cry as she recalls that both her parents died in the kuru epidemic that made the tribe famous, and she is terrified that Makali might be coming down with kuru. His father interjects to say that it is not possible and that he is far more concerned that Makali has some other infectious disease to which he had never previously been exposed.

His father says that Makali had a severe allergic reaction to the tetanus/pertussis booster shot as a child and has been unable to be re-vaccinated due to the risk of anaphylactic shock. Therefore, Makali may be susceptible to whooping cough (pertussis). This would not have been a concern 10 years ago, but vaccination rates for whooping cough have plummeted in the United States, eliminating herd immunity and sparking a return of the disease in some regions. Ironically, vaccination rates in the Fore tribe are much higher than in the United States, so Makali's parents had concerns about coming to the United States, which is falling behind other countries in this area of basic medical care!

One of the doctors you are working with says that checking immunoglobulin (Ig) levels should reveal if there is a serious infection. He also points out that kuru does not cause immunoglobin levels to rise. If Makali does have kuru, a brain biopsy may be required to make a definitive diagnosis.

1. Select the next step or steps that would be appropriate to diagnose Makali?
a. Test immunoglobulin (IgG, IgA, and IgM) levels in the blood for signs of infection.
b. Perform a brain biopsy.
c. Interview one of Makali's friends to ask about the day he first became sick.

2. Which statement most accurately describes the citric acid cycle?
a. It is an unregulated process, like an intersection without signal lights.
b. It is the main center of ATP production during anaerobic metabolism.
c. It plays a central role in key metabolic processes in the cell, with many metabolic intermediates leaving and entering.
d. It serves a catabolic role only, which is to generate ATP and reducing equivalents for cellular energy needs.

Answers

Answer:

Explanation:

It is important we understand what is immunoglobulin test.

Immunoglobulins, also known as antibodies, are measured by the test carried out in the blood. Antibodies are proteins produced by the immune system to combat pathogens such as viruses and bacteria that cause disease. Immunoglobulins are proteins produced by the body to combat various substances.

The immunoglobulin assay tests three forms of immunoglobulins in total. IgG, IgM, and IgA are the three types of antibodies. IgG, IgM, and IgA levels that are too low or too high may indicate a severe health condition.

Thus, from the above question; the next step that would be appropriate is:

Assuming the test uncovers an increase in immunoglobulin, it demonstrates contamination or infection. Thus, a fitting treatment ought to be begun against the infection.  

However, suppose the text doesn't uncover an increase in immunoglobulin and assuming he shows manifestations of symptoms, then the brain biopsy ought to be performed to affirm the diagnosis of kuru.

(2)

The citric acid cycle is the metabolic center of the cell. It is the doorway to the aerobic metabolism of any molecule that can be changed into an acetyl group or a part of the citric acid cycle. The cycle is additionally a significant wellspring of prototype for building blocks of numerous different molecules like amino acid and nucleotide base.

Thus, the best accurate statement is: Option C

You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts. You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed.
