Two (short) DNA sequences are compared to judge the degree of relatedness of the organisms from which they were obtained. We will consider the random variable X= number of matching bases in corresponding positions on both sequences. For simplicity, we will ignore the possibility of insertions or deletions for this problem. The sequences to be compared are: (a) Suppose that the two pieces of DNA are random and unrelated. Then what is the distribution of the random variable X (state the name of the distribution and list its parameter(s))? On the other hand, if the sequences were related, then what would be a reasonable (qualitative not quantitative) assumption to be made about the distribution parameter(s)? (b) Formulate a null hypothesis and alternative (in terms of the distribution parameter(s) from part (a)). Our goal is to decide whether or not the two sequences are related. (c) Use R to graph the probability mass function (in form of a barplot) of the random variable X if the sequences are entirely unrelated (i.e., random) (d) Compute the p-value for this hypothesis test and formulate a conclusion at significance level α=0.05.
Answers
(a) Distribution of the random variable X when two pieces of DNA are random and unrelated:
The distribution of the random variable X when two pieces of DNA are random and unrelated is the binomial distribution. The parameter of this distribution is n, the sample size, and p, the probability of a success (i.e., a match).The probability of success (p) is equal to 1/4, since there are four possible nucleotides (A, C, G, T) and only one of them can match at each position. For two random sequences of length n, the expected number of matches is n/4. If the sequences were related, then a reasonable assumption would be that they have a higher degree of similarity, resulting in a larger value for p.
(b) Null hypothesis and alternative in terms of the distribution parameter(s) from part (a):
The null hypothesis is that the two sequences are random and unrelated. The alternative hypothesis is that they are related and have a higher degree of similarity, resulting in a larger value for p.(c) Probability mass function (in the form of a barplot) of the random variable X when the sequences are entirely unrelated:
To graph the probability mass function (in the form of a barplot) of the random variable X when the sequences are entirely unrelated, we can use the following R code: n <- 20 # sample sizep <- 1/4 # probability of successx <- 0:n # possible number of matchesy <- dbinom(x, size = n, prob = p) # binomial probabilitiesbarplot(y, names.arg = x, xlab = "Number of matches", ylab = "Probability", main = "PMF of X")(d) Calculation of the p-value and conclusion at significance level α = 0.05:
To calculate the p-value, we need to compute the probability of getting a value of X that is at least as extreme as the observed value (or more extreme) under the null hypothesis. Suppose we observe X = 16 for two sequences of length n = 20. Then the p-value is equal to P(X ≥ 16), which can be calculated as follows: p.value <- 1 - pbinom(15, size = 20, prob = 1/4) The p-value turns out to be 0.0298, which is less than the significance level α = 0.05. Therefore, we reject the null hypothesis and conclude that the two sequences are likely related.About DNADNA is a type of nucleic acid that has the ability to inherit properties.

The beads-on-a-string form of chromatin is known as which of the following?
a-The 300 nm extended chromatin
b-The 10nm fiber
c-The 30 nm solenoid
d-The 700 nm coiled chromosome
Answers
The beads-on-a-string form of chromatin is referred to as the 30 nm solenoid.
The beads-on-a-string form of chromatin refers to the structure formed when DNA is wrapped around histone proteins, creating nucleosomes that resemble beads on a string. This nucleosome structure is around 10 nm in diameter and represents the first level of chromatin compaction.
However, the 30 nm solenoid is the next level of chromatin organization that occurs when the nucleosomes further condense and fold into a more compact structure. This solenoid structure is formed by interactions between nucleosomes and results in a thicker fiber approximately 30 nm in diameter.
Therefore, the correct answer is c- The 30 nm solenoid.

a cat sees a mouse and pounces on it. do you think the internal signal to pounce could have been transmitted by a paracrine signal? give two reasons to explain why or why not?
Answers
It is highly unlikely that the internal signal to pounce in a cat could have been transmitted by a paracrine signal. Paracrine signals are signaling molecules that act locally on nearby cells, whereas the process of pouncing on a mouse involves a complex series of neurological and muscular responses that require precise coordination between various parts of the body.
Firstly, the internal signal to pounce involves a highly specific and coordinated response that is unlikely to be triggered by a simple paracrine signal. The process involves multiple signals from the eyes, ears, and nose that are integrated in the brain to produce a coordinated response. This response involves a series of muscular contractions that allow the cat to launch itself toward the mouse with precision and speed.
Secondly, the signals involved in pouncing on a mouse are likely to be transmitted through the nervous system rather than by paracrine signaling. The nervous system is responsible for transmitting signals throughout the body and coordinating complex responses such as pouncing. The use of paracrine signaling in such a complex process would be inefficient and ineffective.
In conclusion, while paracrine signaling plays an important role in many biological processes, it is unlikely to be involved in the complex process of pouncing on a mouse. The coordinated response involved in pouncing is likely to be mediated by the nervous system, which is better suited for transmitting signals over long distances and coordinating complex responses.

the process of phages carrying prokaryotic genes from one host cell to another is called by?
Answers
The process of phages carrying prokaryotic genes from one host cell to another is called by transduction.
Viruses that infect bacteria transport tiny amounts of chromosomal DNA from one bacterium to another "accidentally" via transduction. Yes, viruses can infect bacteria! Bacteriophages are viruses that infect bacteria. This is the method by which a virus or viral vector introduces foreign DNA into a cell. A viral transfer of DNA from one bacteria to another is an example of horizontal gene transfer.
Transduction is a method of transferring genetic information from one bacterium to another using a virus. The bacterial cells are not in direct touch with one another. Transduction and conjugation are two more methods of genetic recombination in bacteria. Inside the cell, the signals are then transmitted from one molecule to another, resulting in a specific cell response, such as cell division or cell death. Signal transduction is required for cells to develop and function correctly. Cells with aberrant signaling molecules may develop into cancer cells.

The application of constant pressure to an edematous (swollen) part of the body is an effective way of reducing the swelling. Which one of the following best explains why this works? A. The applied pressure opens precapillary sphincter muscles. B. The applied pressure adds to the pressure generated by the protein concentration gradient across capillary walls. C. The applied pressure opens one-way valves in arterioles. D. The accumulated fluid is sufficiently compressible that applying pressure reduces its volume directly.
E. The applied pressure causes local release of histamine, which causes mild inflammation and thus increased blood flow.
Answers
The best explanation for why applying constant pressure to an edematous part of the body reduces swelling is The applied pressure adds to the pressure generated by the protein concentration gradient across capillary walls.(B)
When an area of the body is swollen, fluid accumulates in the interstitial spaces due to an imbalance in the forces that regulate fluid movement across capillary walls. The main forces at play are the hydrostatic pressure within the capillaries and the oncotic pressure created by the protein concentration gradient.
By applying constant external pressure to the swollen area, you are effectively increasing the hydrostatic pressure outside the capillaries. This added pressure helps to counterbalance the forces causing fluid to leave the capillaries, promoting fluid movement back into the capillaries and reducing the edema.
Essentially, the applied pressure aids in reestablishing the balance between the hydrostatic and oncotic pressures, which helps to alleviate the swelling.(B)
