Question

We may not much like the fact, but we are 99.9 percent identical. This is because 99.9 percent of our DNA is common to every person, and the Human Genome Project is rightly celebrated for sequencing it. But what of the remaining 0.1 percent? It is far more significant than one might assume because if it was not for this minute percentage there would be no individual differences. We would be clones. These variations in the human code account for all individual idiosyncrasies. They are responsible for the differences between ethnic and racial groups. Perhaps most interesting of all, they also explain why some of us enjoy good health while others are more susceptible to many common diseases. It is thought that the mapping of the remaining 0.1 percent of human DNA will hasten the identification of new ways to treat common ailments such as obesity, cancer, and heart disease. The work will prove particularly useful in the search for new diagnostic tests, the customizing of treatments to best suit an individual’s genetic code, and ultimately the development of new drugs that target the DNA linked to a particular disease. The task of charting the inherited differences in the human genome has fallen to 200 scientists drawn from nine countries across every (populated) continent. They will screen people drawn from all the major human populations.    1 
 Q1. In the context of the passage the word sequencing refers to:

4 
 Q4. In reaching the conclusion that some of us enjoy good health while others are more susceptible to many common diseases, the author relies on which premise?

D. Why is the minute percentage of inherited differences significant?
E. How can mapping of the remaining 0.1 percent of human DNA help in the search for new diagnostic tests, customized treatments and new drugs?

Sajjad1994 · Answer

Official Explanation

Q1. In the context of the passage the word sequencing refers to:

Explanation

Sequencing is only mentioned in the passage in relation to the work of the Human Genome Project.

Answer: D

Sajjad1994 · Answer

Official Explanation

Q3. It can be inferred that the work will:

Explanation

It is stated that the mapping of human genetic differences will hasten the identitification of new ways to treat common ailments. It can be inferred that this will be possible because the map will accelerate the search for genes involved in common diseases. B and C are explicitly stated in the passage.

Answer: A

Q4. In reaching the conclusion that some of us enjoy good health while others are more susceptible to many common diseases, the author relies on which premise?

Explanation

It is the claim that some of our genetic differences explain our propensity for particular diseases, which supports the conclusion that some of us enjoy good health while others are more susceptible to many common diseases.

Pathshala · Answer

Q1. In the context of the passage the word sequencing refers to:

Second line of the paragraph mentions something about the "sequencing", "the Human Genome Project is rightly celebrated for sequencing  it ."
 It  refers to DNA. 
Now, Read the line again. The Human Genome Project is rightly celebrated for sequencing DNA.
Now, The question is who is doing the sequencing?
The answer is The human Genome project.
Let's see the options.

A. the human genetic code
 As per the passage, "variations in the human code account for all individual idiosyncrasies".
Now, read the sentence. variations in sequencing account for all individual idiosyncrasies
Does it make sense? No.
Reject the option.

B. the order in which things are repeated
 Very tempting answer choice, one can clearly mark this one.
But this seems more generic statement.
But if we look at the question, we have to find the answer in context of the passage.

C. a chart or map of the genetic differences between people
 The passage has used this line in context to 0.1 % of the DNA.
Which is not common, right?
Reject.

D. the work of the Human Genome Project
 Yes, this is what we have identified in the beginning.

E. the order in which amino acids are arranged in DNA.
 Is passage referring to amino acids anywhere?
Answer is No.

In q 3
I think an inference is a statement which is true under all conditions. Further, it can be a statement explicitly stated in the passage or not. Bottomline, whether it is a new statement or a repetition of some line in the passage, if it is true , then it must be an inference. so why B or C is incorrect?

Praval · Answer

In q 4
Can anyone tell me that why option C in incorrect?

Hello Sajjad,

Can I get a brief summary of the passage?

Sajjad1994 · Answer

Summary of the passage

While 99.9 percent of human DNA is shared among individuals, the remaining 0.1 percent accounts for crucial variations, influencing individual differences, ethnic diversity, and susceptibility to diseases. The Human Genome Project's sequencing of this small percentage is celebrated for its potential to identify new treatments and diagnostic tests for common ailments like obesity, cancer, and heart disease. A global team of 200 scientists is tasked with mapping the inherited differences across diverse human populations to advance personalized medicine and drug development.

Rosso · Answer

I have a question  Sajjad1994

"It is thought that the mapping of the remaining 0.1 percent of human DNA will hasten  the identification of new ways  to treat common ailments such as obesity, cancer, and heart disease."

How is this sentence infers to "accelerate  the search for genes involved  in common diseases"

To me, "identification of ways" and "search for genes" are quite different.
