How does knowledge of location of brain damage aid our understanding of cognitive processes such as memory? In what ways did H.M contribute to our understanding of memory processes?

Different areas of the brain have different functions. So, knowledge of location of brain damage will give the exact position of the body which…

Compare and contrast parsimony, maximum likelihood, UPGMA and neighbor-joining methods.

According to Kant, why morality must be a priori? Explain the difference in Kantian ethics between immoral actions, actions in conformity with duty, and actions from duty in light of an example of your choice. What is the formula of humanity? Explain whether Robin Hood’s actions were moral or immoral according to the formula of humanity. Why, according to Kant, it is bad (immoral) to violate the principle of humanity?

Difference in Kantian ethics between immoral actions and actions in conformity with duty One example: Suppose the captain of a ship has experienced a…

What is utilitarianism? Explain, with your own words, the Master Argument for utilitarianism, i.e. how does it work. Explain the No Absolute Prohibition. How does a utilitarian respond to that objection? Does utilitarianism require us to be impartial? What does this amount to? In your opinion, is that a positive or a negative feature of the theory.

Utilitarianism is a doctrine which states that an act is morally correct if it maximizes utility and masses are in its favor. It is…

What type of data was obtained in Automated sequencing method. How was it different from the data obtained from Sanger’s method.

In Sanger’s sequencing method, data used to be collected on a gel. It was read manually. As an enhancement, in automated dideoxy sequencing method,…

The base-calling program outputs ‘N’ instead of designating a specific base. It does so when it is unsure of the exact base. What are the probable reasons which make the base-calling program unsure of a sequence.

The base-calling program becomes unsure of a sequence in the following conditions: Extremely broad peak: Sometimes the peak given in automated sequencing program is too…

What are the steps of Next Generation Sequencing (NGS).

In Next Generation Sequencing (NGS), extremely small DNA fragments can be sequenced. This makes this technique far better than shotgun sequencing. The various steps…

THE CONCEPT STICKY ENDS IN RECOMBINANT DNA TECHNOLOGY.

In DNA fragments have sticky ends, one end of one segment has a sequence complementary to any of the ends of the other segments….

Is shotgun sequencing more dependent on computer softwares in comparison to directed sequencing.

Your answer is ‘Yes’. In the shotgun sequencing method, “random DNA fragments” are sequenced. Then, by the use of specialized software and computerized machinery,…
