  • Kỹ thuật RFLP là kỹ thuật nghiên cứu tính đa hình chiều dài của các phân đoạn DNA dựa trên điểm cắt các enzim giới hạn. Khi ủ DNA với enzim giới hạn ở dung dịch đệm thích hợp ở pH, nhiệt độ thích hợp sẽ sẽ tạo ra những phân đoạn DNA với kích thước khác nhau, từ đó lập nên các bản đồ gen. Tham khảo chương hai "Kỹ thuật RFLP - Restriction fragment length polymorphisms" để hiểu hơn về vấn đề này.

  • As Vietnam has rich resources of local chicken breeds, some of them are known having a certain level of infectious disease resistance. Knowledge of the single-nucleotide polymorphism in exon 14 of the chicken Mx gene will facilitate further researches on the resistant activity of Mx gene and its use for breeding of influenza virus resistant chicken varieties. This study aimed to investigate the exon 14 polymorphisms of the Mx gene in some representative indigenous chicken breeds collected from different locals in Vietnam.

  • Certain phenomena resist coverage within the Lambek Calculus, such as scopeambiguity and non-peripheral extraction. I have argued in previous work that an extension called Polymorphic Lambek Calculus (PLC), which adds variables and their universal quantification, covers these phenomena. However, a major problem is the absence of a known decision procedure for PLC grammars. This paper proposes a decision procedure which covers a subset of all the possible PLC grammars, a subset which, however, includes the PLC grammars with wide coverage. ...

  • In this study, we designed two PCR primers to amplify the region containing rs6548238. The AvaI restriction enzyme was selected to detect the SNP polymorphism. Sequencing the resulting bands validated the RFLP method. In conclusion, RFLP method is simple, sensitive and cost effective for genotyping of the TMEM18 rs6548238 polymorphism; thus, this method is most convenient for SNP analysis in large-size samples from Vietnamese population.

  • In the language of C++, a class that is inherited is called a base class. The class that does the inheriting is called a derived class. Therefore, a derived class is a specialized version of a base class. A derived class inherits all of the members defined by the base class and adds its own, unique elements. C++ implements inheritance by allowing one class to incorporate another class into its declaration. This is done by specifying a base class when a derived class is declared. Let’s begin with a short example that illustrates several of the key features of inheritance....

  • Polymorphism is the ability that helps in executing different operations in response to the same message. In OOP, you can implement polymorphism by creating more than one function within a class that have the same name. The difference in the functions lies in the number and the types of parameters passed to each function. This chapter introduces the concept of polymorphism. It explains how to implement function overloading and operator overloading.

  • This module discusses three features of C++ that directly relate to object-oriented programming: inheritance, virtual functions, and polymorphism. Inheritance is the feature that allows one class to inherit the characteristics of another. Using inheritance, you can create a general class that defines traits common to a set of related items. This class can then be inherited by other, more specific classes, each adding those things that are unique to it. Built on the foundation of inheritance is the virtual function.

  • Inheritance and Polymorphism Welcome to the module Inheritance and Polymorphism. Inheritance is a process of creating a new class from an existing class. Inheritance allows you to inherit attributes and methods of the base class in the newly created class.  Polymorphism is a feature of OOP that allows the data members of a class to behave differently based on their parameters and data types. In this module, you will learn about: Implementing Inheritance
