How is print looked up in the inheritance hierarchy?
So it is looked up in the inheritance hierarchy. print () is present in both classes P and Q, which of them should be called? The idea is, if there is multilevel inheritance, then function is linearly searched up in the inheritance hierarchy until a matching function is found.
Which is an important question on the molecular basis of inheritance?
Explore important questions on Molecular Basis of Inheritance for better understanding of the concept. Q.1. State the role of histones in DNA packaging. A.1. The basic histone proteins neutralize the acid nature of DNA. They play a role in gene regulation. They help the DNA to wind around itself. Also Read: DNA packaging. Q.2.
How is hierarchical inheritance different from Multilevel inheritance?
Hierarchical Inheritance: In this kind of inheritance, multiple classes extend a single class. Multilevel Inheritance: In the case of multilevel inheritance, a class is inherited by a class which again is inherited by another class, thereby forming a multilevel chaining mechanism of inheritances.
