Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): DNA copying is necessary during reproduction.
Reason (R): DNA copying leads to the transmission of characters from parents to offspring.
To understand the relationship between the assertion and the reason given, let's break down each statement and analyze them individually.
Assertion (A): DNA copying is necessary during reproduction.
DNA copying, also known as DNA replication, is indeed necessary during reproduction. Reproduction is the process by which new individuals of the same species are produced. In order for the offspring to inherit the characteristics of their parents, it is essential that the genetic material, which is encoded in DNA, is accurately copied and transmitted to the next generation.
Reason (R): DNA copying leads to the transmission of characters from parents to offspring.
The reason provided is also correct. DNA copying, or DNA replication, ensures the transmission of characters from parents to offspring. During DNA replication, the double-stranded DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical copies of the DNA molecule. When these replicated DNA molecules are passed on to the offspring, they carry the same genetic information as the parent, allowing for the transmission of characters.
Explanation of the relationship between the Assertion and the Reason:
The reason provided in statement (R) correctly explains why DNA copying is necessary during reproduction. DNA replication ensures the accurate transmission of genetic information from parents to offspring, which is essential for the inheritance of characters.
Therefore, the correct choice is:
Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
