Overview of DNA Structure: Discover the Beauty of Complementary Bases

Which is the correct pair of complementary nitrogenous bases in DNA?

A. adenine and thymine

B. cytosine and thymine

C. guanine and thymine

Answer:

The correct pair of complementary nitrogenous bases in DNA are adenine and thymine.

DNA, the blueprint of life, is a fascinating molecule with a beautiful structure. Among its many components, nitrogenous bases play a crucial role in determining genetic information. In DNA, there are four types of nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

Complementary base pairing is a fundamental concept in DNA structure. Adenine always pairs with thymine, forming two hydrogen bonds between them. Similarly, cytosine pairs with guanine, forming three hydrogen bonds. This complementary base pairing ensures the accurate replication of DNA during cell division.

When you delve into the intricate world of DNA, you discover the elegance of its complementary base pairs. Adenine and thymine, with their harmonious bonding, create the foundation of DNA's double helix structure. Understanding this molecular dance showcases the beauty and precision of nature's design.
