What makes DNA a stable carrier of genetic information?

DNA is a stable carrier of genetic information primarily due to its double helix structure and the hydrogen bonding between the complementary bases. The double helix provides a sturdy framework—two long strands of nucleotides wind around each other, creating a stable structure that protects the genetic information.

The hydrogen bonds that form between the complementary bases (adenine pairs with thymine, and guanine pairs with cytosine) are relatively weak individually but are numerous throughout the DNA molecule. This collective strength contributes to the overall stability and integrity of the DNA structure, making it resilient against environmental factors that could damage genetic information.

In addition to structural stability, the double helix configuration allows for effective replication during cell division and assists in error-checking mechanisms that preserve the accuracy of genetic transmission. Hence, this unique combination of structural characteristics makes DNA an effective and dependable carrier of genetic information.
