Structure Of Dna – FAQ
DNA, or deoxyribonucleic acid, is composed of two long strands forming a double helix. These strands are made up of simpler molecules called nucleotides, each consisting of a sugar, a phosphate group, and a nitrogenous base. The bases pair specifically: adenine with thymine, and cytosine with guanine, creating a ladder-like structure within the helix.
The double helix structure of DNA is crucial because it allows for efficient storage and transmission of genetic information. The specific pairing of the bases ensures accurate replication during cell division. Additionally, the helical shape provides stability and protects the genetic code from damage.
DNA replication occurs through a semi-conservative process. The double helix unwinds, and each strand serves as a template for the formation of a new complementary strand. Enzymes like DNA polymerase facilitate the addition of nucleotides, ensuring that each new DNA molecule contains one original and one new strand.
Hydrogen bonds are essential in maintaining the stability of the DNA double helix. They form between the nitrogenous bases: adenine pairs with thymine via two hydrogen bonds, and cytosine pairs with guanine via three hydrogen bonds. These bonds, while relatively weak individually, collectively provide the necessary stability for the DNA structure.
Yes, the structure of DNA can be altered through mutations, which can occur naturally or due to environmental factors. Mutations can lead to changes in the genetic code, which may result in various effects ranging from benign to harmful. Some mutations can cause genetic disorders or increase susceptibility to diseases, while others can drive evolution and adaptation.
