Based on the Watson-crick model, a DNA molecule has two twisting strands of paired nucleotides. This allows the RNA to pair up as well, to transcribe the code to make protein.
The fluid mosaic model is commonly used to explain the structure and function of the plasma membrane. It describes the membrane as a fluid lipid bilayer with embedded proteins that can move laterally, giving the membrane its dynamic nature. The model helps illustrate how the plasma membrane controls the passage of substances into and out of the cell.
Watson and Crick's model of DNA's double helix structure helped explain how genetic information is stored and replicated. The model also provided insights into how mutations can occur and lead to genetic diversity.
The operon model attempts to explain how genes are regulated in prokaryotic cells. It describes how genes are grouped together into operons, which are clusters of genes that are transcribed together as a single mRNA molecule. The model also explains how the expression of these operons is controlled by regulatory elements such as promoters, repressors, and activators.
One of the key contributions of the punctuated equilibrium model is that it helps explain the pattern of evolution where long periods of stasis are interrupted by short bursts of rapid change. This model helps to account for the gaps and jumps in the fossil record by proposing that species experience most of their evolutionary change during speciation events, rather than gradually over time.
The double helix model of DNA helped explain how genetic information is stored and replicated in organisms. It also provided insight into how mutations occur and how variations in genes contribute to inheritance and evolution. Additionally, the structure of DNA as a double helix helped scientists understand how proteins are made based on the genetic code.
Fluid-mosaic model
The Fluid Mosaic Model is used to explain the components and properties of the plasma membrane. This model describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that can move and interact within the membrane.

Explain data model?
The nuclear model was insufficient because it couldn't explain the stability of atoms with more than one electron. It also failed to account for the continuous spectrum of light emitted by atoms in contrast to the discrete emission lines predicted by the model. Lastly, the model couldn't explain the chemical properties and behavior of elements accurately.
Dalton's model of the atom proposed that atoms of different elements have different masses and properties. In the case of gold and lead, their atoms have different numbers of protons, neutrons, and electrons, which influence their chemical and physical characteristics. This model helped explain why gold and lead have distinct properties despite being composed of atoms.
Properties of metals as high boiling point, high melting point, malleability, ductility, electrical conductivity, thermal conductivity, lustre are explained by the theory of metallic bonds.

De Broglie proposed that electrons in Bohr's model of the atom have wave-like properties, which helps explain the fixed energy levels.
