WebBy applying our model of biological membrane pattern for hydrophobic interactions, we postulate that hydrophobic forces constitute the necessary intermediate interaction between the unspecific electrostatic attraction for DNA phosphate groups and the very short-range interaction promoting hydrogen bonds. WebBriefly explain the structure and function of DNA. A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotides subunits. Each of these …
Explain the structure of DNA. Biology Questions - Toppr
WebMar 16, 2024 · Primary Structure: The primary structure of DNA is simply the sequence of nucleotides. The sugar-phosphate chain is called the DNA backbone, and it is constant throughout the entire DNA molecule. The variable portion of DNA is the sequence of nitrogenous bases. WebThis model for the DNA structure was widely accepted and is known as Watson and Crick's model of DNA. The three dimensional (3-D) double helix model of DNA as proposed by Watson and Crick including the latest advances in its structure is described below: DNA is a two-stranded molecule. It is made of two helical chains or strands that are ... filter torch
Watson and Crick Model of DNA - Biology Reader
WebSolution. Verified by Toppr. DNA is a double helical structure consisting of two long strands, coiled around a ventral axis. This structure was discovered by Watson and Crick. Each strand is a polynucleotide chain, composed of many nucleotides. Each is formed by a pentose, deoxyribose sugar, a phosphate group and one nitrogen base., WebSolution. Genes: Location -. On the chromosomes. Genes are segments of DNA. Function -. Transfer genetic information from parents to offspring. Genes are segments of DNA that carry information from parents to children and determine the hereditary characters in the offspring. Genes are organized and packaged in units called “chromosomes.”. WebJul 19, 2024 · As previously mentioned, Z-DNA can form when the DNA is in an alternating purine-pyrimidine sequence such as GCGCGC, and indeed the G and C nucleotides are in different conformations, leading to the zig-zag pattern.
