Replacing your home's windows to improve its overall resale value is an investment to consider carefully. For the average-sized U.S. home, installing an entire set of brand-new windows can easily cost more than $10,000.
A molecule of DNA is double-stranded. The molecule has the shape of a double helix, typically right handed (B form DNA).The DNA molecule consists of two complementary strands oriented in an antiparallel fashion. Each strand is composed of nucleotides.he twisted ladder metaphorA DNA molecule is often likened to a spiral (or twisted) ladder. In this analogy, the rungs of the ladder are the base pairs (A-T and G-C). The sides of the ladder are the sugar-phosphate backbones of the two strands. This refers to B form DNA.
Best Answer: DNA is a double helix structure which means two strands of nucleic acid molecules intertwining each other. RNA is a single strand of nucleic acid molecules.n DNA molecule, the sugar is 2â²-deoxyribose and in RNA molecule-ribose. The sugars comprise the backbone of every DNA or RNA chain, linked by covalent phosphodiester bond between 5â²- and 3â²-carbons of two adjacent sugars.
