BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Double helix, as related to genomics, is a term used to describe the physical structure of DNA. A DNA molecule is made up of two linked strands that wind around each other to resemble a twisted ladder in a helix-like shape. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

Detailed explanation-2: -The structure of DNA is a double-helix polymer, a spiral consisting of two DNA strands twisted around each other. James Watson and Francis Crick determined this structure in 1953, building upon almost a century’s worth of research from the scientific community.

Detailed explanation-3: -The structure of DNA is a double helix. In other words, it is a double stranded molecule that twists like a spiral staircase. The outsides of the molecule, the railings of the staircase, are made of deoxyribose sugars alternating with phosphates. This part of the molecule is sometimes called the “backbone".

Detailed explanation-4: -Its double helix consists of two spiral chains of DNA. This double helix shape is often visualized as a spiral staircase. The twisting of DNA is the result of both hydrophilic and hydrophobic interactions between the molecules that comprise DNA and water in a cell.

Detailed explanation-5: -The structure of DNA is called a double helix because each of the two strands of DNA resembles a helix in shape. A helix is a winding structure that looks like a spiral staircase. The DNA double helix is held together by hydrogen bonds that exist between the nitrogenous bases in each strand.
