Dna structure quick lab 8.a1-a2 answer key
1 answer:
The DNA structure can be a twisted ladder. The image above shows what is referred to as this structure's double-helix shape. It is a nucleic acid, and nucleotides are the building blocks of all nucleic acids. Each nucleotide, which makes up a portion of the DNA molecule, is made up of three separate substances, including sugar, phosphate groups, and nitrogen bases.
Nucleotides, which consist of a sugar group, a phosphate group, and a nitrogen base, are the fundamental components of DNA. Each DNA strand is made up of nucleotides that are joined by the sugar and phosphate groups. There are four distinct categories of nitrogen bases: adenine (A), thymine (T), guanine (G), and cytosine (C). The pairings of these four nitrogenous bases are as follows: A with T and C with G. The DNA's double helix structure, which resembles a twisted ladder, depends on these base pairs. The genetic code or DNA's instructions are determined by the nitrogenous bases' order.
Sugar is one of the three structural elements of DNA that form the DNA molecule's backbone. Additionally known as deoxyribose. A ladder-like structure is created when the nitrogenous bases of the opposing strands establish hydrogen bonds. DNA backbone structure See in the figure.
