2019年7月24日 · Deoxyribose is a five-sugar molecule called ribose that has lost an oxygen atom (deoxy-). This molecule connects to the nitrogenous base cross links, or rungs, of the DNA ladder. Label the base pairs: Each rung on the DNA ladder consists of one base pair, either adenine and thymine or guanine and cytosine. The chemical structures of these four ...

Deoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula H−(C=O)−(CH 2)−(CHOH) 3 −H. Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of a hydroxy group. Discovered in 1929 by Phoebus Levene, [2] deoxyribose is most notable for its presence in DNA.

2017年4月27日 · Deoxyribose is the five-carbon sugar molecule that helps form the phosphate backbone of DNA molecules. DNA, or deoxyribonucleic acid is a polymer formed of many nucleic acids. Each nucleic acid is composed of a deoxyribose molecule bound to both a phosphate group and either a purine or a pyrimidine.

2020年11月14日 · The first slide shows the basic structure of DNA where students label the nucleotides, deoxyribose, purines, phosphates, deoxyribose, and hydrogen bonds. Other slides go into detail about how replication occurs on the leading and lagging strand.

2023年9月13日 · DNA stands for Deoxyribonucleic acid, a macromolecule that carries genetic information in all living organisms, from the tiniest microorganisms to the most complex multicellular humans. DNA is a fundamental molecule that holds life’s blueprint.

A five carbon sugar called deoxyribose (Labeled S) A phosphate group (a phosphorous atom surrounded by four oxygen atoms.) (Labeled P) And one of four nitrogen-containing molecules called nucleotides .

1. On the image above, label: Phosphate. Deoxyribose. Hydrogen Bonds. Each of the four bases: adenine, guanine, cytosine, thymine. 2. The process by which DNA makes a copy is called: 3. What two scientists are credited with establishing the structure of DNA? 4. What is the shape of a DNA molecule? 5. The two sides of the molecule are said to be ...

the outside strands of a DNA molecule made of deoxyribose sugar and phosphate groups

The full name of DNA, deoxyribonucleic acid, because of the presence of sugar - deoxyribose. Deoxyribose is a modified form of another sugar called ribose. Ribose is the sugar in the backbone of RNA, ribonucleic acid.

A, G, C, and T refer to the 4 different nucleotides that are the basic building blocks of DNA. Nucleotides are composed of three components: a phosphate, a sugar, and a nitrogen-containing base. From the "Select Menu" choose "deoxyribose sugar". For a closer look at the sugar, examine the view "sugar (deoxyribose)".
