What two things make up the backbone of a DNA molecule?

Answer 1

DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called nucleobases (informally, bases). It is the sequence of these four nucleobases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA in a process called transcription.

Answer 2

In simple terms; the backbone of DNA is made up of a phosphate group and a pentose sugar. The pentose sugar is also known as Deoxyribose and makes up the Din DNA (Deoxyribose Nucleic Acid).

Answer 3

A DNA molecule is made up of numerous genes and are found on chromosomes. DNA contains monomers called nucleotides, which is made up of a phosphate group, a deoxyribose sugar, and a nitrogenous base. These nucleotides connect together to form the double-stranded structure, called the double helix. The double helix structure was founded by Watson & Cricke.

Answer 4

Phosphate molecules and deoxyribose sugar.

Answer 5

Phosphate PO4-- molecular groups and 2'deoxy-ribose sugars, in an alternating configuration.

Answer 6

Alternating deoxyribose and phosphate molecules

Answer 7

The phosphate moieties are conjoined with ribose [5 carbon] sugar molecules.

Answer 8

Sugar and phosphate are the parts that make up the DNA backbone.

Answer 9

A deoxyribose and a phosphate group. Deoxyribose molecules are linked by phosphodiester bonds.
