Which componet of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
The phosphate group can be removed from a nucleotide without breaking the polynucleotide chain within a DNA molecule. The phosphate group is attached to the 5' carbon of the sugar molecule in a nucleotide through a phosphodiester bond, which does not affect the backbone of the DNA chain when cleaved.
What are the two components the backbone the DNA molecule is made up of?
Alternating deoxyribose and phosphate molecules
Why does the DNA backbone not line up at each end?
The structure of DNA can be compared to a ladder. It has an alternating chemical phosphate and sugar backbone, making the "sides" of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). (A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the "rungs" of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.
Where do you find phosphodiester bonds?
Phosphodiester bonds are commonly found in nucleic acids, such as DNA and RNA. These bonds form between the phosphate group of one nucleotide and the hydroxyl group of another nucleotide, creating the backbone of the nucleic acid molecule.
Explain how a double helix is similar to a spiral staircase?
Two strands of DNA intertwined together and twisted to form a double helix. The sugar phosporous backbone is like the side of the stairs and the nucleotide bases are like the steps of the stairs.
What are the two components that make up of the backbone of the DNA?
Sugar and phosphate are the parts that make up the DNA backbone.

The backbone of two DNA molecules are made up of what two components?
deoxyribose sugar and a phospahte
What are the two components the backbone the DNA molecule is made up of?
Alternating deoxyribose and phosphate molecules
What represents the portion of DNA composed of the nucleotides' phosphate groups?
The back-bone of DNA is called 'the sugar-phosphate backbone' because: the ribose [or the 2' [two-prime] deoxy-ribose] sugars that 'make up' the backbone binding portion of the (one of four) nucleotide bases is interlaced with the phosphate moieties. Compare to adding N to the C chain to gain strength.

What are the two chemical groups that form the backbone of a DNA strand?
The two chemical groups that form the backbone of a DNA strand are deoxyribose sugar and phosphate groups. These components link together to form a sugar-phosphate backbone, with nitrogenous bases attached to the deoxyribose sugar.
Which two molecular groups make up the backbone of dna?
deoxyribose and phosphate
Where do you find phosphodiester bonds?
Phosphodiester bonds are commonly found in nucleic acids, such as DNA and RNA. These bonds form between the phosphate group of one nucleotide and the hydroxyl group of another nucleotide, creating the backbone of the nucleic acid molecule.
Is backbone two words or one?
"Backbone" is one word.
What is the type of bond that links two nucleotides together in a strand of DNA?
Gangnam Style
