What are the two components the backbone the DNA molecule is made up of?
Alternating deoxyribose and phosphate molecules
Which componet of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
The part of a nucleotide that can be removed without breaking the chain is the thymine for DNA and the uracil for RNA. These two components are the nucleobases of a nucleotide.
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.
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 components parts of DNA?
Three main components. Deoxyribose sugar, a phosphate backbone for the structure and a nitogenous base. we are in three components of DNA because of hightech technology The groups are 1. Phosphate 2. Deoxyribose sugar 3. Nitrogen base The phosphates and deoxyribose sugars make up the sides of the "ladder" (alternating one after the other) and nitrogen bases are the "rungs" of the ladder. from kinneth Jane palaran see me in fb
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 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.

Which two molecular groups make up the backbone of dna?
deoxyribose and phosphate
Is backbone two words or one?
"Backbone" is one word.
Which two make up the backbone of DNA strands?
A deoxyribose sugar and phosphate groups.
What type of bond joins two nucleotides together to form a nucleic acid?
The connection between nucleotides is between the sugar of the first nucleotide and the phosphate of the second. These are covalent bonds yielding a covalently attached sugar-phosphate backbone.
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.
