The two molecules that alternate to form the backbone of a polynucleotide chain are?

Like DNA, the backbone of RNA consists of a sugar molecule and a phosphate group; the difference is that in RNA the sugar is ribose, whereas in DNA it's deoxyribose.

What is a polynucleotide?
Polynucleotide is a molecule that is usually in DNA and RNA. It is biopolymer composed and usually has thirteen or more nucleotides.
What is the difference between an endonuclease and an exonuclease?
an exonuclease cleaves nucleotides from the end of a polynucleotide chain whereas an endonuclease cleaves nucleotides from within a polynucleotide chain
The coiling of the protein chain backbone into an alpha helix is referred to as?
The coiling of the protein chain backbone into an alpha helix is referred to as the secondary structure. It is composed of several polypeptide chains.
Which linkage breaks lysozyme in bacterial cell wall?
Bacterial cell walls contain a layer of peptidoglycan, which is the specific site that lysozyme attacks.The layer contains alternating molecules called N-acetylglucosamine and N-acetylmuramic acid.These molecules form a strong chain that acts as the backbone for the cell wall. The link between the two is cleaved by lysozyme. Once this chain is broken by lysozyme, it results in bacterial death.
What is a DNA backbone?
A backbone molecule is the unchanging part of a molecule, which are linked together in a chain-like fashon. For example: An amino acid molecule consists of an amino group (usually featured on the left hand side), and a carboxyl group (usually featured on the right hand side) bound to a central (alpha) carbon atom. That is the basic (non-changing) part of the amino acid. However, to the central (alpha) carbon there is a Hydrogen atom, and a side chain (or function group) are attached (bound). That side chain is different for every amino acid, thus giving a unique property to each and every one of them. These amino acid molecules are linked together by peptide bonds, leading to the formation of a protein molecule. Since the the basic molecule parts (amino group, alpha carbon, carboxyl group) are linked to each other, forming a chain, that is what is considered as the "protein backbone". Similarly, other molecules can form a "backbone" . Other examples are: sugar-phosphate backbone in DNA, carbohydrate backbones in polysaccharide. More info can be found under related links

In the triglyceride molecule shown below what are the three molecules attached to the glycerol molecule A.Nucleic acids?
The three molecules attached to glycerol backbone are long chain fatty acids.
Which element forms the backbone of all organic molecules?
Carbon. Organic molecules are usually made up of carbon chains or rings, with hydrogen atoms bonded to most bond sites. The molecules are distinguished by the length of the chain, the number of double or triple carbon-carbon bonds, and the other elements or ligands that might be bonded to the carbon chain or ring.
Is nucleic acid a long chain of simple sugars?
DNA and RNA are both forms of polynucleotide. This means that they are long molecules made up of many individual monomer units. The basic monomer unit of a polynucleotide is a nucleotide. The three primary components of a nucleotide are the phosphate group, the pentose sugar and the nitrogenous base. In DNA, the pentose sugar present in the nucleotides is deoxyribose. In RNA, the pentose sugar present in the nucleotides is ribose. In DNA, the four bases present are adenine, thymine, guanine and cytosine. In RNA, the base uracil replaces the base thymine. DNA is also a double-stranded polynucleotide, whereas RNA is a single-stranded polynucleotide.
What is an example of chain molecules?
An example of chain molecules would be...
Which component of a nucleotide present within a DNA molecule could be removed without breaking the polynucleotide chain?
all i know is that its not phosphate
What forms the backbone of the DNA double helix molecule?
The backbone of a DNA chain is sugar and phosphate groups of each nucleotide.
Backbone of Italy?
