Sugar-phosphate backbone
Wiki User
∙ 12y ago
Nucleotides are attached to each other through a sugar-phosphate backbone. The phosphate group of one nucleotide is attached to the sugar molecule of another nucleotide, forming a chain. Additionally, nucleotides are also attached to nitrogenous bases, such as adenine, cytosine, guanine, or thymine (in case of DNA) or uracil (in case of RNA).

For DNA polymerase to link nucleotides together as new strands of DNA the first nucleotide must be attached to what because DNA polymerase can only add nucleotides to a pre exsisting strand?
RNA Primer
What are the name of the four nucleotides?
cytosine, thymine, adenine, and guanine..
What are the components of thymine?
Thymine, like all nucleotides, is composed of three things: A five carbon sugar (ribose), a phosphate group attached to carbon #5 of the sugar, and the nitrogenous base (thymine) attached to carbon #1 of the sugar.
What is the name of the nucleotides have no DNA and no RNA?
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
Addenine and guanine are single-ringed purines?
Adenine and Guanine are just purines (the other nucleotides are pyrimidines), and these have one 6-parts ring with 3-parts ring attached.
What do you call nucleotides that are not attached to the DNA molecule?

What are free floating nucleotides?
transfer RNA, or tRNA Assuming this is the same this as free nucleotides (and it should be), they are nucleotides (the monomer of the polymer, DNA, made up of a phosphate, pentose sugar, and nitrogenous base) in the nucleus that are not attached to any strand of DNA or RNA, and thus literally "free floating" (i.e. floating in the nucleus not attached to anything and therefore "free")

What are the name of the four nucleotides?

what are the monomers of DNA?
The monomers of DNA are called nucleotides, and the polymer is a polynucleotide.There are four different nucleotides in DNA called A, T, G, and C for the nitrogenous base sidegroup (adenine, thymine, guanine, and cytosine respectively) attached to the sugar-phosphate backbone (deoxyribose-phosphate) of a nucleotide. These nucleotides can be joined in any order, permitting the "spelling" of an unlimited number of different genetic "words".
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.
DNA is built of billions of subunits called?
Nucleic acids consist of either one or two long chains of repeating units called nucleotides, which consist of a nitrogen base (a purine or pyrimidine) attached to a sugar phosphate.
Nucleotides are responsible for directing the addition of a particular amino acid to a polypeptide?
Essentially, yes. mRNA, which is made from nucleotides, have specific codons attached to them which codes for specific types of amino acids, which sort of guides the addition of amino acids to the polypeptide chain.
What is a subunit of a nucleic acid?
The subunit of a nucleic acid are nucleotides.
What is a riboprotein?
riboNucleoproteins are protein+RNA. The Ribo means it is RNA and not DNA (deoxyribo) nucleotides. Nucleotides (RNA or DNA) can hold onto proteins and subsequently react with substrates or attach to other macromolecules such as proteins. Some proteins will not work without nucleotides attached. Ribosomal proteins, on the other hand, are proteins that work with ribosomes. There are about 79 proteins that interact with ribosomes.
What are the components of thymine?
Thymine, like all nucleotides, is composed of three things: A five carbon sugar (ribose), a phosphate group attached to carbon #5 of the sugar, and the nitrogenous base (thymine) attached to carbon #1 of the sugar.
DNA is made of repeating units or monomers called?
nucleotides- guanine, adenine, thymine, and cytosine
