How are nucleotides in DNA held together?

Nucleotides on the on the same strand are held together by covalent bonds to the sugar backbone of DNA. Nucleotides on separate strands are held together by complimentary hydrogen bonding.

Nucleotides are joined by a condensation reaction.

What is the function of DNA polymerases?

DNA polymerases are the enzymes responsible for joining DNA nucleotides together. In Prokaryotes - DNA Pol III is the enzyme which adds nucleotides to the new strand during DNA replication. DNA Pol I is responsible for replacing the primers with DNA nucleotides.

How often do errors occur in DNA replication?

One error occurs for every billion paired nucleotides added.

How is a gene related to the sequence of nucleotides?

Genes are segments of DNA. DNA is made up of polymer of nucleotides joined together. When there is an alteration in the sequence of nucleotides, gene mutation occurs.

Which enzyme synthesizes a short RNA primer at the beginning of each origin of replication?

DNA polymerase III can add nucleotides only to a chain of nucleotides that is alreadypaired with the parent strands. Hence, DNA polymerasecannot link the first nucleotides in a newly synthesizedstrand. Instead, another enzyme, an RNA polymerasecalled primase, constructs an RNA primer, a sequence ofabout 10 RNA nucleotides complementary to the parentDNA template. DNA polymerase III recognizes the primerand adds DNA nucleotides to it to construct the new DNAstrands. The RNA nucleotides in the primers are then replacedby DNA nucleotides.

What type of chemical reaction is used to put DNA nucleotides together to make DNA?

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.

What enzyme connects nucleotides together?

That depends on the process. During DNA replication, The nucleotides of the lagging strand (Okazaki fragments) are connected by DNA ligase. In transcription, the nucleotides of RNA are connected by RNA polymerase II.DNA Polymerse

How do you describe the basic structure of the DNA molecules?

DNA is composed of two strands of DNA nucleotides, arranged into a double helix, often referred to as a twisted ladder. The sides of the ladder are composed of alternating deoxyribose sugar molecules and phosphate molecules, and the rungs of the ladder are the pairs of nitrogen bases. The two strands of DNA nucleotides are held together by hydrogen bonds which form between the paired nitrogen bases.

What units are repeatedly joined together to form a strand of DNA?


What joins the nucleotides together?

Nucleotides join together in the DNA/RNA backbone via phosphodiester bonds. In DNA, base pairs loosely couple across the double-helix via hydrogen bonds.

Why are Adenine and Thymine and Guanine and Cytosine always paired together?

they are always paired together because when DNA is replicated they always find each other.

Nucleotide chains of DNA are held together by what?

Between nucleotides, there is a phosphodiester bond between the phosphate group of one nucleotide and the sugar of another nucleotide. Nucleotides (such as Adenine and Thymine) are held together on two strands of DNA through hydrogen bonding. This doesn't keep nucleotides together in a strand, but helps in the structure of two corresponding strands of DNA.

What are the enzymes responsible for joining the nucleotides of a new DNA strand together during replication?

DNA polymerases

How are the two bases linked together in DNA?

The paired bases of a DNA molecule are linked by hydrogen bonds.

What make up the DNA ladder?

the DNA ladder is made up of the nucleotides Adenine, cytosine, thymine, and guanine. These nucleotides are grouped together into pairs that make "rungs" on the ladder that are help together by a phosphate backbone.
