What is enzyme that is used to join complementary DNA nucleotides together?
DNA polymerase join complementary DNA nucleotides together while DNA ligase joins together the gaps left behind from the okizoki fragments. ...

What nucleotides can be held together by weak hydrogen bonds?
DNA is held together by hydrogen bonds. So most likely i believe that nucleotides are held together by these bonds because DNA consists of two nucleotides ...
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 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 already paired with the parent strands. Hence, DNA polymerase cannot link the first nucleotides in a newly synthesized strand. Instead, another enzyme, an RNA polymerase called primase, constructs an RNA primer, a sequence of about 10 RNA nucleotides complementary to the parent DNA template. DNA polymerase III recognizes the primer and adds DNA nucleotides to it to construct the new DNA strands. The RNA nucleotides in the primers are then replaced by DNA...
What are the functions of DNA polymerase and DNA ligase?
DNA Polymerase III adds new nucleotides to the strand being created. DNA Polymerase I replaces the primers with DNA nucleotides. Ligase joins the fragments together. ...
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. ...

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. ...
