What is the nucleotide sequence of the complementary strand of the DNA molecule?
DNA and RNA base pair complementarity
| Nucleic Acid | Nucleobases | Base complement |
|---|---|---|
| DNA | adenine(A), thymine(T), guanine(G), cytosine(C) | A=T, G≡C |
| RNA | adenine(A), uracil(U), guanine(G), cytosine(C) | A=U, G≡C |
What type of bond holds one strand of DNA to the complementary strand of DNA quizlet?
DNA is made up of two nucleotide strands. The nucleotides are connected together by covalent bonds within each strand.
What adds complementary nucleotides?
The enzyme DNA polymerase moves along the exposed strands and adds complementary nucleotides to each nucleotide in each existing strand.
What adds nucleotides in DNA replication?
One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.
What is the mode of replication in E coli?
DNA is not replicated conservatively in E. coli but it is replicated semi-conservatively as out of the two strands of the daughter DNA, one strand comes from the parent DNA. Thus, the mode of DNA replication in E. coli is semi-conservative and bidirectional.
What protein is responsible for initiating DNA replication in E coli?
DnaA
What protein is responsible for initiating DNA replication?
The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain. However, DNA replication is much more complex than a single enzymatic reaction.
How many enzymes or proteins are concerned with DNA replication in E coli?
coli has four more enzymes, DNA polymerase II, III (Table. 28.1), IV and V; DNA polymerase III (Pol III) is concerned with DNA replication, while the remaining four enzymes are involved in DNA repair.
Which enzyme is responsible for unzipping?
DNA helicase
What is the name of the enzyme that unzips the DNA?
helicase enzyme
