What are the enzymes in DNA?
DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
What are the 4 enzymes that are important to DNA replication?
Enzymes involved in DNA replication are:Helicase (unwinds the DNA double helix)Gyrase (relieves the buildup of torque during unwinding)Primase (lays down RNA primers)DNA polymerase III (main DNA synthesis enzyme)DNA polymerase I (replaces RNA primers with DNA)Ligase (fills in the gaps)
What is the role of enzymes in DNA replication?
DNA polymerase enzymes bind to and dissociate from template DNA repeatedly during the replication or repair process. The number of synthesized nucleotides added by the DNA polymerase per one binding event is defined as processivity.
What is the first step of DNA replication quizlet?
The first major step for the DNA Replication to take place is the breaking of hydrogen bonds between bases of the two antiparallel strands. The unwounding of the two strands is the starting point. The splitting happens in places of the chains which are rich in A-T.
What are the two DNA components shown?
The two DNA components that are shown in the Gizmo include phosphates and nucleosides.
What makes up rungs of DNA?
The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases. Two of the bases are purines- adenine and guanine.
What are the four bases of DNA?
Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Is the five carbon sugar found in DNA?
The 5-carbon sugars ribose and deoxyribose are important components of nucleotides, and are found in RNA and DNA, respectively. The sugars found in nucleic acids are pentose sugars; a pentose sugar has five carbon atoms.
