The unwinding of the DNA molecule during replicationErhan S.doi:10.1016/0022-5193(69)90044-7Semih ErhanElsevier LtdJournal of Theoretical Biology
During DNA replication, the double-stranded DNA molecule is unwound and separated by an enzyme called___,along with other replication proteins. This process begins at specific DNA sequences called the origin of replication, where the DNA strands are ...
In DNA replication, refers to thepre-existing single strand of DNA that is copied into a new strand of DNA via complementary base pairing. How are the parental strands in a DNA molecule used in DNA replication? During DNA replication, each of the two strands that make up the double helix ...
c)Leading strand, due to the presence of multiple origins of replication on the DNA molecule. d)Lagging strand, due to the need for RNA primers to initiate DNA synthesis. There are 3 steps to solve this one.
In the DNA replication, the unzip (melting of hydrogen bonds) of the double stranded helix of DNA molecule occurs, and this reaction is carried out by... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our ...
They encircle the DNA molecule and slide on it freely and bidirectionally. Sliding clamps are typically associated to DNA polymerases and provide these enzymes with the processivity required to synthesize large chromosomes. Additionally, they interact with a large array of proteins that perform enzymatic...
Nucleosome assembly during DNA replication is tightly coupled to ongoing DNA synthesis. This process, termed DNA replication-coupled (RC) nucleosome assembly, is essential for chromatin replication and has a great impact on both genome stability maintena
Which molecule is active first during DNA replication? Why does DNA replication occur prior to mitosis? What DNA virus does not use the nucleus to replicate? Explain the process of replication of DNA and enzymes involved. What happens if there is a mistake in DNA replication?
In Escherichia coli two type II topoisomerases are involved in enabling both DNA replication and timely DNA segregation, namely Gyrase and Topoisomerase IV (TopoIV). Both of these enzymes work by first performing a transient double strand break in one molecule, then leading a second DNA duplex ...
1 ARTICLE NATURE COMMUNICATIONS | DOI: 10.1038/ncomms7439 The DNA-sliding clamp proliferating cell nuclear antigen (PCNA) is an essential factor in replication and repair that recruits polymerases and other DNA-modifying enzymes to the replication fork1. PCNA forms an 86-kDa homotrimeric ring2 ...
