Explain step-by-step how DNA replication happens. How does DNA replicate? Describe how DNA replication is initiated, including how the DNA is made accessible for replication, and the molecules that are involved in permitting the initial generation of replicated DNA. ...

DNA Replication Process The trigger for DNA replication is the activation of a protein called helicase.Helicaseunwinds the DNA strands and breaks the hydrogen bonds between the nucleotides in either strand of DNA. This opens up the DNA and will allow DNA polymerase to read the DNA and create...
DNA:The deoxyribonucleic acid (DNA) is a large nucleic acid polymer in which two long strings of nucleotides bind to and wrap around each other, forming a double-helix. DNA contains all the genetic information of an organism and it is copied before cell division to assure that each daughter...
DNA Replication Essential Question: How do enzymes help ensure DNA is copied correctly? Why does DNA replicate? Cells copy genetic information before cell division so that each new cell has a complete set of DNA DNA replication occurs in the nucleus…WHY??
Watch this video of a cell going through the cell cycle stage of duplicating its genome twice without dividing. Bright points appear in the cell’s nucleus indicating where DNA is being replicated. Credit: Sergi Regot lab, Johns Hopkins Medicine ...
HiFi sequencing is a single-molecule, real-time sequencing technology (SMRT) that provides incredible single-molecule read accuracy across long reads of tens of kilobases in length or more. HiFi reads are generated by combining information from multiple observations of a single DNA molecule, resulting...
Humans attempted to reanimate the skulls of our dead for thousands of years. With the help of modern technology and ancient DNA, it’s now both an art and a science.
Topoisomerase activity is indispensible to cells, but requires the transient breakage of DNA strands. This property has been exploited, often for significant clinical benefit, by various exogenous agents that interfere with cell proliferation. Despite decades of study, surprising findings involving ...
They zeroed in on thesingle nucleotide polymorphism(SNP), or genetic variant, rs16969968, known as "Mr. Big" because it has been the mostly widely replicated genetic variant associated with smoking behaviors. Mr. Big is located in a gene called CHRNA5F (nicotinic acetylcholine receptor5) and ...
