The 5′ to 3′ direction of DNA strands within chromatids of metaphase chromosomes can be determined by using simultaneous hybridization of a single strand of the telomere probe and a single strand of a repetitive sequence to slides pretreated for strand-specific hybridization. The telomere probe ...
DNA replication is the biological process by which double-strand DNA gets replicated to produce two identical DNA structures. During DNA replication, it produces two strands namely, the leading strand and the lagging strand.Answer and Explanation: The leading strand is the parent strand of ...

The structure of DNA is a double helix, meaning it is made up of two strands. What is the orientation of these strands? What determines the direction of replication of DNA? What is the direction of lagging strand synthesis? A portion of one strand of DNA has the sequence 5' AATGGCTTA ...
The show said that Francis Crick, co-discoverer of the DNA, believed that life on Earth was designed by some higher power (aliens) because almost all strands of DNA rotate in only one direction (about the lengthwise axis of the strand) and thus they were engineered. Is this even true?
The article features the development of a process in separating DNA molecules of unprecedented size by scientist David Schwartz at Harvard University in Cambridge, Massachusetts. The method utilizes electrophoresis using pulse of a second and shearing electric field to the DNA strands in the gel ...
The 9-1-1 DNA checkpoint clamp is loaded onto 5′-recessed DNA to activate the DNA damage checkpoint that arrests the cell cycle. The 9-1-1 clamp is a heterotrimeric ring that is loaded in Saccharomyces cerevisiae by Rad24-RFC (hRAD17-RFC), an alternate

To solve the question of selecting the incorrect statement regarding DNA replication, we can follow these steps:1. Understand DNA Replication: - DNA replication is the process by which a parent DNA molecule is copied to pro
DNA replication is the process of the formation of a new DNA molecule from parent DNA. When a cell splits, the two new daughter cells must have the same genetic information, or DNA, like the parent cell. After a cell's DNA has been copied, it can split into two cells, each with ...
