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 ...
There are two types of DNA strands such called the leading strand and lagging strand. The two strands have the opposite orientation and form a helix. During DNA replication, several enzymes are required like helicase, primase, polymerase, and ligase. After the replication process, two distinct ...
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 ...
I take anything those shows say with a grain of salt but I can't seem to find any actual studies or mention of this.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 ro...

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
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 ...

d) The strand of DNA, the enzyme forms DNA fragments in small piece again in 5^(')to 3^(') direction initiatiating from RNA primer. The primer is formed with the help of primase enzyme.
2.The two strands of DNA are held together by hydrogen bonds between the nucleotides- A=T, C forms three hydrogen bonds with guanine. 3.The width of each turn is around 34 Angstrom and has around 10 base pairs per turn. 4.The frequency of twist depends ...
