During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer.

The first section of the book, Cellular DNA Replication, begins with an excellent overview of genome duplication by Thomas J. Kelly and Bruce Stillman, followed by chapters on specific steps in ...

Mitochondrial deoxyribonucleic acid (mtDNA) is essential for cellular energy production and overall cell function.

Conjugation is a form of horizontal gene transfer that allows the exchange of genetic material between two organisms or cells ...

During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

The CBSE Class 12 Biology exam, set for March 25, 2025, demands more than memorization—it requires conceptual clarity, ...

DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells ...

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

This process is essential for the proper functioning and survival of all living organisms. DNA replication is the process by which the DNA molecule makes an exact copy of itself during cell division.
