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 ...

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 ...

A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines.

This structure, announced in their famous paper in the April 1953 issue of Nature, explained how the DNA molecule could replicate itself during cell division, enabling organisms to reproduce ...

When a cell divides, it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. The nucleotides (A ...

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 ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

Researchers at The University of Hong Kong (HKU) have made an exciting discovery about how human cells protect DNA during ...

People genetically susceptible to Huntington's disease often see their movement, mood, and cognition decline slowly over time.

Brain cells receive sensory inputs from the outside world and send signals throughout the body telling organs and muscles ...
