A clearer understanding of the origin recognition complex -- a protein complex that directs DNA replication -- through its crystal structure offers new insight into fundamental mechanisms of DNA ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Genetics is the study of heritable changes in gene activity or function due to the direct alteration of the DNA sequence. Such alterations include point mutations, deletions, insertions, and ...

Failures in DNA replication can lead to cancer, birth defects or other harm Video shows single pieces of double-helix DNA being copied Single-molecule view gives new insights into this process ...

In eukaryotic cells, chromosomes are made up of DNA. DNA can also be found in the chloroplasts and mitochondria, and inside the cytoplasm in the form of plasma. DNA molecules consist of nucleotides ...

DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two ...

Before a cell divides and DNA is passed from one cell to another, a complex process occurs. The DNA strands unwind and separate. Each strand makes a complementary strand by adding the appropriate ...

Within the nucleus of every cell are long strings of DNA, the code that holds all the information needed to make and control every cell within a living organism. DNA, which stands for deoxyribonucleic ...

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein. Actually, ...

A new study has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some circumstances, including cancer. A new study from scientists at the ...
