DNA Replication is Semiconservative ... DNA replication begins with the "unzipping" of the parent molecule as the hydrogen bonds between the base pairs are broken. ... The single molecule of DNA that is the E. coli genome contains 4.7 x 106 nucleotide pairs. DNA replication begins at a single, fixed location in this molecule,

DNA replication , the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "semiconservative" in that each strand of the ori...

A simplified representation of a DNA molecule separating to form two new molecules. To reproduce, a cell must copy and transmit its genetic information (DNA) to all of its progeny. To do so, DNA replicates, following the process of semiconservative replication.

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 nucleotides are very particular about what they connect to.

Now that we have seen how genetic information encoded in the nucleotide sequences of DNA is translated into the structures of proteins that perform most cell functions, we can appreciate the necessity of the precise copying of DNA sequences during DNA replication.

Most living organisms have the same sort of genetic material, DNA, in their cells. DNA contains two strands wrapped around each other in a helix, and these strands are held in place by four chemicals called bases: adenine (A), guanine (G), cytosine (C) and thymine (T). Read More »...
