DNA is made up of two strands and each strand of the original DNA molecule serves as a template for the production of the complementary strand, a process referred to as semiconservative replication.Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.NA polymerase adds a new strand of DNA by extending the 3' end of an existing nucleotide chain, adding new nucleotides matched to the template strand one at a time via the creation of phosphodiester bonds.
He made his first recordings with that band in 1923. In 1929 Armstrong appeared on Broadway in Hot Chocolates, in which he introduced Fats Waller 's Ain't Misbehavin', his first popular song hit.
When Louis Armstrong recorded Hello, Dolly in 1963, he became the oldest act to top the US charts when his recording reached number one in 1964 knocking the Beatles clear off the charts!

Wilder revised and retitled The Matchmaker in 1955.
