3. DNA Replication 1. The double helix unwinds. 2. Weak hydrogen bonds between nitrogenous bases break and two DNA strands unzip (separate). 3. Each original DNA strand serves as a template on which its complement is built. 4. Free nucleotides build a DNA strand onto each of the original two DNA strands by attaching to their

CHAPTER 5 DNA REPLICATION I: Enzymes and mechanism
www.bx.psu.eduDNA replication. Basic Mechanisms of Replication DNA replication is semiconservative. We begin our investigation by describing the basic model for how nucleotides are joined in a specific order during DNA replication. By the early 1950’s, it was clear that DNA was a linear string of deoxyribonucleotides.

Forensic DNA analysis - Royal Society
royalsociety.orgForensic DNA analysis focuses on examining specific sections of DNA that are known to be particularly variable between individuals in order to create a DNA profile. The part of the DNA that is examined is called a locus (plural loci), which is a unique site along the DNA of a chromosome characterised by a specific sequence of bases. Currently, an
