DNA, RNA and Protein Synthesis

DNA, RNA and Protein Synthesis. TAKS Review Spring 2012. Structure of DNA. DNA is deoxyribonucleic acid DNA is a large molecule that has subunits called nucleotides . The nucleotides come together to make the DNA molecule in the shape of a double helix (looks like a twisted ladder).

REPLICATION

REPLICATION. Chapter 7. The Problem. DNA is maintained in a compressed, supercoiled state. BUT, basis of replication is the formation of strands based on specific bases pairing with their complementary bases. ? Before DNA can be replicated it must be made accessible, i.e., it must be unwound.
