DNA Replication and Repair

DNA Replication and Repair. Concept 13.2: Many proteins work together in DNA replication and repair. The relationship between structure and function is manifest in the double helix Watson and Crick noted that the specific base pairing suggested a possible copying mechanism for genetic material.

DNA Replication

DNA Replication. DNA Length. DNA molecules are surprisingly long. The nucleus of a human cell contains more than 1 meter of DNA. DNA must be folded and coiled in order to fit in such a small space. Structure of Chromosomes. Chromosomes are made up of chromatin .
