Telomere DNA structure and the binding proteins in model organisms. Molecular Genetics. - In eukaryotes, chromosomes bear the genetic information that is passed from parents to offspring.a. A chromosome prior to replication contains a single DNA molecule b. A chromosome that has been replicated and consists of two chromatids : Molecular Genetics. I. Structure/Function of DNA and RNA .Semiconservative replication results in two double-stranded molecules of DNA each consisting of one old strand of DNA (template) and one new strand (complementary strand). This structure explains both important functional aspects: replication and the transmission of genetic information. The elucidation of the structure of DNA is considered as the beginning of the development of modern genetics. With it, gene structure and function can be understood at the molecular level.

This analysis and discussion activity can be used to introduce your students to key concepts about the structure, function and replication of DNA or to review these topics. This activity includes hands-on modeling of DNA replication. DNA Structure and DNA Replication Errors. The DNA molecule looks like a twisted ladder spiraling around its long axis. The outside supports of this ladder are made up of a five carbon sugar and a phosphate group.
