DNA: Structure, Function, and Replication
... ● Knew DNA was composed of nitrogen base (A, T, C, G), sugar, and a phosphate group (nucleotide) ● Analyzed DNA composition of many species of organisms and came up with Chargaff’s rules: - adenine and thymine are present in roughly equal amounts - cytosine and guanine are present in roughly equal a ...

Genetics 2 – Inheritance of Variation
... 3. Describe the inheritance of variation Variation can occur at two main stages At metaphase I (of meiosis I) where the homologous pairs of chromosomes line up along the equator of the cell. The combination of different chromosomes in the different daughter haploid cells can lead to variation. A ...

RNA Structure and Function
... 2. This system allows the DNA to be held in a protected area of the cell, yet still be used. It is analogous to a “reference book” within a library. The information must be copied from the master copy to be removed from the protective location and used in a remote location. 3. The information is co ...

In lactose media lacking glucose, the operon is turned on and transcription occurs at the highest rate. cAMP is synthesized in the absence of glucose, and the CAP-cAMP complex ...
