Document Summary
Dna structure and the central molecular biology dogma. Gene number, protein number and the central dogma. At the end of this module, you should have reviewed some concepts you are already familiar with and should be able to: Describe the structure of nucleotides and of dna. Draw hydrogen bonds between bases in a dna double helix, in a dna- Rna hybrid or in a rna-rna double stranded structure. Name and describe the main steps in the transmission of genetic information according to the central dogma. Name and describe briefly a few examples of exceptions/deviations to the central dogma. Panel 2-6 molecular biology of the cell 4th edition. Dna is made of two chains or strands of nucleotides that warp around each other to form a double helix. The two strands adopt an anti-parallel orientation, thus having opposite 5" to 3" polarities. The two chains are linked to each other by hydrogen bonds between the bases.
