Structure of DNA and Nucleotides DNA is arranged into adouble helixstructurewhere spirals of DNA are intertwined with one another continuously bending in on itself but never getting closer or further away (see diagram to the below right).
Figure 3. DNA has (a) a double helix structure and (b) phosphodiester bonds. The (c) major and minor grooves are binding sites for DNA binding proteins during processes such as transcription (the copying of RNA from DNA) and replication....
Fig 1 – Diagram showing the difference between the structure of DNA and RNA Stages of DNA replication DNA replication can be thought of in three stages:initiation, elongationandtermination Initiation DNA synthesis is initiated at particular points within the DNA strand known as ‘origins’, which ...
