DNA Structures - Coggle Diagram

- - - - comprise of non-coding sequence repeats
  - - - propeller-like arrangement.
- - - - Folded single stranded DNA
        
        several bases remain unpaired before strand loops back upon itself.
    - - Use for transcription termination
      - Signal to RNA polymerase to stop transcribing in prokaryotes
    - - Occurs when DNA strand contains complimentary bases in correct sequence to those that appear earlier in strand.
  - - - Cruciform
        
        Cross-shaped structure
    - - modify access of proteins to certain part of the DNA sequences
      - Certain type of proteins can directly recognize & bind to cruciform
    - - Formation is by negative supercoil and requires centre of IR symmetry
- - - - cross-shaped
      - 2 homologous duplexes linked by reciprocal exchange of pair of DNA strands
    - - allows for exchange of genetic information to occur due to similar sequences
    - - Cutting of DNA
      - Religation of DNA
      - Resolution
